摘要: 通过分析直线摄影测量以及由此而扩展的广义点摄影测量的条件方程式,从理论和试验上证明了观测值之间的相关性和冗余度,讨论了用直线摄影测量进行空间后方交会的必要观测及观测值分布对精度的影响,为基于已有矢量航空影像自动外定向奠定了理论基础。

Abstract: This paper mainly focuses on analysis for the redundancy and relativity of the observation in line photogrammetry. The indispensable observations for space resection in line photogrammetry is discussed, so do the relationship between the precision and the position of observational points in line primitive. Finally two group experiments are carried out to prove the rationality of the proposed viewpoint.
