摘　　要：活塞作为活塞式空压机的主要零部件,对其加工精度的要求相当高,其加工误差直接影响空压机的运动性能、工作寿命。对非接触式数字图像检测方法进行研究,提出基于复合Canny算子的图像边缘检测算法,并进行运算分析。结果表明该方法可行,能够取得良好的检测效果。As the main components of piston air compressor, the precision requirement of piston is very high. The processing er- ror of piston directly impacts movement performance and working life of air compressor. Through analyzing non-contact digital image detection method, an image edge detection method based on composite Canny algorithm was put forward, and computation and analysis were made. The results show that this method is feasible and can achieve good test effect.
