基于图像的虚拟环境建模技术

综述了基于图像的虚拟现实环境的建模技术，并给出了各种模型表示的理论依据和建模过程的定义。把环境表示分为四类：全景图，光场数据库，深度图像和多投影中心图。全景图的生成包括基于图像相关性和基于图像整合变换的算法。光场数据库的分类主要依据全光函数。同时论述了在各种表示下的采样和建模技术。最后讨论了当前建模技术研究的热点及所需要解决的问题。

The Research of Image-based Modeling on Virtual Reality

We survey the techniques for image based modeling on VR(virtual reality). We present the theory basics of the representations and the definition of modeling procedure. We divide the virtual reality representations into four types: panoramic image, light field, depth image, multiple centers of project images. The generation of panoramic image includes correlation based techniques such as SSD and image registration techniques. The classification of light field mainly depends on plenoptic function. We discuss how to sample and model VR. At last, we discuss the major problems that will be overcome in the future
