摘要： 为提高目标定位精度，研究了多站交会大尺寸精密测量系统中传感器布站优化方法。首先，以电子经纬仪为例创建了多站交会测量系统基于传感器误差分离的优化布站数学模型；然后，分析了测量空间内的布站约束条件并对之进行了几何近似；最后，利用郭涛算法求解带有约束的非线性规划问题，得到布站空间内传感器最佳位置组合。仿真分析结果表明，该方法能够有效提高系统测量精度，可应用于多站交会测量现场布站过程。

Abstract: In order to improve the positioning precision of the target, an optimal disposition method for multiple sensors intersection system for large scale precision measurement is researched. Taking electronic theodolites as an example, a mathematical optimal disposition model for multiple sensors based on error separation is presented firstly, then the spatial constraints of the sensor disposition are analyzed with geometric approximation algorithm, the question of non-linear programming with inequality constraint conditions is solved by Guo algorithm and the best disposition of the sensors in permitted space is attained at last. The result indicates that the precision of the measurement is improved evidently and it can be use to provide guidance for disposition of multiple sensors in industrial field.

Key words: Large scale measurement, Optimal disposition, Error separation, Spatial constraints, Guo algorithm
