摘　　要：基于双目立体视觉传感器三维测量模型和空间坐标变换原理,采用最小二乘冗余算法,讨论了双摄像机测量空间三维点坐标的基本原理,建立了视觉测量系统的非线性测量方程。通过实验验证了双摄像机光笔式三维坐标视觉测量系统建立的可行性。In this paper, based on the binocular stereo vision sensor 3D measurement model and the principle of coordinate transformation of space and adopting the least square redundant algorithm, the basic principle of the measuremant of the space 3D point coordinate by the two-camera is discussed. The non-linear measurement equation of the visual measuring system is establishea. Through experiment, the feasibility of the Two-light pen-camera visual 3D coordinate measuring system is proved.
