AI Technical Summary

Technical Problem

Traditional visual inspection equipment is difficult to adapt to the inspection needs of various metal workpiece types and defects, and lacks intelligent adjustment mechanisms, which leads to the determination of inspection parameters relying on human experience and low detection rate of weakly significant defects.

Method used

The system employs a vertically arranged first and second arc-shaped track mechanism, combined with a deep neural network angle decision model, to automatically adjust the camera and light source angles. It matches the optimal detection parameters through a storage module and uses a multi-angle fusion imaging strategy to identify defects.

Benefits of technology

It enables rapid adaptation to multi-variety, small-batch testing, improves the flexibility and accuracy of the testing system, significantly increases the detection rate of weakly significant defects, and reduces the need for manual adjustments.
