Abstract

We have developed a real-time color autostereoscopic display system using a reconstruction method of parallax rays. The notable point is to be able to display a volumetric image such as holography. Moreover, the data of this system can reduce much than that of hologram. Also, this system is visible to multiple viewers at the same time without special glasses. Well-known integral photography (IP) is similar to our system. Pseudoscopic images for IP are the most important problem that has to be solved. Using the method of ray-space representation on our display, it is not probability to appear pseudoscopic image. This paper describes the three-dimensional (3D) image input system based on ray-space representation for a color 3D display using a method of the reconstruction of parallax rays. The ray-space representation is one of image-based rendering techniques. It uses images of real objects to recreate photo realistic images of complex shaped objects without any explicit geometric model. Using similarities between a reference plane in ray-space representation and the screen of this 3D display, parallax rays for a 3D image, which we can observe at arbitrary viewing point, compose of amount of some parallax images. As an experimental result, the 3D image of origami bird (crane) is reconstructed.
