摘　　要：针对光电经纬仪测量的异面定位误差,采用加权因子算法进行调整;首先建立空中测量目标的定位模型,为避免因各种误差对测量数据的影响,接着用加权因子对目标无偏估计,通过调整加权因子提高测量模型的精度,最后建立模型并进行仿真实验,得到了精确的航迹坐标,仿真结果表明减少虚假航迹,提高对被测目标的定位精度。In view of the photoelectricity transit survey different surface position error,uses the weighting factor algorithm to carry on the adjustment.First establishes the aerial survey goal the localization model,because for avoids each kind of error to surveying the data the influence,then uses the weighting factor to the goal unbiassed estimate,through the adjustment weighting factor enhancement survey model precision,finally establishes the model and carries on the simulation computation,obtained the precise flight path coordinates,the simulation result had indicated the reduced untrue flight path,enhanced to is measured the goal the pointing accuracy.
