Instead of serving merely as auxiliary tools that “replace human eyes for static inspection", vision technology has evolved into the perception and decision-making core that underpins dynamic interaction of embodied devices. Three distinct transformation paths have taken shape across the global industry: established international leaders including Cognex, Keyence and Basler adhere to the traditional vision tool route; cross-industry players such as Tesla and Huawei introduce vehicle-grade and full-stack technology ecosystems; Chinese frontrunners including Hikrobot, Mech-Mind, Unitree and Galaxy Robotics focus on industrial deployment of integrated “Eyes-Brain-Hands" systems. Drawing on public industrial data and real-world deployment cases of leading enterprises from 2021 to 2026, this paper sorts out the evolutionary logic of machine vision technology from “capturing static 2D planes" to “empowering dynamic 3D scenarios". It comprehensively analyzes the technical paradigms and commercial practices of established international incumbents, cross-industry giants and emerging Chinese specialized enterprises, thoroughly dissects the reshaping rules imposed by embodied technology deployment on the vision sector, and ultimately derives the fundamental logic governing technological divergence, commercial restructuring and scenario selection within the industry. Keywords: Machine Vision; Embodied Intelligence; Technical Route; Business Model; Industrial Manufacturing; Industrial Transformation Introduction: When the “Industrial Eyes" Gain a “Brain and Hands" Within the classic paradigm of industrial automation, the core value of machine vision has long been confined to a single dimension: high-precision industrial inspection. Its technical logic is fully bound to standardized scenarios at static workstations. Typically, cameras are fixed at designated positions to capture planar images of stationary or uniformly moving workpieces. Predefined rules regarding geometry, grayscale and texture then enable all judgments, ranging from micron-level defect detection to millimeter-scale dimensional measurement. Under this framework, vision systems function as independent “third-party inspection units" separated from production equipment. They are completely decoupled from the motion control systems of production lines and can only operate during intervals when materials remain static. Their technical value is limited to improving precision and speed at individual processes or replacing manual labor. Even core technical solutions iterated by leading industry players have failed to break free from this logic. Vision systems from Keyence, image processors from Cognex, and industrial cameras manufactured by Basler are essentially optimized toward capturing clearer images and executing more accurate rule-based comparisons. When the scope of industrial manufacturing scenarios remained relatively stable, the maturity and reliability of this technical system sustained the long-standing landscape of the global mid-to-high-end vision market. At one stage, Cognex and Keyence together held nearly 50% of the global mid-to-high-end market share. Over the past decade, however, as the core demands of industrial manufacturing shift from “automation" toward “autonomy", clear ceilings for traditional vision technology have emerged in practical applications. This demand shift stems from fundamental changes in industrial production. Large-scale rigid production lines are being replaced by flexible production lines supporting multiple product varieties and small batch sizes. High-end production lines in the 3C electronics, automotive and lithium battery industries frequently need to switch production workflows for dozens of material types on a single line. Even traditional food and pharmaceutical sectors require inspection compatibility for diverse specifications and packaging formats. Against this backdrop, the emergence of embodied intelligence elevates machine vision from a supporting auxiliary inspection tool to the central perception and decision-making hub for robots. The shift from automated to autonomous industrial production demands vision systems evolve thoroughly from the mode of “passive imaging, static inspection and isolated output" toward a brand-new paradigm of “active perception, dynamic modeling and decision-driven output". This paradigm shift poses far greater technical challenges than accumulated industry experience. To support stable operation of embodied devices in industrial environments, vision technology must not only “see" objects but also “understand" them. It needs to collect not only 2D planar information, but also multi-dimensional data including spatial pose, material deformation and even force feedback generated during operation. Visual data must further be converted into motion control commands to enable real-time coordination with mechanical actuators. From the perspective of technological evolution, this transformation essentially represents the transition of machine vision from rule-based single-dimensional inspection to multimodal perception, deep learning and real-time 3D modeling. This is not merely iteration of technical routes, but a reconstruction of the industry’s value logic. The industry once centered on “how to capture clearer images"; today the focus lies on “how to enable robots to complete tasks autonomously via visual perception". Such restructuring has thoroughly rewritten competitive dynamics across the sector. Faced with the industrial wave of embodied intelligence, global leading enterprises are redefining their technical roadmaps and industrial positioning. Divergent transformation paths have emerged owing to disparities in accumulated resources. Established international vision giants represented by Cognex, Keyence and Basler stick to long-term technical moats in standardized vision tools, positioning themselves as core vision component suppliers within embodied intelligence ecosystems. Platform companies expanding from upstream and downstream sectors such as Tesla and Huawei leverage strengths in large AI models, core computing power and ecosystem integration to enter high-end industrial markets with closed-loop “perception-decision-execution" solutions. Chinese enterprises including Hikrobot, Mech-Mind, Unitree and Galaxy Robotics rely on in-depth understanding of local industrial scenarios, end-to-end full-stack integration capabilities and efficient supply chain responsiveness to deliver scenario-based deployments and realize end-to-end substitution for overseas incumbents. Based on public industry data and practical cases of leading companies from 2021 to 2026, this paper analyzes the technical paradigms, commercial logic and deployment progress of the three types of enterprises from multiple dimensions, sorts out underlying patterns of industrial transformation, and reveals the reshaping logic of the machine vision industry in the embodied intelligence era. 1.0 Established International Incumbents: Upholding the Tool Ecosystem Amid Marginalization Over the half-century development of machine vision, Cognex (US), Keyence (Japan) and Basler (Germany) are widely recognized as the founders and long-term leaders of the industry. Cognex and Keyence once jointly captured nearly 50% of the global mid-to-high-end vision market, while Basler maintains an irreplaceable reputation in high-end industrial camera supply. Amid the rise of embodied intelligence, the technical and commercial strategies of these enterprises serve as a benchmark for industry observation. Their core strategic choice is to pursue incremental adaptation built upon existing technical frameworks, rather than fully shifting toward full-stack embodied intelligence solutions. This strategic choice stems fundamentally from these companies’ judgment on their core competitive moats. They still regard “high-precision imaging" as the core value of vision technology and believe embodied intelligence essentially represents “downstream integration built upon traditional vision tools", rather than a new technical paradigm replacing conventional vision solutions. As a direct consequence, their transformation paths are strictly confined within the boundary of “supplying core vision components for embodied intelligent products". They refrain from developing complete robot systems or end-to-end integrated “Eyes-Brain-Hands" solutions, and merely supply their mass-produced high-end industrial cameras, lenses and sensors to robot integrators and embodied equipment manufacturers. German industrial camera giant Basler serves as a typical example of this strategy. 