摘　　要：将数字图像处理技术应用于受电弓故障监测,提出一种新型的窗口边缘跟踪算法,在采用Canny算子计算出边缘二值图的基础上,设置适当大小的窗口对初始不连续边缘进行遍历,估计断点处边缘点位置获得连续边缘,并采用最小二乘法拟和出连续平滑的曲线函数。该算法灵活多变,针对不同的曲线可通过调节窗口参数获得较好的跟踪效果,且经过曲线拟和可达到亚像素精度。Digital image process technique is used in pantographic faults monitoring,and a new algorithm named window-edge tracking is proposed in this paper. Based on the binary image of edges which is detected by Canny operator,a window in proper size is set to track the discontinuous edges to estimate the position of the lost edges. With this method continuous edges will be obtained,and continuous and smooth edges will be got after least-squares curve-fitting. Through adjusting the parameters of the window,the pref...
