虚拟现实场景中立体视差生成算法的研究

近几年来，虚拟现实技术的广泛应用前景引起了国内外越来越多学者的兴趣和重视，而且国外的一些机构在这方面的研究也已经取得了一些很重要的成果。立体显示技术是虚拟现实的关键技术之一，而对视差的研究又是立体显示技术一个很重要的方面。该文首先论述了双眼的生理结构和双眼视差的形成以及计算机上实现立体视觉的原理，然后对虚拟现实中生成双眼视差得到立体图对的多种方法进行了研究，并在虚拟现实设备上实现，通过比较和分析各种显示效果给出了研究结论。

Study on the Generation of Parallax for Virtual Environments

In recent years, more and more scientists began to have interest in the wide-scale application prospect of Virtual Reality technology and pay attention to it, and some research establishments of western countries have already achieved some important results. Stereoscopic displaying is one of the key technologies for virtual reality, and the research on parallax is very important for stereoscopic display technology. In this article, the following aspects are discussed: Firstly, physiological structure of human eyes and optical parallax are introduced, and the principal of realizing stereoscopic vision on computers is talked about; Secondly, several popular methods for generating stereoscopic image pair are researched and applied to a virtual environment example; Finally, with the help of virtual reality equipments, after comparing and analyzing the displaying result, some important conclusions are drawn.
