Analysis for the Redundancy and Relativity of the Observation in Generalized Point Photogrammetry

摘要

This paper mainly focuses on analysis for the redundancy and relativity of the observation in generalized photogrammetry. After a short review of the constraint condition and observation equation in line photogrammetry and the derivative generalized point photogrammetry, the redundancy and relativity of the observation are analyzed based on derivative collinear equation in generalized point photogrammetry. The minimal observations for space resection is discussed, so do the relationship between the linear primitive and point one in the adjustment for space resection. Finally two experiments are carried out to validate the proposed viewpoint.
