Abstract
The procedure of simultaneous adjustment of photographs has been developed utilizing a method of least squares at the object points. An attempt has been made to develop a new set of condition equations defining the relation between each object point and its corresponding rays from exposure station positions. The mathematical formulations based on the set of condition equations have led to a feasible computational procedure. In particular the structure of the coefficient matrix of normal equations has been examined carefully, in order to conserve the limited computer storage capacity and also for the purpose of saving execution time in the computer. Reduction of the coefficient matrix of the normal equation system to a favorable bandwise structure has been performed by changing the order of obseevation equations which are used form the normal equations.
The procedure has been coded in FORTRAN IV and computed on an IBM 360/50 computer at the Comuter Center in the University of New South Wales.
The procedure has been tested using simulated data of near vertical photography, prepared by the Autometric Corporation of the Raytheon Company, for the U.S. Army Engineering Topographic Laboratories. Fictitious blocks of five strips of five photographs and three strips of ten true coordinates of the image points and the object points.
This projecc was accomplished as the thesis of Master of Surveying in the University of New South Wales, Australia.
