摘　　要：介绍了国内大型轴承测量技术现状和光笔测量系统的结构及测量原理。针对采集到的光笔图像提出图像线性变换预处理、改进的中值滤波去噪处理、图像开闭运算处理及发光点图像特征提取处理的方法。实际验证该算法简单有效,图像处理准确性高,在3 200 mm范围内直线方向上的累计误差为1.6 mm,能满足大型轴承测量要求。The measurement technology situation of the domestic large size bearing and the structure and measurement principle of light pen measurement system are introduced. Aimed at the captured light pen images, the method are put forward for image linear transformation pretreatment, improved median filtering de - noising treatment, open and close operations of image processing and luminous point image feature extraction treatment. The method is proved to be sim- ple and effective with high accuracy of image processing through the experiment, the cumulative error on a straight line within 3 200mm is 1.6 mm, which is able to meet the requirements of large scale bearing measurement.
