Three-Dimensional Circular Camera System for the Three-Dimensional Display Based on the Reconstruction of Parallax Rays

We have previously proposed the three-dimensional (3D) display system based on the reconstruction of parallax rays. In order to display real 3D object, applying image-based rendering technique, we have also proposed a camera system that captures light ray data needed for reconstructing natural 3D images by using parallax rays reconstruction method from multiple images captured from multiple viewpoints. However, because the previous camera system was straight arrangement, the ray information of the object could be acquired only from one side. In order to reconstruct a 3D image of a real object which can be observed from surrounding multiple viewing points, multiple images which captured from multiple viewing points around a real object are required. Thus, we propose a circular camera system that captures light ray data of a real object from circular multiple viewpoints. To reduce the number of component cameras of the circular camera system, we also propose an interpolation algorithm. This paper describes an interpolation algorithm of the circular camera system.
