摘　　要：针对齿条接触式测量,提出了一种基于机器视觉的小模数齿条测量方法,建立了一种机器视觉的测量系统。该系统通过光栅控制齿条的运动,同时,CCD摄像机对齿条进行拍照以实现全齿测量。运用Matlab软件分析处理采集到的图像,得到齿条的边缘。计算齿条的基本参数(齿距p、齿厚s等)数据,评定齿条的相关参数。此方法实现非接触测量,采用机器视觉测量方法实现了齿条参数的测量,为齿条的在线测量提供了保障。Aimed at rack contact measurement, a method of small-module rack measurement based on machine vision is proposed. A machine vision measurement system is established. The system controls the movement of the rack with the grating,while the CCD is taking photos of the rack to realize the measurement for the whole rack. The images is analyzed by Matlab, and the edge of the rack is obtained. The basic parameters of the rack such as p and s,assessment of parameters related to the rack is calculated. The experiment turns out that the precision of this method can meet the requirements for the measurement of such rack, providing technical support for the rack online testing.
