摘　　要： 齿环的结构比较复杂,手工检测齿形程序繁琐,目前的自动化机器视觉检测系统在大型齿环高精度检测方面存在致命的缺陷,这是由于齿环半径较大,拍照区域也较大,即便是高像素的面阵相机在这种情况下的检测精度也会显著降低,不能满足高精度的要求。针对这个齿形检测的难题,该机器视觉检测系统是对齿环齿距、齿高、斜齿等缺陷特征进行深入研究,利用Delphi软件开发工具,开发出一套高精度识别缺陷的机器视觉检测算法,通过使用线阵相机和线扫描齿形区域的方法,能够快速有效的检测大型同步器齿环的齿形缺陷及对应尺寸,在对齿环需求量较大的今天,有着非常重要的实用价值。 The structure of the tooth ring is complex and there have a large problem in the detection of tooth pitch and oblique tooth defect, especially for big gear ring. Due to large gear ring radius, photo area is bigger also, even the high pixel array camera in this case will be significantly reduced the accuracy, so cannot satisfy the requirement of high precision. For this problem, we research on the characteristics of tooth pitch, tooth height and oblique, based on Delphi program tools, using linear array camera and the method for line scanning tooth shape region, developed a set of high precision machine vision detection algorithm, this program can quickly and effectively detecting the tooth shape detection. The demand for gear ring is larger now, so it has very important practical value.
