摘　　要：为了使机器视觉技术能广泛、可靠地用于零件尺寸测量,并保证测量数据的精度和稳定性要求,以CMOS相机、光学镜头、平行光源等为核心硬件,搭建并开发出一套基于机器视觉的尺寸测量系统。运用该系统对标准块规进行了重复精度、线性度、系统稳定性及环境光源影响等方面的实验研究。试验数据表明:该系统在所测尺寸变化较小的情况下,具备良好的测量精度与稳定性能,测量精度能够达到0.005 mm。In order to make the computer vision technology for comprehensive, reliable measurement of part size, and to ensure the accuracy and stability of the measurement data requirements. In this paper, CMOS camera, opti- cal lens, parallel light source, such as the core hardware, build and develop a set of dimensional measurement sys- tem based on computer vision. The experimental analysis of repeatable accuracy, linearity, system stability and am- bient light effects by using the measuring system to standard gauge block shows that measuring system has the high accuracy of measurement, which can reach 0.005 mm precision measurement requirements, in the case of small size transform range.
