AI Technical Summary
Existing enameled wire coating inspection technologies suffer from spectral distortion and large thickness calculation errors when inspecting cylindrical surfaces, making it difficult to achieve high-precision circumferential thickness distribution detection.
By employing geometric distortion correction based on the radius of curvature and the cylindrical surface interference optical path difference model, combined with frequency domain analysis and information entropy mining, high-precision detection of paint film thickness distribution and defect identification are achieved through spectral data processing and phase demodulation.
It improves the accuracy of paint film coating inspection and the reliability of defect diagnosis, and can accurately distinguish between periodic eccentric and discrete random defects, significantly improving the accuracy and reliability of inspection.
