| Abstract:The rail expends under the action of running load and natural factors and thus produces longitudinal displacement, which affects the locomotive running safety. Therefore, it is of great significance to develop high-performance rail longitudinal displacement detection device. For rail displacement detection device time-consuming, caused by artificial detection method of problem, based on the MATLAB simulation, design a rail longitudinal displacement detection system based on image processing algorithm, this paper discusses the sampling image preprocessing, binarization, Canny edge detection, Hough transform and the longitudinal displacement calculation algorithm implementation process. The experimental results show that the designed system has high accuracy and can meet the practical needs of engineering. |
