摘　　要：在旅游信息网站中,利用虚拟现实技术进行景点展示取得的效果比使用文字和图片更生动。目前利用虚拟现实技术进行场景展示的3种主要方式为单机仿真软件、Web3D和全景图。该文提出一种利用Google Earth技术进行在线场景展示的方法,综合上述方式的优点,实现对大场景的加载、Internet对接以及与全景图的组合。该方法利用Servlet返回动态KML,激发Google Earth启动并显示场景。利用KML控制地标显示、地标说明图文和3D模型加载。通过说明图文中的超链接,让地标链接到全景图网页或Servlet,以返回3D模型数据。In tourism information site, using virtual reality technology to display attractions is more lively and interesting than using words and pictures. There paper three major ways when using virtual reality technology to display scenes： simulation software in single computer, Web3D and panorama. This article brings a method that using Google Earth to display the scene online. It combines the advantages, abandon shortcomings which are in the three aforementioned ways. It can load large scene while connecting lnternet, and cooperate with panorama. The method use Servlet to return dynamic KML, which let Google Earth start and display scenes. KML can be use to control the display of place mark, graphic notes and loading of 3D models. Place mark can be linked to panorama Web page or Servlet which will return 3D model via hyperlinks in the place mark notes.
