一种用于室内虚拟环境的新表示

针对室内环境的虚拟问题，提出一种用于描述封闭环境的新表示.该表示由定义在经纬度平面上的光强-距离函数组成，可以支持3个自由度的全景浏览、连续变焦以及任意路线的移动.基于这种表示，给出一个使用少数照片创建室内环境的方法，它结合了基于几何和基于图象的绘制技术，算法快速稳定，对拍摄条件和硬件设备没有苛刻要求.

A New Representation for Indoor Virtual Environment

In this paper, the authors give a new representation for virtual reality, which is defined as an intensity-range function on a latitude-longitude plane. It supports three-degree-freedom viewing(yaw, pitch and roll), continuous zooming and walk-through in a virtual enclosed environment. On the basis of the representation, a hybrid approach is addressed for constructing virtual indoor environment, which only requires a sparse set of still photographs and has no strait restriction on taking original photographs. Experiment results show that the approach is robust.
