Wiring harness assembly detection system based on image processing technology

Describes a image processing based wiring harness assembly technique detection system. Real-time collection on detected harness´s color, location and other information by image processing, to determine whether the errors mounted harness by image processing software. First through the spatial filter method, using the median filter to eliminate noise and interference of the collected images in order to obtain a clear picture. Then using Otsu method for image thresholding, and Sobel operator to detect edge to determine the wiring harness of the exact location in the image. Finally, use color matching algorithm to match and compare the image to finalize the wiring harness eligibility. Testing accuracy of the system has greatly improved than the previous manual detection. Improving test efficiency, product quality and productivity.
