基于改进Radon变换的直线钢轨识别算法
Linear Rail Recognition Algorithm Based on Improved Radon Transform
摘要
Abstract
Because of the slow detection speed and the failure of the tradition Radon transform to recognize the rail from multi edge lines, a new and improved method is proposed based on Radon transform.Firstly, edge points are selected based on threshold;secondly, prior knowledge is used to establish a polar angle constraint area;thirdly the Radon transform is employed to extract edge lines;then the angle difference and average distance are utilized to identify the edge line of the rail;finally, the algorithm is compared with the traditional algorithm Hough transform and traditional Radon transform algorithm.The experiment results show that improved Radon algorithm is faster and accurate in recognizing the rail.关键词
