| 摘 要： | 在使用光测网对运动目标进行多站定位时，由于受到诸多干扰因素的影响，定位点的测量值并不唯一，从而影响目标定位的精度。提出一种新的迭代初始值——公垂线中点。为了进一步提高估计精度，结合多站最小二乘交汇定位法对目标定位，并对各测站的测量角量做了残余系统误差的最小二乘修正。最后，还给出一个随机模拟实例以验证所提算法的可行性。 |

| Abstract: | When using optical measurement system network to give the position of a moving aim, people often obtain many measure results because of many interferential factors. Therefore, it reduces the precision of measure. We suppose a new recursive initial value. In order to improve the precision of estimation, the least-squares multi-observation station method is used to determine the position of the observation. We also correct the residual error in order to improve the measure precision. Finally, a simulation example is given to test the feasibility of our method. |
| Keywords: | optical measurement system network the measure of multi-observation station least-squares method residual error |
