室内空间测量定位系统是基于光平面交会原理的大尺寸分布式坐标测量系统，具备大量程、高精度、多任务并行、全空间实时测量等特点，应用广泛。该测量系统在测量过程中需要在空间不同位置放置多个发射站同时工作，而发射站在空间的不同布局对测量精度有着较大影响。为得到一种较好的布局，研究发射站光平面在测量点的不同交会方式对测量稳定性的影响，推导建立数学模型，以此来评价布局的优劣。在此数学模型基础上设计遗传算法来求解较优布局，并对实际测量中常用的两站到四站的测量系统进行优化仿真研究。仿真结果表明在给定测量条件下，利用此数学模型设计的算法可以优化布站，得到一种较好的空间布局，提高测量稳定性。

Indoor workspace measurement and positioning system is a type of distributed large-scale measurement system based on the intersection of optical planes. This measurement system is widely used as it has advantages of large range, high precision, multitasking and whole space real-time measurement. Transmitters are needed to be placed at different positions of the workspace in the measuring process. So, the station deployment has a great influence on the measurement accuracy. To get a better layout, the relations between different intersection way of optical planes in measurement point and the stability of the measurement are analyzed. And a mathematical model is established. Then the genetic algorithm based on the mathematical model is designed, furthermore, the deployments of two to four stations are simulated and analyzed. The simulation results show that this method can optimize station deployment and give an optimal layout to improve the measurement stability of different measuring conditions.
