Rail Track Edge Detection Methods Based on Improved Hough Transform

In order to ensure the safety of train operation, it is necessary to strengthen the real-time monitoring of train operation environment. This paper use improved Hough transform to detect the rail track edge. First, detect the edge of the image use Canny operator. Second, find the lines among the edge image. Third, find longest lines as the outlines. Matlab simulation is used to detect the collected image. Experimental results show that this detection method can get a good result.
