Computer Vision

Definition

Computer Vision is an AI technology that acquires, processes, and analyzes digital images to extract high-dimensional data from the real world and transforms it into numerical or symbolic information for decision-making. The key is not simply storing images captured by cameras, but enabling computers to 'understand' the meaning within them and elicit appropriate actions.

Applications in Manufacturing

Quality Inspection Automation

• Surface defect detection: Real-time identification of scratches, dents, and foreign materials on product surfaces
• Dimensional measurement: Non-contact inspection of precise part dimensions for automatic defect sorting
• Assembly verification: Automatic confirmation of missing parts or incorrect assembly

Process Monitoring

• Worker safety management: Detection of hazardous zone entry and missing protective equipment
• Material tracking: Automatic tracking of parts and finished goods movement
• Equipment condition monitoring: Early detection of abnormal signs like equipment overheating using thermal cameras

Robot Vision

• Bin picking: Robots recognize and pick randomly stacked parts
• Welding/bonding guidance: Real-time identification of precise locations on non-standard workpieces

Key Points

In manufacturing, computer vision is a critical tool that simultaneously achieves 24/7 consistent quality standards, faster inspection speeds, and labor cost reduction. Deep learning-based vision systems can detect even microscopic defects that were difficult to find with traditional rule-based methods through learning, making it an essential technology in precision manufacturing sectors such as semiconductors, displays, and automotive industries.
