| Abstract: | Since the current method for measuring the slope of catenary localizer is inefficient and inaccurate,the method for automatically measuring the slope of catenary localizer based on computer vision was studied.The collected images of catenary localizer were processed by applying such algorithms as image segmentation,interfering line elimination and image thinning,etc.Then an improved Hough transform was adopted to detect the thinned images,and the neighbored feature pixels in the image were clustered and per... |
