基于光线跟踪的虚拟场景立体图像对视差研究

摘要

Disparity of stereo image pairs forms the basis of stereoscopic display, and the basic principle of binocular stel~eoscopic display is that the left and right images in stereo pairs with disparity are sent to the left eye and right eye respectively, resulting in a stereo sense. This paper presents a method to compute the disparity of stereo pairs in a vil~ual scene using ray tracing, by which disparity maps and depth maps are created. Besides, the characteristics of and factors affecting the disparity are analyzed.%立体图像对的视差是立体显示的基础，双目立体显示的基本原理就是将具有视差的立体图像对中的左右眼圈像分别送入左右眼中，从而产生立体感．本文给出了一种在虚拟场景中利用光线跟踪计算立体图像对视差的方：去，生成了视差图和深度图，并对视差的特点和影响视差的因素进行了分析．
