Based on weighted factor of the photoelectric theodolite track measurement

针对光电经纬仪测量误差因素,提出加权因子的异面交会方法。首先建立光电经纬仪异面交会测量模拟,对异面误差问题采用加权因子控制设计,引入测量误差的人为因素作为模型参数隐含在模型中,运用最优化方法求解上述约束方程,解得经纬仪的模型参数,从而从原理上消除人为因素带来的误差,提高测量模型的精度,最后建立空间目标模型并进行仿真计算,得到了航迹测量优化后的坐标。仿真结果表明误差小于交会误差,测得数据较真实的反应飞行航迹,提高对被测目标的定位精度。

Theodolite measurement error factors,presents a weighted factor in nonplanar intersection method.First of all,will personally set up different measurement theodolite simulation,then the existence of different surface error control design problem using the weighted factors,introduction of the human factor as a measurement error model parameters implicit in the model,using optimization method for solving the constraint equations,solve for theodolite model parameters,thus theoretically eliminating the error caused by human factors,to improve the measurement accuracy of the model,and finally to establish a spatial object model and simulated,are the coordinates of the optimized trajectory measurement,The simulation result indicated the error is smaller than the junction to meet the error,obtains the data real response flight track,enhances to is measured the goal the pointing accuracy.
