AI Technical Summary

Technical Problem

In existing technologies, in detection scenarios where multiple defects coexist, the repeated switching of light sources and repeated image acquisition lead to low detection efficiency, which cannot meet the detection requirements of high-speed production lines.

Method used

Synchronous illumination is achieved by using monochromatic light sources with different center wavelengths. A single image is acquired by a color camera and processed by channel separation to extract the channel component images corresponding to each monochromatic light source, thus obtaining imaging results under multiple illumination fields with a single illumination.

Benefits of technology

Significantly shortens the imaging and inspection cycle, improves inspection efficiency, adapts to the needs of high-speed production lines, reduces the frequency of mechanical component movement, lowers equipment failure rate, and ensures the reliability and consistency of inspection results.
