摘　　要：针对传统齿轮检测系统无法定量检测齿轮齿顶圆精度,采用数字图像处理技术提出一种齿顶圆检测系统方案。该方案通过利用图像边缘提取和最小二乘法拟合等技术,计算所提出的误差评判参数的数值,并以此定量评判齿顶圆精度。通过实验验证,该方案最终可以定量测量齿顶圆精度,且误差在可接受范围内。In view of the problem that the traditional gear detection system cannot detect gear tooth top round quantitatively, this paper adopted digital image processing technology to realize an addendum circle detection system. The image edge extraction and least square fitting technique can quantitatively evaluate the addendum circle accuracy by the error parameters proposed in this paper. Through experiment verification, this scheme can quantitatively measure addendum circle and make the error in the acceptable range.