1.1 Basler: The Marginalization Choice of a Core Component Supplier Within the established framework of the traditional vision industry, Basler is synonymous with premium industrial cameras, consistently holding a leading share in the global mid-to-high-end industrial camera market. Nevertheless, amid the emerging embodied intelligence track, the German enterprise opted against developing full-stack solutions and even avoided extensive proactive technical adaptation. Instead, it continued its supply logic for conventional industrial scenarios: selling industrial cameras to manufacturers of embodied equipment. This “adapting to changes by maintaining stability" strategy only underwent minor adjustments in 2025. In the second half of that year, Basler entered a strategic cooperation with Obi Zhongguang, a domestic leader in 3D vision. The core of the partnership lies in combining Basler’s industrial cameras with Obi Zhongguang’s 3D vision technology to jointly launch integrated 3D vision solutions tailored for industrial environments. Notably, Basler remains positioned purely as a core hardware supplier within this collaboration: it provides imaging-side industrial cameras, while Obi Zhongguang takes charge of subsequent algorithm adaptation, system integration and project delivery coordination with robot vendors. This partnership clearly defines Basler’s role in the embodied industrial chain: leveraging its long-standing technical accumulation in high-end imaging to remain a standardized core component supplier. The merit of this strategy lies in low risks for technology investment. Without allocating extra resources to build new capabilities such as motion control and process know-how, the company can secure its position in the industrial chain simply by sustaining the competitiveness of existing products. In the long run, however, this path exposes such enterprises to marginalization risks. Within the embodied intelligence industrial chain, high-value segments have shifted away from hardware manufacturing toward algorithm adaptation, system integration and on-site process implementation. The technical value of traditional hardware vendors can only be unlocked through downstream integrated solutions. This means they lose pricing power and cede the incremental dividends of industrial growth to integrators and robot OEMs. 1.2 Keyence: Passive Adaptation Logic for Hand-Eye Integration Compared with Basler’s minimal adjustment strategy, Keyence has adopted a relatively more progressive technical roadmap among established incumbents. Even so, its development remains incremental iteration within its original technical framework, far from genuine transformation toward embodied intelligence. As a global leader in the vision sector, Keyence’s competitive moat has long rested on the tight synergy between hardware and algorithms. Its traditional vision systems feature fully self-developed cameras, lenses and algorithms, delivering benchmark imaging accuracy, stability and anti-interference performance under harsh industrial conditions. Keyence’s solutions consistently capture a prominent share in the global high-end industrial vision market. Responding to the embodied intelligence trend, Keyence’s major technical move came in 2025 through the co-launch of the HKE-01 vision application solution with Huayan Robotics. The technical logic combines Keyence’s laser vision technology with Huayan Robotics’ high-precision manipulators. Keyence provides cutting-edge laser scanning vision technology to acquire geometric information of targets, while Huayan Robotics supplies high-precision robotic actuators. In terms of specifications, the solution meets industrial-grade standards: it completes 3D data acquisition of targets within 0.2 seconds, with scanning repeatability up to 0.3 μm. Technically speaking, however, it amounts to a simple combination of “vision inspection tool plus robotic actuator", failing to break the underlying logic of independent inspection adopted by traditional vision systems. More importantly, Keyence stays out of core embodied technology links under this cooperation. Algorithms coordinating vision systems and robot motion control are developed by Huayan Robotics, which also takes charge of scenario process adaptation. Consequently, Keyence’s vision system still functions as an independent auxiliary inspection unit. It merely transmits inspection data to robot controllers without forming a complete “perception-decision-execution" closed loop. In complex industrial settings, the system cannot adjust robot trajectories in real time according to visual feedback. It still follows the conventional workflow: robots move to fixed positions first, and then vision systems conduct inspections. 1.3 Cognex: An Industry Giant Absent from Core Closed-Loop Systems Compared with Basler and Keyence, another industry leader Cognex has made even slower progress in embodied intelligence layout. It was not until the South China Industry Fair in June 2026 that the giant appeared at exhibition zones related to embodied intelligence solely as a vision solution provider. Prior to that, nearly all of Cognex’s technical resources were devoted to conventional 2D/3D vision inspection solutions, with no involvement in any core embodied technologies. According to public information, Cognex failed to roll out new solutions specially optimized for embodied scenarios even at the 2026 South China Industry Fair. The vision products on display remained mature standardized solutions originally designed for premium industrial inspection. No newly released technologies for robot coordination or technical binding partnerships with robot manufacturers were announced. This confirms that Cognex occupies exactly the same market position as Basler within the embodied intelligence track: a core supplier of standardized vision products. Behind this choice lies a dilemma confronting these traditional giants. They possess profound technical barriers in conventional vision technology, alongside well-established global distribution networks and customer resources. A full-stack transformation toward embodied intelligence would require massive investment to develop motion control and process expertise where they have no prior accumulation. More critically, such a shift would directly encroach on the interests of downstream integrators and robot manufacturers, potentially triggering resistance from key clients. Conversely, stagnation risks gradually pushing them from core system suppliers to peripheral supporting vendors amid ongoing industrial technological iteration. In the early phase of industrial development, this “no-change" strategy enables these enterprises to maintain steady revenue growth. Nevertheless, significant hidden risks emerge over the long term. As embodied technologies mature, downstream integrators will shift their priorities for vision solutions from imaging accuracy to coordination efficiency with motion control — a well-documented technical weakness of traditional giants. In practice, market shares of such enterprises have already shown signs of decline amid industry technological evolution. 1.4 The Fatal Limitation of “Tool-Oriented Mindset" Among Established Incumbents From the perspective of technological evolution, a shared trait of these international legacy vision enterprises is their failure to grasp the essential reshaping brought by embodied intelligence to the vision industry. They continue to treat high-precision imaging as vision technology’s core value, overlooking the shift within embodied intelligence: vision’s core function has evolved from “capturing clear images" to “outputting executable spatial coordinate commands". This divergence in technical logic foreshadows their marginalization. In the embodied intelligence industrial chain, vision constitutes merely one segment of the “perception-decision-execution" closed loop. To deliver industrially viable solutions, vision systems must achieve deep integration with robot motion control and operational process logic — a capability gap plaguing traditional players. The constraints of this tool-oriented mindset are especially evident in industrial scenarios. Traditional vision solutions are designed on the premise that work environments can undergo standardized reconstruction. For instance, dedicated enclosed lighting, background panels and pre-positioning mechanisms are commonly installed on production lines to eliminate interference and guarantee imaging quality. By contrast, the core value of embodied intelligence lies in enabling flexible operation within complex environments that cannot be pre-modified. This demands vision systems to accomplish identification, positioning and data transmission reliably amid backlight, dust and material deformation — requirements incompatible with the imaging logic of traditional vision equipment. From the viewpoint of industrial competition, this strategic stance also means these enterprises voluntarily surrender high-growth market opportunities. Within the traditional industrial vision chain, these firms act as primary solution providers with dominant pricing power. In the embodied intelligence ecosystem, however, their technical value can only be realized through downstream integration. As a result, incremental industry profits increasingly flow toward integrators and robot OEMs equipped with full-stack capabilities and direct access to end-user scenarios. 2.0 Cross-Industry Giants: Technological Invasion by Platform-Based Ecosystem Players Unlike the passive adaptation adopted by traditional vision vendors, platform enterprises expanding from autonomous driving and smart hardware sectors represent typical agents of technological invasion. Their core strengths stem from long-term R&D investment in large AI models, computing ecosystems and multimodal technologies. Rather than iterating conventional vision schemes, they enter embodied intelligence by migrating their existing technical capabilities to robotics applications. Tesla and Huawei stand out as typical representatives. The former directly transfers its autonomous driving vision framework to humanoid robots; the latter leverages full-stack strengths built by its machine vision division to penetrate the sector via vertical industry solutions. Differing from traditional vision firms positioning themselves as component suppliers, these platform players aim to build complete “perception-decision-execution" technical closed loops and emerge as core technology leaders within embodied intelligence. This technical roadmap aligns fully with their long-term ecosystem development strategies. 