Abstract:
With high-speed network and high-performance PC, networked telepresence, which allows a user to see a virtualized real scene in a remote place, has been investigated. Uyttendaele et al.[2004] have proposed a system which enables a user to change the viewpoint and view-direction interactively like walk-through in a real scene. However, the viewpoint is restricted onto the camera path. Kanade et al.[1997] have proposed a method which generates novel view images in the 3D dome. Their system needs the assumption that the positions of objects are limited within the area covered by the outside-in cameras. Therefore, it is suitable for 3D modeling, rather than telepresence. We propose a novel view telepresence system which enables a user to control the viewpoint and view-direction freely by virtualizing real dynamic environments. Our system uses multiple omni-directional cameras for virtualizing both inside-out and outside-in observations from camera positions in a real scene simultaneously. Furthermore, it can generate novel view images in real-time from omni-directional live videos transferred on network. The example is shown in Figure 1.
