Paper Abstract

In projection-based virtual reality systems, such as the CAVE, users can observe immersive stereoscopic images. To date, most of the images, projected onto the screens, are synthesized form polygonal models, which represent the virtual world, This is because the resolution and the viewing angle of a real time are not enough for such large screen systems. In this paper, the authors propose a novel approach to avoid the problem by exploiting the human visual systems. In the proposed system, the resolution of the center of view is very high, while that of the rest is not so high. The authors constructed a four-camera system, in which the pairs of NTSC cameras are prepared for both left and right eyes. Four video streams are combined into one video stream and captured by a graphics computer. Wide-angle multi-resolution images are synthesized in real-time from the combined video stream. Thus, we can observe the wide- angle stereoscopic video, while the resolution of the center of view is high enough. Moreover, this paper proposed another configuration of the four-camera system. Experimental results show that we can observe three levels of viewing angle and resolution by the stereoscopic effects, while images for each eye has just two levels. The discontinuities in the multi-resolution images are effectively suppressed by this new lens configuration.
