数字孪生下的超大城市空间三维信息的建设与更新技术研究

Research on the Construction and Updating Technology of Three-Dimensional Spatial Information of Megacities under Digital Twi n

当前,以物联网、大数据、人工智能、5G传输等新技术为核心的数字浪潮正在席卷全球,数字世界为了服务物理世界而存在,物理世界因为数字世界变得高效有序,数字孪生技术应运而生,影响着城市空间规划布局、建设与发展。城市高时间分辨率的三维空间信息是数字孪生城市建设的基础,该文围绕城市空间三维地理信息建设与地理信息的现势性,结合测绘遥感前沿技术、物联网通信传输以及协同管理机制,全面思考了三维地理信息建设以及更新的技术手段,对城市信息化建设具有一定的参考应用价值。

At present,the digital wave centered on new technologies such as Internet of Things,big data,artif icial intelligence,and 5G transmission is sweeping the world.The digital world exists to ser ve the physical world.The physical world has become eff icient and orderly,for the application of digital technology.Born,it affects the city planning,construction and development of urban space.The high-time resolution of urban three-dimensional spatial information is the basis of digital twinning city construction.This paper focuses on the three-dimensional geographic information construction of urban space and the currency of geographic information.Combined with the cutting-edge remote sensing technology,Internet of Things communication transmission and col laborative management mechanism,we research the constr uction and updated technical means of the three-dimensional geographic information,having certain reference application value for urban information construction.
