Qu'est-ce que la vision industrielle ? Guide des systèmes d'inspection par caméra

What Is Machine Vision?

Machine vision is an automated inspection technology that uses one or more industrial cameras, lighting, and image processing software to perform quality inspection tasks on a production line, faster, more consistently, and more objectively than human visual inspection.

Core Components of a Machine Vision System

• Industrial camera, area scan, line scan, or 3D sensor capturing images of the product or component
• Lens and lighting, controlled illumination to highlight features of interest (defects, print, dimensions)
• Vision processing computer, industrial PC running image processing algorithms (OpenCV, Halcon, MVTec, or custom deep learning models)
• I/O interface, triggers camera from production line encoder; sends pass/fail signal to PLC for reject mechanism

What Can Machine Vision Inspect?

• Surface defect detection, scratches, dents, cracks, contamination
• Dimensional measurement, part size, hole diameter, gap measurement
• Label and print verification, text, barcode, QR code, date code reading
• Presence/absence, verify all components are assembled correctly
• Colour inspection, correct colour, colour uniformity

Hardware for Machine Vision

Machine vision demands a high-performance industrial PC with fast CPU, GPU acceleration (for deep learning models), and multiple GigE camera ports. Avalue AI Box PCs are purpose-configured for multi-camera vision systems, available from TSL Automation Solutions. Contact us to configure a vision system compute platform.
