摘　　要：为满足城轨列车受电弓滑板磨耗病害的自动化检测需求,提高受电弓滑板磨耗病害检测效率,设计了一种基于机器视觉的受电弓滑板磨耗检测系统,应用改进型Canny边缘检测算法,获取受电弓滑板边缘图像,通过霍夫变换等技术,提取与拟合滑板磨耗边缘,获取滑板的磨耗信息,然后分析判断磨耗数据,最终实现对弓网磨耗情况的非接触式精准自动检测。结果表明,在正向平行拍摄角度下,系统测量结果与人工测量结果高度吻合,准确率达到91.6%,可满足实际检修需求。In order to meet the automation detection requirements for the wear and tear of pantograph slide plates on urban rail trains and improve the detection efficiency of pantograph slide plate wear and tear,a machine vision based wear and tear detection system for pantograph slide plates is designed.The improved Canny edge detection algorithm is applied to obtain the edge image of the pantograph slide plate.Through techniques such as Hough transform,the wear and tear edge of the slide plate is extracted and fitted,and the wear information of the slide plate is obtained.Then,the wear data is analyzed and judged,and finally,non-contact accurate automatic detection of pantograph mesh wear is achieved.The results show that under the forward parallel shooting angle,the system measurement results are highly consistent with the manual measurement results,with an accuracy rate of 91.6%,which can meet the actual maintenance needs.
