光电载荷安装误差标校的飞行航路

无人机搭载光电载荷进行安装误差标校时,飞行航路的选择与规划在很大程度上影响着标校算法的收敛性与误差识别结果。为增强标校飞行架次的有效性,提高安装误差可被识别的程度,改善标校算法的收敛性及标校精度,对标校的原理和标校算法进行了理论分析,并利用考察差异函数偏微分的方法找到了标校航路和安装误差标校之间的相互联系,然后结合标校实施过程中所遇到的实际问题提出标校航路规划应遵循的原则,给出了标校航路规划的参考范例。

Flight route planning by installation error calibration of photoelectric payload

The flight route planning by installation error calibration of photoelectric payload has a great effect on the convergence of calibration algorithm and the final result of identification.In order to increase the level of installation error identification and improve the convergence and accuracy of calibration algorithm,this paper made a theoretic and analysis of the principle and algorithm of calibration,and determined the interrelationship of flight route and calibration by investigating partial differential of divergence function.According to the principles obtained from the practical problems in the process of calibration,a reference example was presented for the flight route planning.
