Abstract
In this paper, we introduce a new 3D video display scheme that can present motion parallax for dynamic events recorded in a large-scale space such as a soccer stadium, concert hall, etc. We propose a simplified 3D object representation method with a single 3D plane and 2D texture. This enables the reduction of data size and the video rate generation of observer's view with small latency. Even though the detail of each 3D shape is lost, the positional relation among multiple objects can represent the motion parallax. The static background is supplied as ordinary 3D CG model and it is combined with the moving foreground objects. Another feature of our scheme is that it can receive stream data of 3D video from a server via Ethernet. The encoding framework of 3D video data stream and the rendering technique of observer's view are also described. The feasibility of the proposed scheme was demonstrated by a prototype system implemented by PCs.
