摘    要:虚拟现实的一个重要目标是使用计算机生成逼真的视觉世界,使用户可以对虚拟世界的客体进行交互式考察.虚拟现实的实现有两种方法.传统上,用三维图形学的方法实行建模和绘制.此方法需要繁琐的建模和昂贵的专用绘制硬件,而且图形绘制的质量和场景的复杂性受到很大的限制.基于图象的绘制是实现虚拟现实系统的一种新方法.它克服了三维图形方法的缺点.本文在总结已有技术的基础上,提出一个实现基于图象绘制的虚拟现实系统模型,并据此模型实现一个实验系统及相应的图象工具.

关 键 词:虚拟现实    图象绘制    全景图    图象拼接

Abstract:The most important goal of the virtual reality is to create a virtual world by computers to allow users control the virtual objects interactively. Traditionally, the virtual reality systems use 3D computer graphics to model and render a virtual environment in real time. However, this approach usually requires laborious modeling and expensive special purpose rendering hardware. The rendering quality and scene complexity are often restricted due to the real-time constraint. Image-based rendering is a new approach in composing a virtual environment in which a set of panoramic images are used to compose the virtual environment and walk in the space is accomplished by "hopping" to different panoramic points. This paper provides a model for creating an image-based virtual reality system. By using this model, an experience system referred to as QUICK SHOW is accomplished with some additional image tools implemented.
Keywords:Virtual reality  image-based rendering  panoramic image  stitching
