【摘要】：POS系统是移动测量系统的重要组成部分。由于系统集成影响,POS系统中心的运动状态无法直接观测。因此,可采取设置相关测量合作目标的方法,在确定其与POS系统中心的位置基础上,通过观测合作目标来确定POS系统中心的运动状态。从车载移动测量系统空间基准统一方程出发,提出了一种解算测量合作目标安置参数的方法,并以此为基础,系统分析POS系统定位定姿误差、全站仪测距测角误差、尺度因子误差等误差源对安置参数解算的影响,推导了安置参数解算的误差模型。实验结果表明,采用本文解算方法,可以获取毫米级的合作目标安置参数,满足合作目标应用于动态测量检测POS系统定位精度的需求。
[Abstract]:POS system is an important part of mobile measurement system. The motion state of POS system center can not be observed directly because of the influence of system integration. Therefore, we can adopt the method of setting the cooperative target of correlation measurement, on the basis of determining its position with the center of the POS system, we can determine the moving state of the center of the POS system by observing the cooperative target. Based on the unified equation of spatial datum of vehicular mobile measurement system, a method of solving and measuring the parameters of cooperative target placement is put forward. Based on this method, the positioning and attitude error of POS system and the range angle error of total station are analyzed systematically. The effect of error sources such as scale factor error on the settlement of placement parameters is discussed. The error model of settlement parameters is derived. The experimental results show that the cooperative target placement parameters of millimeter scale can be obtained by using the solution method in this paper, which meets the requirement of the location accuracy of the cooperative target applied to the dynamic measurement and detection of POS system.
