摘　　要：真实纹理是风景区三维虚拟旅游系统具有真实感的关键之一,但在使用真实纹理构建风景区三维虚拟旅游系统中还存在着一些问题,真实纹理库的建设将有效地改善这些问题。本文在分析虚拟旅游系统对真实纹理库的需求的基础上,提出了能够存储和管理多源、多时相、多分辨率、能够无缝覆盖整个风景区所有景观表面的纹理元的风景区三维虚拟旅游系统真实纹理库的建设构想。Real-texture is one of the most important parts for the real-feeling of a 3D virtual tourism system, but there are many problems when using the real-texture, the real-texture database can resolve these problems in certain degree. In this paper, the author analyses the requirements of the virtual tourism system on the real-texture database firstly, then puts forward to the ideas of constructing a real-texture database which contains many multi-source, multi-resolution and multi-time real-texture units, these real-texture units could cover the surface of all the landscapes.
