我们开发了一种利用视差重建方法的实时彩色自动立体显示系统。值得注意的是能够显示体积图像，如全息照相。此外，该系统的数据量比全息图的数据减少了很多。此外，该系统不需要特殊的眼镜就可以被多个观众同时看到。众所周知的积分摄影(IP)类似于我们的系统。IP伪镜图像是目前必须解决的最重要的问题。在我们的显示器上使用光线空间表示的方法，不可能出现伪视像。本文描述了一种基于光线空间表示的三维图像输入系统，该系统采用视差重建的方法实现彩色三维显示。光线空间表示是一种基于图像的绘制技术。它使用真实物体的图像来重建复杂形状物体的照片真实感图像，而不需要任何显式的几何模型。利用光线空间表示中的参考平面与该3D显示器屏幕之间的相似性，我们可以在任意观察点观察到3D图像的视差射线由大量的视差图像组成。作为实验结果，对折纸鸟(鹤)的三维图像进行了重建。
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.