2.1 Tesla: From FSD to Optimus — Hard Technical Reuse Under a Vision-First Philosophy Among the global embodied intelligence track, Tesla’s Optimus humanoid robot ranks among the most widely discussed products. Its core technical advantage lies in migrating vision technology accumulated for autonomous driving directly to robotics scenarios. This cross-domain technology reuse forms Tesla’s unique competitive moat. Tesla’s Full Self-Driving (FSD) autonomous driving system has been refined with billions of kilometers of real-world driving data worldwide. Fundamentally, the technical logic of Optimus transfers autonomous driving technology originally built for “four-wheeled mobile robots" to bipedal embodied robots. Technically, the two systems share homologous architectures. The perception layer centers on vision; the decision layer adopts Transformer-based neural networks; the computing layer relies on Tesla’s in-house AI chips. Within autonomous driving, FSD leverages visual perception to understand surrounding environments and convert visual data into vehicle motion control commands. Tesla transplanted this entire technical stack to robots. On the hardware side, Optimus Gen3 is equipped with eight Autopilot cameras derived from autonomous driving hardware, forming a 360° full-field perception system. On the computing side, Tesla’s proprietary AI chips sustain the heavy computational demands of real-time image processing. On the algorithm side, the original monocular detection branch has been selectively modified, with newly added binocular depth estimation hardware units to satisfy 3D perception requirements for robotic applications. The primary merit of this architecture lies in extreme technical maturity. The recognition accuracy of the FSD vision system has been fully validated by massive volumes of real road data globally. This means Optimus’s vision system does not need to build scenario capabilities from scratch; it only requires adapting autonomous driving perception logic to industrial environments. According to Tesla’s public test data, the Optimus Gen3 vision system achieves a recognition accuracy of 99.2% for reflective, dark-colored and curved workpieces commonly seen in industrial settings, placing it at an advanced industry level. Nevertheless, this technical roadmap carries inherent adaptation limitations. Its underlying vision-only approach creates natural contradictions against core industrial requirements. In autonomous driving, vision systems mainly identify macro environmental features such as roadways, vehicles and pedestrians, where centimeter-level perception precision suffices. In industrial manufacturing, however, vision systems for embodied devices must detect micron-scale workpiece defects and precisely locate assembly holes down to 0.1 millimeters, demanding far higher perception accuracy. More critically, industrial sites feature abundant high-gloss, reflective and transparent materials, for which vision-only solutions deliver inferior imaging performance compared with multimodal fusion architectures. Under harsh industrial conditions involving dust, water mist and vibration, vision-only systems also exhibit weaker stability. This constitutes the core reason Tesla’s Optimus has yet to achieve large-scale deployment in high-end industrial manufacturing. 2.2 Huawei: Cloud-Edge-End Collaborative Layout Led by the Machine Vision Corps Unlike Tesla’s direct technical reuse strategy, Huawei enters the embodied intelligence track starting from vertical industry scenario solutions, underpinned by its Machine Vision Corps formally established in 2022. The strategic positioning of this corps frames machine vision as core perception technology for full-scenario applications including intelligent vehicles, smart factories and smart cities, rather than merely serving the niche industrial manufacturing sector. Its core technical layout builds on a cloud-edge-end collaborative architecture to deeply integrate vision technology with industrial process scenarios. From a technical perspective, Huawei’s vision solutions revolve around cloud-edge-end synergy. The terminal layer comprises a full lineup of industrial cameras, 3D structured-light sensors and other perception hardware for collecting multi-dimensional raw visual data. The edge layer features the VAC series AI inference terminals supporting parallel processing of multiple algorithms, responsible for real-time processing and analysis of visual data to transform raw images into scenario-aware perception information. The cloud layer leverages Huawei Cloud’s massive computing power to deliver one-stop services covering vision algorithm training, optimization and simulation, sustaining continuous algorithm iteration. The key strength of this architecture lies in flexible allocation of computing resources according to real demands of different industries: latency-sensitive industrial tasks run computations at the edge, while large-scale data training and simulation workloads are supported via cloud resources. Contrary to Tesla’s vision-only scheme, Huawei adopted a multimodal fusion roadmap from the outset, a choice rooted in genuine industrial needs. Single vision systems cannot cope with extreme operating conditions on production lines. For instance, vision systems need to capture 3D coordinates of welding spots in automotive welding workshops. In dusty and vibrating environments, pure visual information suffers severe interference, requiring supplementary data from LiDAR and contact sensors to guarantee accuracy. Accordingly, Huawei’s embodied vision technology centers on multimodal fusion of “vision + LiDAR + Inertial Measurement Unit (IMU)". Information complementarity across different perception sensors enables robust operation amid complex lighting, dust and vibration in industrial sites. A core technical challenge for this approach involves spatio-temporal alignment and fusion calibration of multi-sensor data. Unified environmental perception outputs free of conflicts can only be generated after precise registration of multimodal data across time and spatial dimensions. A representative deployment case of this technical solution is the industrial embodied intelligence workstation jointly developed by Huawei and Topstar. Within this project, Huawei provides the multimodal visual perception scheme and cloud-edge-end collaborative computing infrastructure, while Topstar delivers robotic arms, motion control systems and scenario process adaptation logic. The combined technical stack forms a complete “perception-decision-execution" closed loop within the workstation. After capturing visual data of workpieces, the vision system transmits information in real time to edge-side algorithms, which rapidly compute the 3D spatial coordinates of targets. These coordinate values are then converted into motion control commands guiding robotic arms to complete precise sorting and palletizing. Measured performance places the solution among industry leaders: visual recognition accuracy reaches 99.9%, and the robotic arm boasts repeat positioning accuracy of 0.02 mm. It supports over 1,800 grasping operations per hour on high-takt production lines, fully meeting mass-production industrial standards. 2.3 Ecological Advantages and Inherent Shortcomings of Cross-Industry Giants From an evolutionary standpoint, the technical roadmaps of Tesla and Huawei represent another typical transformation pathway in the industry. Instead of starting from traditional industrial vision technology, they penetrate embodied intelligence via large AI models, computing platforms and ecosystem integration. The core advantage of this approach lies in comprehensive technical ecosystem support. Their accumulated expertise in computing power, foundation models, multimodal coordination and simulation environments cannot be replicated by traditional vision vendors in the short term. More importantly, these enterprises inherently adopt a full-stack technical perspective, unburdened by the conventional mindset that “vision technology acts merely as a third-party inspection tool". This divergence in mindset manifests clearly in their understanding of vision’s value. Traditional vision companies define the value of vision technology as “capturing clear, precise images". For cross-industry platform players, vision exists to supply “executable perception data" for the entire robotic operation closed loop. Consequently, their technical solutions are architected natively to coordinate with motion control and production workflows, free from the disjointed technical drawbacks plaguing conventional vision systems. Even so, their technical strategies carry inherent adaptation constraints. Their platforms are essentially general-purpose technical foundations applicable across all industries. However, the most critical capability required for industrial-grade embodied intelligence deployment is deep comprehension of process workflows within vertical sectors. Such expertise demands long-term scenario accumulation and iterative testing on live production lines. Cross-industry giants predominantly allocate resources toward general underlying technology platforms, leaving obvious capability gaps in process adaptation for segmented vertical markets. This shortcoming manifests practically: their solutions have not yet achieved large-scale mass deployment within high-end industrial scenarios. Tesla’s Optimus robots remain confined to limited test stations inside its own factories in public deployments. The industrial embodied intelligence workstation co-developed by Huawei and Topstar has not secured volume production orders. During technical evaluation by industrial clients, solutions from these companies are typically shortlisted only for technology verification, rather than being prioritized for mass-production projects. 3.0 Leading Chinese Enterprises: Full-Stack Breakthrough of Scenario-Focused Deployers Distinct from technical roadmaps pursued by international giants, domestic leading enterprises precisely position themselves around end-to-end industrial scenario deployment capabilities. Their shared consensus holds that the technical value of embodied intelligence can only be validated through mass production on real factory floors. Their core competitiveness stems from deeply integrating mature vision technology with genuine process requirements of domestic industrial environments, rather than competing purely on imaging metrics or algorithm theoretical performance. Enterprises following this logic fall into two tiers. The first tier consists of comprehensive frontrunners including Hikrobot and Mech-Mind Robotics, centered on integrated “Eye-Brain-Hands" full-stack capabilities covering mainstream industrial scenarios across all sectors. The second tier comprises specialized firms such as Unitree Robotics and Galaxy Robotics. Their core competitive advantage lies in deep coordination between robot body motion control and visual perception, and they have achieved substitution against overseas leading solutions within segmented vertical applications. 3.0 Leading Chinese Enterprises: Full-Stack Breakthrough of Scenario-Focused Deployers Distinct from technical roadmaps pursued by international giants, domestic leading enterprises precisely position themselves around end-to-end industrial scenario deployment capabilities.

