Résumé

This paper aims to contribute in the research line dedicated to the development of tools that exploit 3D interactive visualization of geo-referenced spatial data in order to establish an Augmented Reality platform over we can integrate virtual 3D models with real environments support by GeoVRML. In this way, we have developed a program, sv3DVision, that enables to create, edit and complement 3D worlds, taking single oblique images and filler points (captured by surveying techniques) as input data. So, exploiting the geometry of oblique images support by vanishing points, weíll be able to pass from 2D to 3D, obtaining camera self-calibration, as well as virtual 3D models, which can be geo-referenced over a real environment generated automatically through Digital Elevation Models (DEM) with ortophoto. Finally, in order to complete the 3D scene, sv3DVision allows adding independents geo-referenced elements as: simple geometries (urban furniture), backgrounds and different visual effects. Therefore, through sv3DVision and GeoVRML, weíll achieve object uniqueness exploiting representation and analysis capabilities, as well as the integration under the same environment of metric rigor and visual quality
