摘　　要：针对传统光电吊舱安装误差地面标定需要借助专用仪器,反复调整以致操作繁琐的问题,提出了一种空中标定方法。在载机飞行过程中,通过选取视场内已知坐标的合作目标进行跟踪,利用载机位置、载机姿态、光电吊舱的观测指向角度、合作目标的位置等数据,对光电吊舱的安装误差角进行实时拟合解算处理,保证标定精度的同时,可极大节省工作量,提高效率。Aiming at the issue of complex operation caused by the need of specialized instruments for ground calibration of installation errors in traditional optoelectronic pods,which requires repeated adjustments,an airborne calibration method is proposed.In the process of carrier flight,by selecting the cooperative target with known coordinates in the field of view for tracking,and using the data such as carrier position,carrier attitude,observation pointing angle of the photoelectric pod,and the position of the cooperative target,the real-time fitting solution of the installation error angle of the photoelectric pod can be carried out.This proposed method can greatly save the workload and improve the efficiency while ensuring the calibration accuracy.
