【摘要】：为了实现室内空间测量定位系统(w MPS)发射站定向参数的快速、精确校准,提高其方法的适应性,研究了一种新的发射站定向方法.本方法借鉴工程测量中的后方交会原理,在w MPS发射站数学模型基础上,引入坐标控制场建立冗余光平面约束,得出参数优化函数.通过拉格朗日乘子法求取定向参数初值,进行优化解算.本方法可以实现发射站的自动定向.搭建了实验平台并以激光跟踪仪测量结果作为比对基准,验证了校准方法的准确性.由本方法完成定向的w MPS测量点位误差优于±0.3 mm,且满足大尺寸坐标测量的精度要求.
[Abstract]:In order to realize the fast and accurate calibration of the orientation parameters of the (w MPS) transmitting station in the indoor space measurement and positioning system and to improve the adaptability of the method, a new method for the orientation of the transmitting station is studied. Based on the mathematical model of w MPS transmitter station, the coordinate control field is introduced to establish redundant optical plane constraints, and the parameter optimization function is obtained by referring to the principle of rear intersection in engineering survey. The initial value of directional parameters is obtained by Lagrange multiplier method, and the optimization solution is carried out. The method can realize the automatic orientation of the transmitting station. The accuracy of the calibration method is verified by setting up the experimental platform and using the measurement results of laser tracker as the reference. The position error of w MPS measured by this method is better than 卤0. 3 mm, and meets the precision requirement of large size coordinate measurement.
