摘　　要：设计了一套粗糙表面精度测量系统,采用线边缘激光三角法实现了亚像素级测量,在图像算法上采用改进的阈值法进行边缘检测,用形态滤波法对被测物表面图像进行处理。研究结果表明,该系统能较好地提高测量精度,并得出较满意的图像边缘,可达到5 m的测量精度要求,且具有一定的通用性,实现了对具有粗糙表面的电池极片涂敷层的厚度及均匀性的测量。A system for measuring rough surface accuracy was designed. A line edge laser trianglulation method was used to realize subpixed measurement and a threshold value method was utilized to improved measuring image algorithms. At the same time, a morphological filtering was used to process the surface image of a quizzee. The results show that the system can improve the accuracy better and obtain the satisfied image ledge and the accuracy survey of 5 m. The measurement system can be used in a wide scope and can also realize the measurement of the thickness and uniformity of coating layer on battery electrodes with rough surface.
