A Perceptually Correct 3D Model for Live 3D TV

3D modeling of a scene is essential for the generation of 3D video from multiple images. In this paper, we present a perceptually correct 3D modeling scheme. "Perceptually correct" means that it may not represent the physically correct object shape but it can generate perceptually almost-correct views of the object. A perceptually correct 3D model is an approximation of the physically correct 3D model, but it can be constructed more easily and stably from images. The quality of 3D video generated using a perceptually correct 3D model could be better than that generated using a physically correct model, when the models are constructed from images. A live 3D TV system for soccer scene has been developed based on the modeling scheme.
