On-line point positioning with single frame camera data

The project "On-line point positioning with single frame camera data" was concluded on December 31, in 1991 after aperiod of three years. This final report presents the investigations and results of this project. The goal of the project was to develop a data processing concept for on-line high accuracy point positioning system. An operational on-Iine system, installed in a UNIX environment under the programming language "C", for aerial phototriangulation working on an analytical plotter or on a digital workstation should provide high speed of operation, accuracy of results, and ease of data management. Established tests showed that the Sun Microsystems workstations have sufficient memory capacity and speed performance to run on-line triangulation applications. The adopted algorithms in the on-line triangulation system for the computation of initial values, for the sequential and simultanous adjustment and for quality control will be presented in this report. A description of the developed software modules and the program will also be given. Although this system was designed and developed specifically for aerial triangulation, it is anticipated that future applications for on-line triangulation algorithms and methods will be found in robotics and industrial quality control.
