AI Technical Summary
Existing corrugated pipe surface defect detection technologies cannot effectively distinguish between cracks and pores, and have insufficient ability to identify bubble defects, resulting in a high false judgment rate and failing to meet the inspection needs of mass production lines.
By combining tracer gas color detection, ultrasonic detection, and image morphology analysis, a closed-loop judgment system with multiple features and verifications is constructed through color feature extraction, ultrasonic signal processing, and image processing. Combined with directional air blowing verification, accurate identification of defects on the surface of corrugated pipes is achieved.
It enables accurate differentiation of cracks, pinholes, and bubbles, reduces the false positive rate, improves the reliability and efficiency of detection, and meets the needs of batch production line inspection.