Their core competitive advantage lies in deep coordination between robot body motion control and visual perception, and they have achieved substitution against overseas leading solutions within segmented vertical applications. 3.1 Hikrobot: Full-Stack Layout Under the “Embodied Intelligent Manufacturing" Philosophy As a domestic pioneer in the machine vision sector, Hikrobot’s transformation path clearly reflects how leading Chinese vision enterprises understand the embodied intelligence era. In 2026, Hikrobot formally proposed the industry philosophy of Embodied Intelligent Manufacturing. At its core, this paradigm extends vision technology from an independent inspection module to the full workflow of robotic operations, thereby reconstructing the company’s value proposition for technology. In terms of technical layout, Hikrobot’s core strategy leverages full-stack technical capabilities to connect the entire chain from visual perception to motion control. This framework is underpinned by its comprehensive portfolio of vision products. At its 2026 new product launch, Hikrobot unveiled more than 35 new machine vision products, spanning high-precision area-scan cameras, industrial-grade 3D structured-light sensors and AI inference terminals, fully covering multi-dimensional imaging demands in industrial settings. More importantly, the underlying technology of these vision products is deeply adapted to Guanlan, Hikrobot’s self-developed industrial vision foundation model. This means image data captured by its vision solutions can be processed directly on its proprietary algorithm platform without extra adaptation work. The true core of this technical architecture is Vision-Motion Integration, which delivers deep fusion of visual perception and motion control and thoroughly eliminates the technical disconnect between conventional vision systems and motion controllers. To realize this goal, Hikrobot has built multi-dimensional capabilities beyond traditional vision technology, including motion control and industrial process know-how. On the robotic side, the company independently develops core algorithms for robot motion control. For vertical sectors including automotive, lithium batteries, 3C electronics and logistics, it has built supporting algorithm libraries for vision-motion coordination. In practical scenarios, the solution operates within a complete “perception-decision-execution" closed loop. After capturing 3D image data, the vision system transmits information in real time to edge inference terminals, which rapidly calculate precise 3D spatial coordinates of workpieces. Coordination algorithms then convert coordinate data into executable commands for robot motion controllers, guiding manipulators to complete grasping, assembly and inspection tasks. Within this workflow, the vision system is no longer a third-party inspection unit but the active initiator of the entire operation. Field deployment results rank among industry benchmarks. Within automotive manufacturing, Hikrobot’s Vision-Motion Integration solution covers full-process stages including component inspection, welding positioning and final assembly measurement. Large-scale continuous deployment has been realized on multiple mass-production lines at high-end new energy manufacturing bases of NIO and Changan Automobile. In lithium battery production, the solution has multiplied efficiency compared with manual inspection on pole piece inspection lines at Lead Intelligent Equipment. For logistics, sorting centers of major operators including YTO Express and Wonderlon achieve industrial-grade performance of over 1,800 sorting cycles per hour. Most notably, the solution has completed self-verification. All robots responsible for handling, assembly and inspection at Hikrobot’s Tonglu manufacturing base adopt its proprietary Vision-Motion Integration technology — realizing the scene where robots “manufacture other robots" on mass-production lines. According to Hikrobot’s public data, coordinated positioning accuracy between vision systems and manipulators reaches 0.02 mm across multiple unmanned production lines at the Tonglu base, lifting production efficiency by 243% compared with conventional production lines. 3.2 Mech-Mind Robotics: In-Depth Scenario Cultivation via Integrated “Eye-Brain-Hands" Full-Stack Technology If Hikrobot’s strength lies in comprehensive product coverage, Mech-Mind Robotics’ core competitiveness resides in precise integration of the full “Eye-Brain-Hands" technological chain. This integration capability underpins its ability to replace overseas leading solutions in industrial applications. Public materials show Mech-Mind’s technical roadmap shares strong similarities with Hikrobot: it likewise extends vision technology from isolated inspection procedures to end-to-end robotic workflows, supported by full-stack capabilities for scenario delivery. Nevertheless, unlike Hikrobot’s cross-industry coverage strategy, Mech-Mind pursues clear vertical focus, with core target scenarios concentrated in high-end automotive manufacturing. Its technical solutions are purpose-built to match multi-faceted process requirements within automotive production. This strategy originates from a precise understanding of the core criteria for industrial-grade deployment: in high-end industrial sectors, clients evaluate embodied solutions not merely on theoretical technical indicators, but on how well the technology adapts to segmented manufacturing processes. Only solutions validated through extensive multi-process field testing can win industry recognition. Technically, Mech-Mind’s integrated “Eye-Brain-Hands" solution consists of three core modules. The Eyes refer to self-developed high-precision 3D vision sensors, the fruit of years of R&D accumulation. These sensors accurately identify dark, reflective and curved components commonly seen in automotive manufacturing. They can extract clear edge and hole features even on workpieces contaminated by lubricant stains, meeting high-precision imaging requirements under harsh working conditions. The Brain represents an edge inference system built upon its proprietary Mech-GPT vision foundation model, which converts visual data into executable spatial coordinate commands for robots in real time. The Hands are flexible collaborative manipulators co-developed with leading industry partners, capable of tasks ranging from precision assembly to heavy-load handling. Similar to Hikrobot, Mech-Mind’s architecture delivers tight coordination within the “perception-decision-execution" closed loop. What sets it apart is its industry-leading process adaptation for automotive manufacturing. A typical challenging application is hole inspection on integrated die-cast vehicle bodies. The technical hurdles stem from large curved surfaces on castings and irregular light reflection angles. Traditional vision systems require multiple cameras shooting each hole from separate viewpoints, with the full inspection cycle extending up to four hours, accompanied by frequent missed and false detections. By tightly combining 3D vision sensors with flexible manipulators, Mech-Mind’s integrated “Eye-Brain-Hands" system only requires one sensor to capture comprehensive footage of all holes following pre-defined motion paths. Vision algorithms compute coordinates for every hole within 10 minutes, compressing the total inspection cycle to 1/24 of the original duration. Inspection accuracy reaches an industrial-grade 0.02 mm, fully satisfying mass-production standards. The solution’s deployment capability has been fully verified industry-wide. By 2026, Mech-Mind’s integrated “Eye-Brain-Hands" platform covers full automotive manufacturing workflows: component detection and positioning, vision guidance for stamping and welding, and high-precision assembly in final assembly workshops. Its client portfolio includes domestic leading automakers as well as global giants such as Toyota, BMW and Volkswagen. According to Mech-Mind’s disclosures, cumulative shipments of its automotive solutions exceed 10,000 units, serving more than one hundred top-tier clients across nearly 50 countries and regions. The technology has replaced German and Japanese leading vision systems on certain high-end process stations, representing leading deployment performance among domestic vision enterprises. 