Scalable 3D representation for 3D video display in a large-scale space

The authors introduce their research for realizing a 3D video display system in a very large-scale space such as a soccer stadium, concert hall, etc. They propose a method for describing the shape of a 3D object with a set of planes in order to synthesize a novel view of the object effectively. The most effective layout of the planes can be determined based on the relative locations of an observer's viewing position, multiple cameras, and 3D objects. A method is described for controlling the LOD of the 3D representation by adjusting the orientation, interval, and resolution of planes. The data size of the 3D model and the processing time can be reduced drastically. The effectiveness of the proposed method is demonstrated by experimental results.
