Paper Abstract

At present, most of the pantograph slide images used for slides wear detection based on the image processing are obtained by using overhead mode, but this way has some limitations for some complex arched., The purpose of this study based on the yang-shot mode is to build detection system about slides wear. Firstly, 2 CCD cameras shoot the pantograph slide images, and they are transmitted and stored in the host detection by video capture card. Then the edges of saving image are detected, and the edges of pantograph slides and contact wire are located. The result showed that in this way, we can obtain the simple background and high contrast gradient of images. It is easy to detect edges, and to provide the significant data for detecting the pantograph slides wear volume of the remaining.
