On-Line Point Positioning with Single Frame Camera Data

摘要

The project On-line point positioning with single frame camera data was concluded. The goal of the project was to develop a data processing concept for on-line high accuracy point positioning system. An operational on-line 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 simultaneous 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.
