Flight attitude imaging method and system of aircraft taking earth as target

The invention provides a method and a system for imaging the flight attitude of an aircraft taking the earth as a target, and the system comprises a central field-of-view lens group, a peripheral field-of-view prism group, a field-of-view fusion lens group and a detector. The field-of-view fusion lens group is used for imaging light entering from the central field-of-view lens group and light entering from the peripheral field-of-view prism group at different positions on the same image plane, and the detector is used for imaging light focused by the central field-of-view lens group, the peripheral field-of-view prism group and the field-of-view fusion lens group. And then analysis is carried out based on the imaged image so as to judge three attitudes of pitching, rolling and yawing of the aircraft, so that the complexity and power consumption of the lens are reduced, the weight of equipment is reduced, and the reliability of the equipment is improved. 本发明提供了一种以地球为目标的飞行器的飞行姿态的成像方法和系统，包括中心视场透镜组、周边视场棱镜组、视场融合镜组
