摘　　要：针对某联轴器厂的产品检测需求,设计一种尺寸测量系统,该系统结合机器视觉技术,主要由照明系统、图像采集系统、计算机视觉系统组成。利用HALCON软件中的标定助手进行系统标定,通过创建二维计量模型实现联轴器中心孔的测量功能,采用模板匹配和仿射变换实现对不同位置、角度的联轴器中心孔尺寸的测量。A dimension measurement system based on machine vision technology is designed to meet the product inspection requirement of a coupling factory,the system mainly consists of lighting system,image acquisition system and computer vision system.Calibration assistant function in HALCON software is used for system calibration,the two-dimensional measurement model is established to realize the measurement of the center bore of the coupling,and measurements of center bore of the coupling from different positions and angles are realized by template matching and affine transformation.
