free azimuth

Using the three-line-array CCD imagery simulated from the APOLLO imagery and the simulated orbit and attitude parameters of the Chang’ e-1 satellite, according the method of equivalent frame photo(EFP) and free elements of exterior orientation(FEO), the elements of exterior orientation and the coordinates of model points are calculated in photogrammetric coordinate system.

本文采用APOLLO影像模拟生成的嫦娥一号三线阵CCD影像及其卫星的轨道与姿态模拟参数,按等效框幅像片(EFP)法和自由外方位元素(FEO)法分别计算摄影测量坐标系内的外方位元素及模型点坐标,生成了数字高程模型(DEM)、等高线、正射影像及三维地形仿真影像,评估了从模拟月球三线阵CCD影像生成的摄影测量成果的预期精度。
