Research on the real-time monitoring system for the cable surface defects based on the photoelectric detection technology

Abstract： A real-time detection system for cable surface defects was designed based on the photoelectric detection technology. In its hardware, the linear CCD camera and the arc-shaped LED white lights were selected to take the cable images. In its software, an improved ROI(Region of Interest) algorithm was proposed to locate the cable surface defect, a novel image difference algorithm based on the improved bilateral filtering algorithm was employed to build the background model, and an adaptive filtering window algorithm based on the CV-Kmeans region classification was improved to highlight the cable defect features. The obtained results show that the developed detection system for cable surface defects has high recognition ability, and the overall monitoring accuracy is not less than 97.0%.
