摘要
在立体视觉系统中,一般采用空间分离且同步旋转的两台摄像机拍摄同一物体,为观察者提供同一物体的两个不同角度的图像。文章从人类的视觉感知原理出发,给出了基于单幅图像的体视图像生成算法,并成功地用于大数据量体视转换的场合,如“国家大剧院”和“奥运会场景”的漫游仿真,从而实现虚拟复杂场景的仿真漫游。该算法特别适合于要求快速、一次绘制(拍摄)的场景,即再现立体的场合。
In stereoscopic system, the common method to provide user with stereoscopic image pair is shooting the objects with two cameras, which is in different location in space but rolls and rotates synchronously. In this paper, the stereoscopic image generation algorithm based on the stereo vision and digital image transformation is given. At same time, video processing application examples, such as the simulation of “National Great Theater” and “Facilities of 2008 Olympic Games”, are presented. The simulated roam in the complex virtual scene can be implemented via the system using this algorithm. This algorithm can find application in the case, which requires getting stereo vision quickly from a one- time rending.
