Projective Compensation in Aerotriangulation
Publication: Journal of the Surveying and Mapping Division
Volume 104, Issue 1
Abstract
A 15-photograph block of simulated data is analyzed to evaluate the magnitude of projective compensation in aerotriangulation. Interior orientation errors in focal length and principal point coordinates as well as image errors due to image measurement (random), atmospheric refraction, lens distortion and film deformation are each simulated. When studied in the context of 6 μm random image error, the results indicate that interior orientation and systematic image errors are almost totally absorbed by changes in exterior orientation position and attitude. Previous investigations evaluating individual image error sources indicate a total image error larger than that reflected in the results of aerotriangulation tests. It is evident from this study that projective compensation, acting within the aerotriangulation adjustment process, is a significant factor contributing to this difference.
