基于数字地球平台的三维虚拟数字校园建设

Establishment of 3D Virtual Digital Campus Based on the Digital Earth Platform

以虚拟成都理工大学为例,论述了一种高效、低成本的网络虚拟校园建设方法,即利用数字地球平台的基础地理框架和遥感底图,使用建模工具进行三维建筑群模型建立,经过投影和坐标变换处理,实现网络虚拟校园的建设与实施。实验证明,数字地球平台凭借其在丰富资源、网络传输、三维显示等方面的优势,是包括虚拟校园在内的数字工程建设的有效工具。

Taking Virtual Chengdu University of Technology as an example, This paper discussed an efficient, low-cost method of building virtual campus network, the specific use of digital earth platform on the basis of remote sensing and geographical framework maps, the use of 3D modeling tools for building a model group, after processing projection and coordinate transformation, Network virtual campus construction and implementation. Experiments prove, Digital Earth platform is an effective tools for project construction including the virtual campus, by virtue of its abundant natural resources, network transmission, three-dimensional display of the advantages.
