多视点三维测量系统的全局标定方法研究

针对线结构光三维测量速度较慢和易发生遮挡问题，开发了一种多视点线结构光三维测量系统．并针对本系统提出了一种简易的基于线结构光的多目视觉三维测量系统全局标定方法，标定过程只需要一块可自由移动的共面靶标，即可将所有摄像机局部坐标系统一到光平面测量坐标系，实现多视点测量数据的自动拼接．实验表明，该方法方便易行，适合现场标定，同时满足系统精度要求．

A Global Calibration Method for Multi-camera 3D Measure System

A multi-camera 3D measure system based on line structured-light was presented to overcome the problem of slow measuring velocity and occlusion. A facilitated global calibration method for the system was proposed. With only a coplanar reference target that is free to move, multiple camera reference frames can be transformed to the optical plane measurement reference frame to realize 3D data registration from different views. The experimental results show that the method is practical in multi-camera 3D measure system.
