工作空间测量定位系统(workspace Measuring and Positioning System,w MPS)是一种基于旋转激光扫描平面交会的室内大尺寸定位系统。它可实现计量精度的三维坐标测量,主要应用于制造加工及装配领域的测量和检测任务。作为一种大尺寸的测量系统,与中小尺寸测量系统相比,它的测量空间与测量精度的矛盾更加突出。如何寻找此系统所覆盖测量空间内精度最高的一个点或者以此点为中心的一个区域是一个非常重要而且有意义的问题。从该测量系统的测量原理出发,与传统经纬仪相对比,给出一种利用解算方程系数矩阵的条件数作为评价空间交会优劣的评价模型,继而引入粒子群算法来求解测量空间内的最佳测量点,实验结果表明:评价模型和对应的求解方法是正确的,也是有效的,利用此方法得到的测量点为中心的区域坐标不确定度最小,而且此方法为今后的发射站布局问题的研究打下了有益的基础。
The workspace measurement and positioning system (wMPS) is a large indoor positioning system based on a rotating laser scanning plane intersection. It can achieve measurement accuracy of the three-dimensional coordinate measurement, mainly used in manufacturing and assembly of the field of measurement and testing tasks. As a large-scale measurement system, compared with small and medium size measurement system, its measurement space and measurement accuracy of the more prominent conflict. It is a very important and significant issue how to find a point with the highest accuracy or a region centered around this measurement space covered by this system. Starting from the measuring principle of this measuring system, compared with the traditional theodolite, this paper presents a kind of evaluation model which uses the coefficients of the coefficient matrix of the solving equation as the evaluation model to evaluate the merits and demerits of the space rendezvous, and then introduces the particle swarm algorithm to solve the most The experimental results show that the evaluation model and the corresponding solution method are correct and effective. The uncertainty of the area coordinate measured by this method is the minimum, and this method is the layout problem of the transmitting station in the future The research has laid a useful foundation.
