摘　　要：国内Cesium地图引擎研究处于起步阶段,针对当前基于Cesium智慧社区开发贫乏问题,本文基于Cesium和WebGL技术进行开发试探,建立了基于倾斜摄影模型的三维智慧社区系统。通过导出Cesium 3D Tiles、搭建开发平台和相关类库函数调用,实现了三维智慧社区可视化控制、空间测量、可视性分析和空间查询功能。实验结果表明,Cesium和WebGL类库函数功能强大,开发方法简单,构建的三维智慧社区系统兼容性、开放性与可移植性强,支持倾斜三维模型海量数据加载与并发访问,有效降低系统建设成本,不失为一种轻量级智慧社区Web开发方法。The research of Cesium map engine in China is still in its infancy,for the lack of development of Cesium-based intelligent community,this paper explored the development of Cesium-based and WebGL-based technologies,and established a three-dimensional intelligent community system based on oblique photography model.By exporting Cesium 3D Tiles,building development platform and calling related class library functions,the functions of three-dimensional intelligent community visualization control,spatial measurement,visibility analysis and spatial query are realized.The experimental results showed that Cesium and WebGL class libraries have powerful functions,simple development methods,strong compatibility,openness and portability of the constructed three-dimensional intelligent community system,and it supports massive bolique three-dimensional model data loading and concurrent access,effectively reduce the cost of system construction,and could be regarded as a lightweight intelligent community Web development Method.
