PHOTOGRAMMETRIC MATHEMATICAL TARGETING RESEARCH.
Abstract
The results of an investigation of numerical and electronic computer techniques for solving the large system of normal equations arising from analytical photogrammetric mujtiple-station aerotriangulation are presented. Four different internal arrangements of the normal equations; three point-iterative and two block-iterative procedures for solving the normal equation system; and compacting of the normal equations are discussed, and results of tests of the various possible combinations of equation arrangements and iterative techniques are presented. Results reveal a particularly attractive solution technique which provides an efficient, economical, and accurate means of performing this type of adjustment; and results in a nearly linear proportional increase in the computer time required as the number of photographs is increased.
