Vision field capture for advanced 3DTV applications

The seven-dimensional plenoptic function provides a full description of the visual information for the real world. In this paper, we present a novel concept called vision field, which simplifies the seven-dimensional plenoptic function into its three subspaces, namely, view, light, time. Based on this concept, we found that most previous 3D capture systems can be related to the vision field capture. This paper first gives a brief survey on the previous 3D capture systems, categorizes them from the vision field perspective. Then, we introduce a system which is able to capture the vision field. A Multi-View-Multi-Lighting (MVML) capture system is built to obtain the multiview images of the 3D scenes or objects under different steerable light conditions. Finally, we show how the vision field capture can be used for advanced 3DTV applications.
