| 摘 要： | 研究了系统最佳布局下的最佳测量区域问题,给出了几何精度衰减因子PDOP在三维空间内的变化规律。通过计算机仿真研究了最佳测量布局对系统自标定的影响规律,指出最佳测量布局中的标称配置对系统自标定精度的影响最小,同时这种布局有着最小的几何精度衰减因子。

| Abstract: | The optimal measuring zone under the optimal arrangement of four laser tracking interferometers is discussed, and the distribution of PDOP of the measuring points in 3D space is also given. The relationship between system arrangement and the self-calibration is also studied by using of computer simulation. The results show that the nominal setup of all the optimal measuring arrangements plays the least role in the process of the system self-calibration and has the minimal value of PDOP of the measuring points. So, it is finally reached out that the nominal setup is just the optimal arrangement of the whole system. |
