摘　　要：视觉测量技术作为现代精密测试行业中最具前景的高新技术之一,已经广泛应用于现代化制造生产中,满足大部分自动化生产的需求,并极大地提高了生产效率.地铁盾构混凝土管片是一种高精度的预制混凝土构件,使用大型游标卡尺测量管片宽度,或者用钢卷尺测量弧长,都无法满足其高精度尺寸的要求.本研究介绍一种基于计算机视觉的非接触测量的原理与测量过程、应用效果,可应用于地铁盾构混凝土管片测量,简便、灵活、精度高,传感器系统的极限误差和稳定性分别为0.10 mm和0.05 m,符合要求.As one of the most promising high and new technologies in modern precision testing industry,vision measurement technology has been widely used in modern manufacturing production,meeting the needs of most automatic production,and greatly improving production efficiency.Metro shield concrete segment is a kind of high-precision prefabricated concrete component.Using large vernier caliper to measure segment width,or using steel tape to measure arc length,can not meet the requirements of its high-precision size.This paper introduces a non-contact measurement method based on computer vision.The method is simple and flexible,and the limit error and stability are 0.1 mm and 0.05 m,respectively,which meets are requirements.
