3D VISUALIZATION THROUGH GEOVRML: A COMPROMISE BETWEEN MEASUREMENT AND REPRESENTATION

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, we’ll 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.
