摘　　要：在现有光电偏差标定方法的基础上,针对海上动态环境下多种方法测量及标定船载测量设备光电偏差结果一致性较差且难以选择的问题,提出了一种船载测量设备光电偏差计算及动态评估方法。该方法利用空间目标精轨信息能够反演计算高精度测元的特性,结合船载测量设备的测量数据建立测量方程计算光电偏差,以该计算结果为理论值对多种方法得到的光电偏差进行多属性优选,实测数据表明能有效解决动态测量情况下直接标定结果差异较大难以取舍的难题。Based on current photoelectricity deviation calibration methods, a new method on shipborne measuring equipments photo-electricity deviation calculation and dynamic valuation is put forward, aiming at solving the problem that is difficult to choose the optimum value among the inconsistent results of current various photoelectricity deviation calibration methods in the maritime com-plex dynamic environment.Taking the advantage of the precise character of theoretical elements ratiocinated from the information of precision orbits and combining the data from the shipborne measuring equipments, equations are set up to compute the photoelec-tricity deviation, which are just used as authentic true value to carry out multiattribute selection from those current various meth-ods.The results show that this method can overcome the problem to make choice of the reasonable one from those inconsitently di-rect calibration parameters.
