摘　　要：分析了虚拟现实技术的原理、方法及目前研究的领域和现状,探索了如何运用虚拟现实技术进行虚拟环境的构造和漫游系统的设计.设计了一个虚拟环境及在虚拟环境基础上完成的漫游系统.该软件系统分为4个子系统,即输入子系统、全景图生成子系统、漫游子系统和输出子系统.应用结果表明,该系统能对基于图像的虚拟现实环境进行构造并实现快速漫游.This paper analyses the principle and method of virtual reality and the present state of research in the fields, and ways to use the technology of virtual reality to design and implement the system of the construction and ramble of virtual environment. The aim of the system is to develop a virtual environment and achieve ramble on the basis of virtual environment. This software system is composed of four subsystems which include input subsystem, generatepanorama subsystem, rambling subsystem and output subsystem. And this system adopts environment modeling method, panorama generating technology and so on. The result indicates that this system can construct virtual reality environment based on picture and realize fast ramble. 
