Virtu4D: a Real-time Virtualization of Reality
Résumé
In video surveillance systems, when dealing with dynamic complex scenes, processing the information coming from multiple cameras and fusing them into a comprehensible environment is a challenging task. This work addresses the issue of providing a global and reliable representation of the monitored environment aiming at enhancing the perception and minimizing the operator's effort. The proposed system Virtu4D is based on 3D computer vision and virtual reality techniques and takes benefit from both the "real" and the "virtual" worlds offering a unique perception of the scene. This paper presents a short overview of the framework along with the different components of the design space: Video Model Layout, Video Processing and Immersive Model Generation. The final interface gathers the 2D information in the 3D context but also offers a complete 3D representation of the dynamic environment allowing a free intuitive 3D navigation.
