基于Google Earth的哈尔滨师范大学三维模型的建立
Establishment of 3-Dimensional Model of Harbin Normal University Based on Google Earth

随着计算机的逐步发展，虚拟现实技术和网络技术的结合使用可以产生较二维模型更加直观形象的三维立体模型。本文在分析Google Earth平台的基本特征、技术支持以及优势对比的基础上，结合SketchUp建模平台，实现了哈尔滨师范大学校园的三维建模，阐述了建筑物以及树木、道路等对象的建模方法，并解释三维模型发布到Google Earth的条件。通过实际案例研究其应用效果，为实现虚拟校园系统设计以及简单的可视化和交互、校园的数字化打下基础，为景观规划设计方案的可视化呈现提供参考。
With the development of computers, virtual reality technology and network technology can produce a more intuitive image of the three-dimensional virtual campus technology. Based on the analysis of the basic features, technical support and comparative advantages of Google Earth platform, combined with SketchUp modeling platform, this paper realizes the three-dimensional modeling of Harbin Normal University campus, expounds the modeling methods of buildings, trees, roads and other objects, and explains the conditions for publishing the three-dimensional model to Google Earth. Through the actual case study and its application effect, it lays the foundation for the virtual campus system design, simple visualization and interaction, and the digitalization of the campus, and provides a reference for the visual presentation of landscape planning and design schemes.