3.3 Unitree Robotics & Galaxy General Robotics: Strategic Positioning via Robot-Side Vision Coordination Distinct from vision-originated firms such as Hikrobot and Mech-Mind, Unitree Robotics and Galaxy General Robotics build their core technology foundation upon robot body motion control. Fundamentally, their technical roadmap centers on deep coordination between robot hardware and visual perception, rather than simple integration of off-the-shelf vision modules. Their key competitive strength lies in end-to-end mastery of joint vision-motion control logic. They treat vision as the primary perception input for robotic bodies, not merely an auxiliary inspection module, establishing them as core participants in industrial-grade embodied deployment. Within China’s embodied intelligence track, Unitree Robotics stands out for profound expertise in robot motion control, fully validated by its mature quadruped robot product line. Unitree’s strategy treats vision as core perception input for motion control rather than supplementary inspection capability. Its roadmap relies on deep synergy between high-dynamic motion control of robotic bodies and precise data from visual perception. Technically, Unitree’s vision system combines its self-developed Tianyan Stereo Vision Perception System with mainstream industrial 3D vision sensors. While robots are in motion, the system continuously captures 3D point cloud data of the environment. Processed by proprietary coordination algorithms, spatial coordinates are transmitted in real time to the robot motion controller. The architecture is underpinned by Unitree’s self-developed vision-motion synchronization algorithm, which aligns visual acquisition data and motion control signals within millisecond-level timelines and eliminates imaging distortion caused by high-speed robot movement. Even when the robot travels at high velocity, the vision system can accurately locate target objects and guarantee end-effector precision. The practical performance of this technology has been proven in the field. At Meishan Port of Ningbo Zhoushan Port, Unitree’s Go2 quadruped robot has replaced manual labor to realize fully automated verification of container numbers and seal information. This marks the first industrial deployment of embodied intelligence for customs heavy container inspection within China’s port sector. The solution endured harsh real-world operating conditions: outdoor port lighting fluctuates drastically; large reflective surfaces appear on the ground after rainfall; container shells feature reflective weld seams and oil stains. Furthermore, robots must complete data capture while moving at speed to avoid disrupting regular yard operations. Faced with these extreme conditions, the Go2 vision system still rapidly pinpoints container IDs and seal positions during movement. Image clarity supports optical character recognition (OCR) of container numbers by backend systems, achieving an overall recognition accuracy of 99.9% that meets industrial port standards. Contrary to Unitree’s motion-control-first approach, Galaxy General Robotics builds its competitive edge on visual semantic understanding. From its founding, the company has prioritized deep coordination between visual perception and motion control. Its technical roadmap essentially leverages visual semantic understanding and multimodal perception fusion to enable robots to comprehensively comprehend industrial scenes, instead of merely identifying discrete target objects. Technically, Galaxy’s solution revolves around multimodal visual perception and autonomous decision control. The perception layer adopts a multimodal suite of binocular structured-light 3D vision, LiDAR and IMU to satisfy multi-dimensional imaging demands in industrial environments. The algorithm layer features self-developed spatial semantic understanding algorithms, converting pixel-level visual data into spatial semantic information interpretable by robots. For instance: “A bolt hole is detected with coordinates X, Y, Z; aperture deviation is +0.02 mm; no obvious burrs or scratches around the perimeter." The control layer directly translates this semantic information into manipulator motion commands to guide precise assembly. The core innovation of the solution lies in dual-drive operation: pre-training via synthetic simulation data + alignment with real-scene data. Massive volumes of industrial scene data are generated in simulation environments for algorithm pre-training, followed by targeted fine-tuning using limited real-site data. This pattern drastically cuts algorithm training costs and accelerates iterative deployment. For common scene disturbances including workpiece placement offsets, surface texture variations and mild lighting interference, the system automatically compensates within milliseconds without compromising operational precision. Galaxy General Robotics serves as an early example of large-scale industrial deployment for domestic embodied intelligence technology. In December 2025, the company signed a procurement order for 1,000 embodied intelligent robots with Bada Precision, a leader in precision manufacturing. This represents the largest single order for industrial embodied robots to date within China’s manufacturing sector. Under the agreement, Bada Precision will deploy these robots across full-process production lines covering raw material warehousing, precision machining and quality inspection. The order carries profound industry significance, fully validating the industrial viability of Galaxy’s technology. Bada Precision manufactures precision components for automotive engines, requiring robotic operation accuracy of ±0.01 mm — a benchmark for high-end manufacturing. Galaxy’s solution meets both positioning and execution accuracy requirements while matching production line takt rates. By 2026, Galaxy’s technology has achieved multi-scenario large-scale verification on production lines operated by leading domestic and international clients including CATL, Bosch, Toyota and Hyundai, with cumulative orders reaching thousands of units, ranking among the top domestic vision enterprises. 3.4 The Breakthrough Logic of Domestic Enterprises: Industrial Process Know-How as the Core Moat From an evolutionary perspective, the technical roadmaps of domestic leading enterprises differ fundamentally from international legacy giants and cross-industry platform players. They share a unified consensus: the commercial value of embodied intelligence can only be realized after technical performance is verified on real production floors. Essentially, this mindset means avoiding head-to-head competition with international incumbents over traditional metrics such as imaging precision. Instead, the core competitive battlefield shifts toward understanding vertical manufacturing processes — a capability gap that overseas legacy vendors and cross-industry platform firms cannot close in the short term. Their core strengths combine full-chain system integration capabilities and localized on-site response capacity. They deeply integrate mature vision technology with genuine process demands of domestic factories, rather than forcing production sites to adapt to standardized off-the-shelf technical solutions. This advantage manifests prominently in practice. Most domestic manufacturing sites undergo flexible upgrading built upon existing automated production lines. Accordingly, embodied solutions must adapt to pre-existing operating conditions: factory layout, lighting environments, material conveying modes, takt requirements, and even on-site dust and humidity levels. These highly customized adaptation demands cannot be addressed by imported standardized vision systems, which usually oblige customers to reconstruct production lines according to vendor specifications. Domestic solutions, by contrast, enable scene adaptation without major modifications to existing equipment. More critically, their technical architectures are engineered from the outset to deliver dual advantages in cost control and mass manufacturability. Within industrial manufacturing, clients evaluate embodied solutions based on two core criteria: mass-production stability and reasonable cost. Domestic offerings have established clear substitution advantages against overseas leading products on both fronts. This development path is fully backed by industry statistics. According to disclosures from industrial research institutions, domestic vision solutions captured more than 70% market share within China’s embodied intelligence industry in 2025; penetration is even higher in certain high-end process segments. This data demonstrates that domestic vision enterprises have built new technical moats through differentiated competition within the embodied intelligence track — an industrial breakthrough rarely achievable during the era of conventional industrial vision. 4.0 Trend Analysis & Industry Insights Multi-dimensional comparison of global leading players’ technical roadmaps, business models and deployment outcomes clearly reveals the reshaping logic sweeping the machine vision sector amid the embodied intelligence revolution. Industry competition has transitioned from rivalry over standalone technical products to multi-dimensional comprehensive competition spanning full-stack technical capability, vertical process expertise and ecosystem integration. Fundamental restructuring is underway across technical architectures, commercial models and market landscape. 