以未来社区建设需求为导向，研究探索实景三维在未来社区中的应用。采用Cesium三维地理信息引擎开发未来社区实景三维地图系统。系统采用4层框架体系前后端分离技术。针对系统加载大量二三维多源异构数据缓慢的问题，重点研究了实景三维地图系统的性能优化方法，分别从实景三维场景初始化、实景三维动态单体化查询以及专题和物联网数据展示3个方面进行改进，有效提升了系统的初始化速度和渲染效率。该系统已广泛应用于宁波市镇海区未来社区数字化建设中。

Guided by the needs of future community construction, we explored the applications of 3D real sense in future communities. We used Cesium 3D geographical information engine to develop a 3D real sense map system for future communities, which adopted four layers framework system with front-end and back-end separation technology. In response to the problem of slow loading of a large amount of multi-source heterogeneous data in 2D and 3D, we studied the performance optimization methods of 3D real sense map system, and improved the system from the initialization of 3D real sense, dynamic monolithic query of 3D real sense, and display of thematic and IoT data three aspects, which could effectively improve the initialization speed and rendering efficiency of this system. The system has been widely used in the digital construction of future communities in Zhenhai District, Ningbo City.
