摘要
智慧城市是数字城市的升级版,其管理服务的动态实现与虚拟地理环境联系紧密。本文首先综述了虚拟地理环境的概况;然后对虚拟地理环境运用在智慧城市中的关键技术作了归纳,分析了三维动态仿真、虚实交互、多智能体、数字孪生技术的特点及其在智慧城市管理中的适用范围;进而从应用的角度分析了虚拟地理环境在智慧城市中的研究现状与存在的挑战;最后总结出在人工智能和VR新时代下,虚拟地理环境在智慧城市中实时显示、高效算法、虚实交互等方面的发展前景。
Smart city is the updated version of digital city. The dynamic implementation of its management services is closely related to the virtual geographical environment. Firstly, the overview of virtual geographic environment is summarized. Then, the key technologies of the virtual geographic environment in smart city is concluded, and 3 D dynamic simulation, actual interaction, multi-agent, and the characters digital twin and scope of their application are analyzed. Then the research status and challenges of virtual geographical environment in smart city are analyzed from the perspective of application. Finally, the prospects in the new era of artificial intelligence and VR of the virtual geographic environment in the real-time display, efficient algorithm and actual interaction are concluded.
