【摘要】 在虚拟现实技术中 ,立体视觉系统虽然应用较为广泛 ,但观察工具配戴起来不够方便舒适 ,而且容易使眼睛疲劳 ,所以裸眼可视立体技术一直是研究的热点 .本文分两类介绍了近年来国外裸眼可视立体技术的发展概况 ,一类是平面图像立体化技术 ,另一类是利用光学作用使得平面图像中不同的图像进入两眼 ,再根据人的两眼的生理融合作用 ,使得对平面图像有立体感 .最后对各种技术进行比较 ,提出了裸眼可视发展的方向更多还原

【Abstract】 In VR (Virtual Reality ) technology, the application of stereoscopic display system calls for wearing special observing devices such as HMD and stereoscopic glasses. These devices are inconvenient and uncomfortable, and eyes are prone to get tired. So, autostereoscopic display technology is the hot topic of research nowadays. In this paper, we introduce the overseas development of two kinds of autostereoscopic display technology. One kind is stereovisionizing the flat image. The other, utilizing the optical process, makes different images from the original flat image enter into two eyes, and, by syncretic function of the eyes, makes the flat image look stereoscopic. Finally, by comparing these technologies, the authors suggest the future development of the autostereoscopic display technology.更多还原
