摘要
本文介绍一种利用多种亚像素图像技术提取目标及网格节点，并采用新的摄影系统标定与系统误差修正技术，用多个摄像机实现对有特殊标志的空间三维运动目标的高精度测量方法。
A high accuracy measurement method for a 3D moving object with specified marks is presented in this paper.Several subpixel image processing algorithms are used to derive the object posion and grating intersections.A new camera calibration and correction method is introduced and used.With these techniques,the 3D movement of objects is measured accurately with multicamera system.
