Three-dimensional Camera System for the Thin Three-dimensional Display Based on the Reconstruction of Parallax Rays

We have previously proposed the thin natural three-dimensional (3D) display system based on the reconstruction of parallax rays. In order to display real 3D scene, applying image-based rendering technique, we have also proposed a camera system that captures light ray data needed for reconstructing 3D images by using parallax rays reconstruction method from multiple images captured from multiple viewpoints. However, to reconstruct a 3D image of a real 3D object, many multiple images are required, because 3D images with an image depth of 25 cm can be displayed by the prototype thin 3D display. In order to reduce the number of required images, we used an interpolation algorithm suitable for the thin 3D display. This paper describes a 3D camera system for the thin 3D display, and also describes the experimental results.
