| 摘 要： | 四路激光跟踪三维坐标测量系统的测量精度在很大程度上取决于四路干涉仪的布局。系统地研究了四路激光跟踪三维坐标测量系统的布局优化问题,以被测点的位置几何精度衰减因子(PDOP)最小为目标进行优化,得到了三种系统最佳测量布局。考虑到系统自标定对布局的要求以及目标靶镜接收角范围的限制,得到了一种具有实用价值的系统最佳布局。

| Abstract: | The measuring accuracy of four-beam laser tracking system for 3D coordinate measurement in large degree depends on the arrangement of the interferometers. In this paper the arrangement of four laser tracking interferometers is discussed and three kinds of the optimal arrangements of four laser tracking interferometers are obtained through minimizing the position dilution of precision of the measured point. One of those arrangements of four laser tracking interferometers is considered as the most reasonable arrangement according to the limited receiving angle of the cat's-eye and the restriction on the arrangement in the process of system self-calibration. |
