The applications of machine vision can be categorized into defect detection, guidance, dimensional measurement and identification. These applications primarily assist in improving product quality, production efficiency and optimizing manufacturing processes in the industrial domain.
By leveraging steps such as image acquisition, image processing, feature extraction, object recognition and decision-making, machine vision systems excel at tasks like surface defect detection, product tracking and verifying object shapes or designs to ensure traceability and quality control. Machine vision can guide or assist robots for precise actions and perform dimensional measurements to guarantee product consistency and accuracy.
The technological architecture of machine vision includes lighting, industrial cameras and software. Depending on the application scenario, it can incorporate components like motion control, frame grabbers and AI accelerators. An industrial PC or embedded system forms the core of the machine vision system, managing and processing operations. The system uses industrial cameras and lighting for image acquisition, with software controlling hardware for image processing, analysis and decision-making. Additional components such as motion control and AI accelerators enhance precision and efficiency in diverse applications.
In modern manufacturing, quality inspection is a critical component of competitiveness. Visual inspections are prone to inefficiency and high error rates due to fatigue over extended periods. This inefficiency is particularly problematic on fast-moving production lines where manual inspections often fail to keep pace, delaying production.
The introduction of machine vision systems integrated with AI has significantly optimized defect detection on production lines. These systems:
Case Study:
Edge AI precisely analyzes images, reducing false positives and missed defects, ultimately lowering defect rates.
Processes images instantaneously, allowing quick identification of defects and preventing defective products from advancing.
Automation minimizes human involvement in quality inspection.
Maintains consistent quality control even in high-speed production environments.
Records inspection data for process improvement, enabling manufacturers to identify common defects and improve quality further.
Infrared light grids are commonly used in industrial safety monitoring to detect objects or personnel entering hazardous zones. However, they provide limited information, such as merely determining proximity, without offering details like object shape, size or material.
Machine vision-based smart cameras integrate the functionalities of a camera, industrial PC and software, offering advantages over traditional systems, including:
Smart cameras significantly improve overall safety monitoring efficiency, thanks to their adaptability, advanced analysis capabilities and cost-effective integration.
