基于Cesium的三维可视化场景建设及发布技术的研究

Research on 3D visualization scene construction and publishing technology based on Cesium

Cesium是当前最先进的开源三维GIS框架,无需安装任何插件,可直接在浏览器页面上展示三维虚拟地球并叠加丰富的地理要素,同时可以集成影像服务、地形服务、矢量服务和三维模型等。本文研究了基于Cesium的三维可视化场景建设及发布浏览技术。通过一系列技术手段可以将各种要素数据进行处理符合Cesium标准的格式,并进行发布和浏览。验证了通过Cesium技术搭建三维可视化场景并进行发布浏览的可行性。

Cesium is the most advanced open source 3 D GIS framework which can display 3 D virtual earth and overlay rich geographical elements directly on webpages without using any plug-ins.Moreover,it can integrate image service,terrain service,vector service,and 3 D model.The author team studied the construction and display of 3 D-visualized scene based on Cesium,and learned that element data can be processed by Cesium and released in corresponding format.Therefore,to build and release 3 D-visualized scene via Cesium is verified to be feasible.
