面向数字孪生城市的智能化全息测绘

Intelligent perfect-information surveying and mapping for digital twin cities

以大数据、物联网、人工智能、虚拟现实、云计算、智能驾驶等新技术为代表的信息化浪潮席卷全球,数字世界与物理世界正形成两大平行发展、相互作用的体系,数字孪生技术应运而生。随着物联网技术(IOT)的发展,数字孪生的理念被引入到智慧城市建设中来,深刻影响着城市规划、建设与治理。笔者所在单位面向数字孪生城市和自然资源统一监管对测绘地理信息的新需求,在全国开创性地开展了面向数字孪生城市的智能化全息测绘试点工作。本文结合上海市智能化全息测绘试点工作,从数字孪生城市、数字孪生城市对地理信息的新需求、智能化全息测绘关键技术及测绘成果等方面展开了论述,重点介绍了智能化全息测绘的技术体系和产品体系,以及在社会各领域的应用成果。

The wave of informatization represented by new technologies such as big data,internet of things,artificial intelligence,virtual reality,cloud computing and intelligent driving has swept the world. The digital world and the physical world are forming two systems of parallel development and interaction,and digital twin technology emerges at the right moment. With the development of internet of things( IOT) technology,the concept of digital twinning has been introduced into the construction of smart cities,which has a profound impact on urban planning,construction and governance. The Shanghai institute of surveying and mapping has launched a pilot program of intelligent perfect-information surveying and mapping for digital twin cities in China,aiming at the new demand of surveying and mapping geographic information for digital twin cities and the unified supervision of natural resources. This paper introduces the new demands of digital twin cities on geographic information,the research progress of key technologies of intelligent perfect-information surveying and mapping,as well as the technical system,product system and applications of intelligent perfectinformation surveying and mapping.
