Method on Realizing Stereoscopic 3D Display based on Nvidia Display Drive//Hu Yuehui, Hu Qiuhua
Abstract The stereo display is one of the developing directions for the future information display system. In this study, Method to implement stereo display based the popular used Nvidia display driver in PC was proposed, after the stereo display was introduced briefly. The tests were carried out by the stereo glass and the custom-developed stereo monitor, and the results showed that in order to improve and develop the multimedia equipments and teaching quality by stereoscopic 3D display, using the Nvidia display card was one of the best ways, which was very easy and inexpensive.

1 引言
在當今多媒體時代,立體顯示技術正在逐步成為是一項不可缺少的技術,因為它不僅可以再現生動的立體景象,而且還可以精確地描繪物體的遠近、縱深和圖像的現實分布狀況,從而使觀察者獲得更加全面的信息。立體顯示技術除了應用于廣告和娛樂產品,在教育、醫學、軍事等領域也有廣泛的應用前景。
目前立體顯示設備已經開發出包括立體眼鏡、立體顯示器、立體投影設備等在內的多種產品。其中常見的是雙目視差(Binocular Parallax)原理的立體成像技術[1,2],即利用人的雙眼從不同的方位獲取同一景物的信息,各自得到關于景物的二維圖像,在視網膜上所形成的光學像略有差異,人的大腦通過對左右兩幅圖像以及兩幅圖像的視差進行分析和處理后,可以得到關于景物的光亮度、形狀、色彩、空間分布等信息,將視場(即眼睛所觀看到的景物區域)中的物體區別出遠近,感受到所看到物體的立體層次而產生立體感?!?br>
