Integrating photogrammetry into raster and vector information systems for setting databases for engineering projects

Abstract

The correlation methods presented here use 3D image processing techniques to set up virtual stereo models and integrate them in spatial digital information systems. The coordinates of any selected point are made available more accurately than by methods of photogrammetric restitution, and the user requires no training in stereoscopy. The metrical and documentary information generated here, in comparison with what is current, is better suited for the development of geo-spatial engineering projects. It is also of a quality to improve the execution of projects using automatic machinery. The developed techniques enable the project designer to build his data base interactively as part of the geometric design process.
