【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。
[Abstract]:The structure of the ring is quite complex, the manual inspection procedure is cumbersome, and the current automated machine vision inspection system has fatal defects in the high-precision inspection of the large ring, which is due to the larger radius of the ring and the larger photographing area.Even the area array camera with high pixel can not meet the requirement of high precision.Aiming at the difficult problem of tooth shape detection, the machine vision detection system is to study the defect characteristics of gear ring tooth pitch, tooth height and oblique tooth in depth, and develop a set of machine vision detection algorithm with high accuracy by using Delphi software development tool.By using linear array camera and linear scanning method, the defect of tooth shape and the corresponding size of large synchronizer gear ring can be detected quickly and effectively. It has very important practical value in today's high demand for gear ring.