4.1 Paradigm Shift: From "Passive Inspection" to "Active Interaction" A clear common pattern emerges when examining the technical strategies adopted by leading global enterprises. Regardless of corporate background and resource endowments, their technical roadmaps must align with the core industrial trend: the evolution of vision technology from passive inspection toward active interaction. This represents the established developmental trajectory for vision technology in the era of embodied intelligence. Fundamentally, this trend signals a radical paradigm shift within machine vision. Comparing conventional vision systems against embodied vision reveals changes spanning every core dimension of technical logic: Shift in Core Functions From “capturing clear 2D planar images and conducting pixel-level comparison" to “perceiving complete 3D spatial information and calculating precise spatial coordinates". Accordingly, the evaluation metric for vision technology evolves from imaging accuracy to perception accuracy. Shift in Technical Architecture From standalone 2D/3D vision technology to a full-stack framework integrating multimodal fusion, large AI models and motion control. Vision technology alone can no longer satisfy the requirements of embodied scenarios. Shift in Core Algorithms From rule-based extraction of geometric, grayscale and texture features to deep learning-driven scene semantic segmentation, spatial coordinate calculation and motion trajectory planning. The purpose of algorithms transitions from image matching to generating executable motion commands. Shift in Technical Evaluation Criteria From “capturing clear images under standardized working conditions" to “calculating executable 3D spatial coordinates accurately within unstructured complex environments". Single imaging accuracy ceases to be the primary benchmark for measuring vision technology value. Shift in Technical Role From an independent “third-party inspection unit" separated from production equipment to the core input of a robot’s perception closed loop. Vision systems are no longer passive recorders, but active initiators of the entire operation workflow. This paradigm shift demands thorough reconstruction of traditional vision frameworks. It is not merely incremental iteration built upon existing systems, but the ground-up construction of a complete technical stack featuring multimodal perception, real-time modeling and decision output. Consequently, technical assets accumulated by traditional vision vendors cannot be directly migrated to the embodied intelligence track. Judging from industry deployment progress, the core technical pathways enabling this paradigm shift are well-defined: Multimodal fusion serves as the fundamental prerequisite: To adapt to harsh industrial conditions, solutions must integrate vision, LiDAR, IMUs and force sensors. Complementary data from diverse perception modalities enables robust performance amid fluctuating lighting, dust, vibration and material deformation. 3D vision forms the core technical foundation: Three-dimensional manipulation for embodied intelligence relies on 3D vision to deliver full spatial pose and depth data; 2D vision can only function as supplementary technology. Edge-cloud-end synergy for large AI models provides computing support: Vision technology must be deeply coupled with industrial process logic. Precise semantic understanding requires interoperability between visual perception data, process operation data and business data — a capability sustained by coordinated computing across terminals, edge nodes and the cloud. Vision-motion coordination algorithms constitute the key to successful deployment: A complete operational closed loop can only be realized if visual data is converted into robot-readable motion control commands in real time. Competence in this module directly determines industrial-grade implementation performance. 4.2 Restructuring of Business Models: From "Product Sales" to "Full-Link Scenario-Based Services" A shift in technical paradigms inevitably triggers fundamental restructuring of industry business models. Commercial practices among global leading enterprises have fully proven the inevitability of this transformation. Essentially, the industry’s value logic is transitioning from the traditional model of selling standardized hardware products to a value-added model delivering end-to-end scenario-based services. This shift arises as customer demands evolve from discrete vision hardware toward holistic operation solutions covering visual perception, motion control and process adaptation. Under such new demand conditions, purchasing decisions no longer revolve around selecting vision hardware with superior specifications. Instead, clients prioritize integrated solutions best suited to their manufacturing workflows. Solution providers are therefore required to possess full-stack integration capabilities spanning perception, decision-making and execution, paired with profound expertise in vertical industrial processes. Judging from practical industry deployment, the reshaped competitive landscape has evolved into a tripartite structure. Enterprises of different categories have selected commercial pathways aligned with their respective resource endowments: Path for established international vision giants: Component Supplier These enterprises opt against developing full-stack solutions and remain core suppliers of standardized vision products within the embodied intelligence industrial chain. Leveraging their technical moats in high-end imaging, they supply industrial cameras, sensors and other critical hardware to system integrators and robot OEMs with in-house integration capabilities, capturing incremental market gains through core hardware provision. Path for cross-industry platform giants: Technology Infrastructure Supplier Their core positioning lies in serving as providers of foundational technology stacks for embodied intelligence. Instead of delivering end-user operational solutions directly to industrial clients, they open up their capabilities in computing power, large models and multimodal technology to robot manufacturers and system integrators, offering standardized underlying technical support. Path for leading Chinese enterprises: End-to-End Solution Provider They target end industrial customers by delivering complete integrated “Eye-Brain-Hands" operational solutions with full-process process adaptation. Their internal technical teams cover the entire value chain: perception hardware such as vision sensors, algorithm software, motion control logic, scenario process tuning and post-delivery operation & maintenance services. By deeply embedding technical solutions into customers’ production workflows, they secure sustained incremental revenue from technical services. A pivotal outcome of this restructuring is a fundamental shift in industry profit distribution. High-value segments have migrated away from hardware manufacturing toward algorithm adaptation, system integration, customized process engineering and long-term maintenance services. Across the industrial chain, profit shares captured by upstream hardware suppliers are gradually declining. Meanwhile, integrators and robot OEMs equipped with full-stack capabilities and direct access to end-user scenarios are capturing the majority of newly generated industry profits — a dynamic diametrically opposed to the traditional era of industrial machine vision. 4.3 Industry Outlook: Differentiated Moats and Long-Term Coexistence Based on the technical roadmaps and commercial deployment performance of leading players, three definitive long-term projections can be drawn for the machine vision industry amid embodied intelligence: Projection 1: Established international vision giants will retain hard-to-replace positions in high-end hardware supply. Their technical barriers in premium imaging cannot be replicated in the short run. Domestic solution providers and robot manufacturers will continue procuring their high-end hardware as core perception components. Nevertheless, the market influence of these incumbents will gradually erode alongside the rise of domestic system integrators. Projection 2: Leading Chinese enterprises will become primary beneficiaries of industry growth. As industrial manufacturing shifts from standardized to flexible production requirements, domestic leaders’ combined strengths of full-stack integration and localized on-site responsiveness will emerge as globally competitive advantages. In the foreseeable future, these firms will gradually capture high-end market segments previously dominated by international solution vendors, and achieve large-scale substitution of imported systems in selected premium industrial scenarios. Projection 3: Cross-industry platform giants will act as “hidden providers of underlying technology stacks". Their technological ecosystems constitute vital infrastructure enabling multimodal fusion and large model deployment for robot OEMs and integrators targeting mid-to-high-end scenarios. Constrained by insufficient process know-how, however, these platforms cannot deliver large-scale turnkey solutions directly to end customers and can only participate indirectly as technology stack suppliers. A defining feature of this landscape is the long-term persistence of divergent technical routes. Leading enterprises with varied backgrounds have cultivated differentiated competitive edges rooted in their unique resources, client bases and R&D legacies. These disparities will not disappear as the industry matures; instead, continuous technological iteration will drive further specialization and refined industrial division of labor. 4.4 Industry Insight: Scenario Process Know-How Is the Insurmountable Core Moat From the perspectives of technological evolution, commercial restructuring and competitive outlook, a broad industry consensus has emerged. In the long term, technological advancement, productization capacity and cost advantages do not determine corporate standing. Only profound mastery of vertical scenario processes forms an insurmountable competitive moat. This principle stems from core procu

