摘　　要：介绍了曲面点磨削的工作过程 ,设计出针对砂轮磨损状况的CCD动态监控系统 ,利用CCD摄像机对砂轮磨削点处进行实时图像采集。利用亚像素边缘定位算法 ,对砂轮图像进行轮廓提取 ,并与理论轮廓进行比较。实验结果表明 ,CCD动态监控砂轮磨削状态的方法是非常有效的 ,而且检测精度也比较高 。The working process of point grinding on curve surface was presented. CCD online monitoring system was developed, the images of grinding area can be gathered in real time by using CCD camera. A location algorithm of subpixel edge is studied. The outline edge of grinding wheel can be extracted with the algorithm, and the detected result is compared with the perfect outline. We can see from the experimental result that the method of by using monitoring grinding by using is valid. Detection precision and results are reasonable.
