1. High precision: The detection accuracy can reach micrometer level (such as 0.01mm), far exceeding manual visual inspection (usually only millimeter level); 2. High speed: Single frame detection time can be as low as milliseconds, suitable for high-speed production lines (such as detecting hundreds of parts per minute); 3. Non contact: Avoid damage to objects (such as appearance parts and precision electronic components) during the detection process; 4. Strong stability: not affected by artificial fatigue or emotions, with unified testing standards and traceable data; 5. Scalability: Upgrade the detection types through algorithm upgrades (such as adding defect type recognition).
