Analysis for the Redundancy and Relativity of the Observation in Line Photogrammetry

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.
