光雷一体化测量系统的布站优化研究

The Research of Optimization Model for Photoelectric Theodolite with Radar Station Distribution

光雷一体化测量系统具有测角和测距两种功能,它可以实现对目标的单站定位,也可以实现两站交会测量,因此,该类系统布站时必须同时考虑多种测量方式。针对这个问题,提出基于测量模型及其精度分析的布站优化方法。即在覆盖弹道的合理的长方形区域内,以网格形式得到预选的布站点位,并利用提出的布站优化方法,得到单站或两站的最优布站。使得该布站条件下各种测量方式的精度均值在给定范围内,方差最小。

Because of measuring both angle and distance,the photoelectric theodolite with radar can provide mono-station location and two station intersection,many measurement methods must be considered when placed measurement systems.The optimization model is proposed for station distribution of the photoelectric theodolite with radar based on measure model and precision analysis.The optimum station distribution can be gained for the single measurement system or two measurement systems from the preselected sites in reasonable rectangle area which covered trajectory,by using the proposed station method,and,the variance of measure accuracy is minimum and its mean is in the small range.