A Tantalizing Question Shortly after the launch of GPT-4V in early 2023, we received a call from a long-term client. He served as the technical director of a home appliance manufacturer. Two years prior, we had deployed a surface inspection system based on YOLOv5 for their factory, which had been operating stably ever since. He raised a thought-provoking question over the phone: “I’ve seen that GPT-4V can interpret all kinds of images and recognize nearly everything. Can we adopt it directly for quality inspection? Would that eliminate the need for data labeling entirely?" I held back a straightforward answer back then. Truth be told, we were equally captivated by the idea ourselves. Demos of multimodal large models are undeniably impressive. Feed the model any random image, and it can outline contents, pinpoint defects and classify fault types. No training or labeling is required; it delivers zero-shot performance out of the box. If this capability translated seamlessly to factories, the entire rulebook for industrial visual inspection would be rewritten. We spent nearly two years testing diverse multimodal large model solutions across multiple projects. Our conclusion is clear: tempting as the technology may seem, real-world industrial application comes with harsh limitations. This article documents all the pitfalls we encountered over these two years. II. Establish the Current Landscape: YOLO Has Become the De Facto Standard Before diving into multimodal large models, it is critical to lay out the industry baseline: The dominant solution for today’s industrial visual inspection relies on object detection and segmentation models represented by the YOLO series. This is hardly a new trend. Starting from YOLOv3, through the widely deployed YOLOv8, YOLOv9 and YOLOv10, the YOLO family has been implemented in industrial production lines for years, boasting a fully mature technical stack. Why Has YOLO Become the De Facto Standard? First, ultra-fast inference speed. Equipped on standard edge computing boxes paired with industrial cameras, YOLOv8 completes inference for one frame within 10 to 30 milliseconds, matching the takt time of most production lines. Second, sufficient detection accuracy. With adequate labeled datasets, the YOLO series achieves outstanding precision for common defect categories, easily hitting an mAP of over 90%. Third, mature deployment ecosystem. Ready-made toolchains support multiple deployment frameworks including ONNX, TensorRT and OpenVINO. The full workflow from model training to on-site deployment has been validated by countless industrial projects. Fourth, comprehensive open-source ecosystem. The active open-source community provides accessible fixes for most technical hurdles, with abundant pre-trained weights, data augmentation kits and labeling tools readily available. Therefore, the YOLO series is practically the default choice for industrial visual inspection projects launched in 2024. There is no need to debate whether deep learning should be adopted — that question was settled a decade ago. The new core question now arises: With the emergence of multimodal large models, does YOLO still remain the optimal solution? III. The Allure of Multimodal Large Models: A Promising Mirage 2023 witnessed an explosive wave of multimodal large model releases. Models including GPT-4V, Gemini and Claude 3 deliver powerful general image comprehension capabilities. We have run tests on these models, and honestly, their demo performances are truly impressive: Allure 1: Zero-Shot Capability Traditional workflow: To inspect a specific type of defect, you first need to collect, label and train on images of that defect. No data means no usable model. Multimodal large models: Simply describe your demand in natural language, such as “Check whether there are scratches in this image", and the model will return results instantly. No training or labeling required. What does this mean? The cold-start cost drops close to zero. When launching new products, there is no need to spend two weeks on data collection, labeling and model training. You can put the model into use merely with a few lines of prompts. Allure 2: Advanced Semantic Comprehension Traditional models only output bounding boxes and confidence scores, e.g. “A defect exists within this box with a confidence of 0.87". Multimodal large models generate descriptive natural language: “A scratch of around 2cm appears at the top-left corner of the picture, likely formed during transportation. It is recommended to optimize the packaging process." What does this mean? Inspection results can be directly converted into formal quality inspection reports. Allure 3: Powerful Generalization Capacity Traditional models can only recognize defect types seen during training; they fail to identify brand-new unseen defects. In theory, multimodal large models have processed massive images sourced from the internet, enabling them to potentially recognize all kinds of rare and irregular defects. What does this mean? Coverage for long-tail defects and abnormal edge cases is drastically improved. Allure 4: Interactive Inspection Logic Traditional solutions embed fixed inspection rules into the model. Revising inspection criteria requires full retraining. Multimodal large models support dynamic adjustment of standards via prompts. For instance, you can set the threshold as “scratches over 1cm count as NG" one day and switch it to “0.5cm" the next without modifying the underlying model. What does this mean? Tuning inspection standards becomes extremely flexible. Reading all these advantages, you may also be tempted — just as we were back then. That’s why we decided to deploy multimodal large models in several real projects, only to run into a string of costly pitfalls afterward. IV. Six Costly Pitfalls Encountered in Practical Deployment Pitfall 1: Excessive Inference Latency Unsuitable for Production Lines Our pilot project focused on appearance inspection for mobile phone housings. The production line processes one workpiece every 3 seconds, meaning total inspection latency must stay below 2 seconds to reserve 1 second for robotic sorting. We tested the GPT-4V API workflow: Upload the image and input the prompt Wait for server response Receive inspection results Average latency hit 4–6 seconds, and could exceed 10 seconds amid network fluctuations — far too slow for the assembly line. You might suggest self-hosted open-source multimodal models such as LLaVA and Qwen-VL instead. We tested these as well. Running LLaVA-13B on an A100 GPU yields single-image inference latency of roughly 800ms to 1.2 seconds. While faster than cloud APIs, it remains dozens of times slower than YOLO. Pitfall 2: Skyrocketing Throughput and Computing Costs Even if we tolerate the latency for argument’s sake, the cost calculation tells a harsh story. How many images does one production line process daily? Assuming one workpiece every 3 seconds and 20 hours of daily operation, a single line generates around 24,000 inspection images per day. For GPT-4V API, unit pricing ranged from $0.01 to $0.03 per image, depending on resolution and token consumption: Daily cost per line: $240–$720 Monthly cost per line: $7,200–$21,600 Annual cost per line: $86,400–$259,200 This only accounts for one line, while our client operated 12 production lines — an unaffordable expense for manufacturers. What about self-hosted open-source models? A single A100 GPU delivers roughly 1–2 QPS (queries per second). A single line peaks at around 0.3 QPS, seemingly manageable with one card for multiple lines. However, factoring in servers, IDC space and maintenance, the annual operating cost for an A100 deployment runs into hundreds of thousands of RMB. In contrast, a YOLO deployment only requires an edge computing box costing a few thousand RMB to support one full production line. The cost gap spans two orders of magnitude. Pitfall 3: Unstable, Probabilistic Outputs — Inconsistent Results for Identical Images This proved our most frustrating roadblock. Industrial inspection demands absolute determinism: identical images must yield identical inspection results every single time, otherwise standardized quality control and traceability become impossible. Multimodal large models, however, produce probabilistic outputs. We ran a controlled test: feeding the same defective image with an identical prompt to GPT-4V ten separate times. The outcomes varied drastically: 7 runs labeled the product defective 2 runs marked it suspected defective requiring manual review 1 run claimed no obvious defects existed All from the exact same input and prompt. Such randomness is fatal for factory quality control. Inspectors cannot act on a “70% chance of defect" output — every workpiece needs a definitive OK or NG verdict. Some propose setting temperature to 0 for consistency. We tried this method, which improved stability yet failed to guarantee 100% identical outputs. Large models generate results via sampling mechanisms, and minor deviations persist for edge cases even with temperature = 0. Pitfall 4: Fragile Prompt Engineering — Minor Wording Shifts Alter Judgments Multimodal model performance hinges entirely on prompt design, which we spent extensive manpower optimizing to boost accuracy and stability. We soon discovered prompts are extremely sensitive to wording changes. Three prompts with nearly identical core requests delivered vastly different inspection outcomes: Prompt A: “Check whether surface defects exist in this image." Prompt B: “Carefully examine the product surface and identify scratches, pits, foreign matter and other defects." Prompt C: “Act as a professional quality inspector. Locate and classify any appearance defects on the product in this image." Worse still, prompts fine-tuned for Product A lose efficacy when applied to Product B, requiring full rework of prompt logic for every new product variant. How