Abstract

Edge detection is a key technique for detecting foreign objects intrusion on railway rails. For the problem of poor detection of rail image edge, a rail edge detection extraction scheme based on Canny edge detection technology and convergence connection method is proposed in this paper. Through the histogram equalization, the spatial enhancement of original image is achieved, and the details of the image are highlighted, the edge combination of the image is extracted through the Canny edge detection, and the longest two lines in the edge combination satisfying the conditions are extracted by using the convergent continuation method proposed in this paper, and continue to implement it, which can achieve the purpose of rail edge extraction.
