摘要: 虚拟现实是一项涉及计算机图形学、人机交互技术、传感技术、人工智能等领域的综合集成技术。它用计算机生成逼真的三维视、听、嗅觉等感觉,使人作为参与者通过适当装置,自然地对虚拟世界进行体验和交互,最终使得参与者产生身临其境之感。在分析虚拟现实定义及软硬件构成的基础上,提出了虚拟地理环境的概念及其技术实施路线,探讨了虚拟现实技术在地理学中的应用前景。

Abstract: The Virtual Reality is a composite technique. It can create the lifelike feeling such as visual, hearing and smell sense, make people participate the virtual world, and give people the sense of being personally on the scene. The Virtual Reality System is composed of the hardware such as the graphic workstation, the display equipment and the sensor instruments; it is composite with 3D modeling, virtual scene driving and sensor controlling software, etc. 3D modeling, interacting, sensing and computing technique supports the Virtual Realty. The Virtual Geographical Environment (VGE) comes out of the using of the Virtual Reality in Geography. VGE makes it realized that the geographer could design and modify the geographical correlation, analytic and engineer model according to the personal technology, supposition and plan, and observe the result through interacting with it. With the developing of application of the Virtual Reality in Geography, the science of Geography will be explored more deeply. In geographical education, because the Virtual Reality expresses the technology and concept in lifelike feeling, the educated person will be more interested in it, and it may lead to better results. In theory study, the Virtual Reality may realize the virtually reappearing of the most part of geographical studying activity, which can help the geographer immerse in certain 3D scene wholly, so that they can give full play to their geographical ability of thinking and imagination. The virtual geographical experiments can be done by the Virtual Reality, which makes geographical simulation repeatable. Furthermore, the Virtual Reality is important in the practice of urban planing, tourism, and disaster prevention, and so on.
