Estimating approximate values before bundle adjustment in close-range photogrammetry: a review

The paper gives a review of applied and potential algorithms for estimating approximate values before the bundle adjustment of close-range data: This estimation is mainly considered a problem of solving polynomial equations. Some general approaches to the polynomial solution problem as treated in numerical mathematics are given. There is also a discussion of particular photogrammetric estimation methods and their polynomial formulation. The discussion provides a basis for making decision on method of estimating approximate values in the various situations met in close-range photogrammetry.
