【摘要】 本文主要介绍了解决三线阵CCD影像短航线空中三角测量问题的自由外方位元素平差方法及相关数学模型,按不同的卫星摄影测量条件,分别用直接前方交会、自由外方位元素平差方法及外方位元素观测值参与平差,进行了数学模拟计算,结论是:采用自由外方位元素平差方法,可以构建精度与直接前方交会相当,但“无y视差”的短航线立体模型。更多还原

【Abstract】 In this paper,in order to resolve the short strip aerial triangulation,a free exterior orientation element adjustment method and it’s mathematical model are introduced.According to different conditions in satellite photogrammetry,the simulated calculations are made,using forward intersection and free exterior orientation element adjustment as well adjustment with observations of exterior orientation.Free exterior orientation element adjustment method can be used to construct the short strip stereo model with an accuracy similar to forward intersection but "no yparallax".更多还原
