| Abstract: | Contour extraction and the key point selection of the rail cross-section were mainly discussed. Con-tour extraction was realized by using power transformation nonlinear operation to pixel. Location of cross-sec-tion image initiation point and thinning of contour line met the requirement of accuracy and speed. |
