Real time 3D navigation in a static virtualized scene from a limited set of 2D data

Among the new data processing services and applications, virtual navigation in a real 3D world takes more and more importance and requires specific research. With regard to the reactions of the most important part of net surfers for example, we think that for a user of an interactive immersive tool, it is absolutely necessary to obtain a real time rendering of the virtual world, as natural and realistic as possible. That is why we focus our work on an image based approach, avoiding the slow and heavy handling of 3D models of the scene, generally not very realistic and typical in geometry based approaches. Our method uses for its part the synthesis of photorealistic views based on the trilinearity theory combined with image mosaicking. It especially minimizes the algebraic processings needed for view synthesis in order to offer in real time a natural rendering of the scene to the user, according to his/her relative movement from his/her initial position.
