摘　　要：通过机器视觉技术设计一种可同时检测圆形工件多角度的在线视觉检测系统,根据等腰直角棱镜的光线折射、反射特性,计算光线入射角与棱镜出射角关系式,并求出光源与棱镜的安装角度关系,入射光线与棱镜表面的呈现角度,设计一套视觉检测结构,并计算各检测尺寸值与原尺寸值的关系式。该系统可应用于全自动螺栓视觉筛选机,实现螺栓快速稳定检测。This paper,based on machine vision technology,designs an on-line visual inspection system for testing multi angles of circular workpiece.According to the refraction and reflection characteristics of the isosceles right angle prism,the relation between the incident angle of light and the angle of the prism exit is calculated,and the relation between the light source and the prism is calculated.The incident light is 105 degrees to the prism surface.A visual inspection structure is designed,and the relationship between the measured size values and the original size values is calculated.This system is applied to the automatic bolt visual screening machine,the rapid and stable bolt detection is realized.
