| Research Abstract |
In this project, we have developed a 3D video display system which works in a very large-scale space such as a soccer stadium, concert hall, etc. We 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. We describe a method 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.
We also have developed a live 3D video system that can capture video from multiple cameras, reconstruct 3D models and transmit 3D video data in real time. We represent a target object with a simplified 3D model consisting of a single plane and a 2D texture extracted from multiple cameras. This 3D model is simple enough to be transmitted via a network We have developed a prototype system that can capture multiple videos, reconstruct 3D models, transmit the models via a network, and display 3D video in real time. A 3D video of a typical soccer scene that includes a dozen players was processed at 26 frames per second.
