Abstract
3D TV requires multiple view images and it is very important to adjust parameters used for capturing and display of multiview images, which includes size of view images, focal length, and camera/viewpoint interval. However, the parameters usually vary from systems to systems and that causes a problem regarding interconnectivity between capturing and display devices. The Ray-Space method provides one of the solutions to such problems raised in 3D TV data capturing, transmission, storing, and display. In this paper, we first review the Ray-Space method and describe its relationship with 3D TV. Then, we introduce 3 types of Ray-Space acquisition systems: 100-camera system, space/time-division system, and portable multi-camera system. We also describe test data set provided for MPEG (Moving Picture Experts Group) Multiview Video Coding and 3D Video activities.
