将图像处理算法引入机车受电弓滑板的磨耗检测中，提出一种检测受电弓滑板实际厚度的测量算法。由于直接对图像进行边缘检测易受噪声、光照等因素影响，通过Hough变换对图像进行水平校正，由模糊聚类算法进行图像分割以去除光照不均及噪声的干扰，对分割后图像采用Canny算子精确提取滑板的边缘信息。考虑提取边缘的不连续性，引入结合数学形态学的边缘生长方法实现不连续边缘的连接，通过图像标定计算出实际滑板磨耗厚度。
將圖像處理算法引入機車受電弓滑闆的磨耗檢測中，提齣一種檢測受電弓滑闆實際厚度的測量算法。由于直接對圖像進行邊緣檢測易受譟聲、光照等因素影響，通過Hough變換對圖像進行水平校正，由模糊聚類算法進行圖像分割以去除光照不均及譟聲的榦擾，對分割後圖像採用Canny算子精確提取滑闆的邊緣信息。攷慮提取邊緣的不連續性，引入結閤數學形態學的邊緣生長方法實現不連續邊緣的連接，通過圖像標定計算齣實際滑闆磨耗厚度。

The image processing algorithms are introduced in the abrasion detection of locomotive pantograph slide, and a combined method is proposed to detect the actual thickness of pantograph slide. The edge detection for images is always susceptible to noise, uneven illumination and other factors. The Hough transform is employed for image horizontal correc-tion. To reduce the influence of noise and uneven illumination, the fuzzy clustering algorithm is used to segment image, and the segmented image is edge-detected by Canny operator to extract the edge information of pantograph slide. Because the extracted edges are of discontinuity, an edge growing method combined with morphology is used to connect the dis-continuous lines. The edge lines are calibrated to calculate the abrasion of pantograph slide.