does this differ from retraining YOLO models for new products? YOLO training relies on quantifiable evaluation metrics to clearly signal when the model meets standards; prompt tuning depends entirely on subjective trial and error, with no clear benchmark for optimal performance. Pitfall 5: Hallucination — Fabricating Non-Existent Defects with Confidence Hallucination is a well-documented flaw of large language and multimodal models: the system confidently invents details that do not exist. In industrial inspection, this manifests as three typical failures: Flagging defect-free products as defective Misstating defect positions (e.g. locating scratches on the left when they appear on the right) Misclassifying defect types (e.g. labeling pits as scratches) One test case exemplifies the severity: an entirely flawless product image triggered a highly detailed fabricated analysis: “A shallow scratch approximately 3mm long is detected at the bottom-right corner, functional impact assessment recommended." Upon close visual review, no mark or scratch was present in that region at all. If such hallucinations infiltrate mass production lines, severe consequences follow: either defective goods slip through undetected (missed inspection) or qualified products get wrongly rejected (false rejection). Pitfall 6: High Resource Barriers for Private On-Premise Deployment As cloud APIs suffer high latency and excessive cost, self-hosted deployment seems like an alternative. We evaluated hardware and software requirements for mainstream open-source multimodal models: How About YOLO? YOLOv8-m runs smoothly even on a GTX 1080 with 8GB VRAM. It can even be deployed on edge computing hardware such as NVIDIA Jetson modules with power consumption of merely tens of watts. The computational resource threshold differs by an entire order of magnitude. For most factories, installing an A100 server on the production floor is impractical in terms of both capital expenditure and daily operation & maintenance. V. Back to First Principles: What Exactly Does Industrial Visual Inspection Require? After stumbling through all the above pitfalls, we stepped back to reflect on a fundamental question: What core capabilities are essentially demanded by industrial visual inspection? Deterministic Output Identical images must yield 100% consistent results. This forms the foundation of standardized quality control and full traceability; probabilistic outputs are unacceptable. Ultra-Low Latency Millisecond-level response. Production line takt time is rigid, and inspection cannot become a bottleneck. A 10ms inference time and a 1,000ms inference time represent entirely different operational realities. High Throughput How many frames can be processed per second? How many workpieces can be inspected daily? Computational costs must remain controllable, avoiding annual expenses of hundreds of thousands of US dollars for a single production line. Edge Deployment Compatibility Factory network environments are complex; many workshops lack stable or accessible internet connections. Models must operate locally on edge devices rather than relying on cloud APIs. Interpretable Inspection Results When a defect is detected, the system needs to clearly inform inspectors of its exact location and category. Ideally, it should output defect coordinates, area and confidence scores for downstream system integration. Controllable Maintenance Costs Products get upgraded and inspection standards are revised on a regular basis. The adaptation cost for every iteration must be manageable, without full reconstruction each time. Matching these six core requirements against the two technical routes reveals a clear contrast: YOLO Series meets all six criteria perfectly Determinism: 100% consistent outputs given identical input Low latency: 10–30 millisecond inference High throughput: Dozens to over a hundred QPS per single GPU Edge-deployable: Fully compatible with Jetson hardware and industrial PCs Interpretable outputs: Bounding boxes, defect categories and confidence values Low maintenance overhead: Mature toolchains for incremental training and transfer learning Multimodal Large Models fail nearly every requirement Determinism: Inherently probabilistic output Latency constraint: Second-scale inference Throughput limit: Single GPU only supports single-digit QPS Edge deployment barrier: Demands A100-class high-end GPUs Interpretability gap: Raw natural language descriptions require secondary parsing Unpredictable maintenance: Prompt engineering lacks quantifiable optimization standards So can multimodal large models replace YOLO? The conclusion is unambiguous: At the current stage of technical maturity, multimodal large models are unsuitable as the primary solution for industrial visual inspection. Its strengths including zero-shot reasoning, deep semantic comprehension and strong generalization deliver little practical value on production lines; meanwhile its critical flaws — high latency, prohibitive costs and unstable outputs — are catastrophic for industrial quality control. VI. Not Replacement, But Complementation This does not mean multimodal large models are completely useless for industrial visual inspection. The key lies in identifying their proper niche. After two years of field trials, we have summarized four scenarios where multimodal large models create tangible value: Scenario 1: Auxiliary Automated Data Annotation Annotation constitutes the biggest cost driver of traditional inspection projects. An industrial vision task usually requires thousands to tens of thousands of annotated images. Outsourcing annotation services costs several tenths to several US dollars per frame, with labeling expenses accounting for 30%–50% of total project investment. Multimodal large models deliver pre-labeling capability: The model generates preliminary annotation masks and boxes from raw images first. Human staff only need to review and revise results instead of labeling from scratch. Our field tests prove this workflow boosts annotation efficiency by 3–5 times, cutting average labeling time per image from 30 seconds to under 10 seconds. Scenario 2: Fallback Coverage for Long-Tail Defects The performance ceiling of YOLO models is straightforward: they can only recognize defect types featured in training datasets. Unprecedented rare defects will trigger missed detection by YOLO. Although such long-tail anomalies occur infrequently, they often signal severe abnormal manufacturing conditions, carrying higher operational risks. Multimodal large models act as a fallback verification layer: When YOLO outputs a borderline confidence score (roughly 0.3–0.7, the gray zone of uncertainty), the corresponding image is sent to the multimodal model for secondary judgment. The zero-shot generalization strength of large models covers these unseen rare anomalies. Under this mechanism, only 5%–10% of all images are forwarded to the multimodal model, keeping total costs manageable while drastically improving coverage of long-tail defects. Scenario 3: Semantic Conversion of Raw Inspection Data YOLO only outputs structured data: bounding boxes, defect categories and confidence scores. While sufficient for backend industrial systems, these raw metrics are unintuitive for human inspectors, who need answers to practical questions: How severe is the defect? What caused it? What corrective action should be taken? Multimodal large models perform semantic report generation: Input: Defect coordinates, classification labels, product model and manufacturing process parameters Output: Natural language inspection report, e.g. “A 5mm scratch is detected on the left edge of the product, likely caused by mold abrasion; mold maintenance is recommended." This task is latency-insensitive (reports can be generated asynchronously) and cost-efficient (only executed on NG non-conforming products with limited volume). Scenario 4: Rapid Cold Start for Small-Sample Urgent Projects Clients occasionally face tight deadlines: new products scheduled for mass production the following week with merely dozens of defective sample images, insufficient for full YOLO training. Traditional workflow cannot launch inspection under such limited data. Multimodal large models serve as a transitional temporary solution: Zero-shot capability enables immediate deployment with acceptable yet imperfect accuracy, far outperforming full manual inspection. Data can be continuously collected during pilot operation to train a formal YOLO model for long-term use once sufficient samples are accumulated. VII. Hybrid Architecture: Our Practical Deployment Paradigm Based on the above analysis, we have adopted a hybrid dual-channel architecture for recent industrial projects: Main Inspection Channel: YOLO Handles over 95% of all inspection workloads Deployed locally on edge hardware with 10–20ms inference latency Outputs structured bounding boxes, defect types and confidence scores Auxiliary Channel: Multimodal Large Model Only processes borderline low-confidence images within the gray zone Invoked asynchronously without disrupting main line throughput Functions for long-tail defect fallback verification, semantic report generation and auxiliary labeling Core design principles of this hybrid framework: YOLO acts as the core primary system; multimodal models serve as auxiliary tools — avoid reversing their roles Data shunting instead of serial processing: multimodal models stay off the critical production path and impose no impact on main-line latency or throughput Confidence-based traffic splitting: high-confidence results pass through directly, while ambiguous samples are forwarded for secondary multimodal validation Predictable cost control: only a small fraction of images consumes multimodal model computing resources VIII.
