Guili He, Vice President of China Information and Communication Research Institute, officially released the “Digital Twin City Research Report”. It is reported that this is the most authoritative, comprehensive and pragmatic report in the field of digital twin. This report is based on the urgent needs of digital twin city planning and construction.

The book comprehensively refines the best enterprises at home and abroad from the three aspects of key technologies, core platforms and application scenarios, and the construction of digital twin. It is also the industry’s first research report that is both theoretical and practical.

The Digital Twin City Research Report is a comprehensive study of the Institute of Geographical Sciences and Natural Resources of the Chinese Academy of Sciences, the Research Center for Ecological Environment of the Chinese Academy of Sciences, the Guangzhou Institute of Electronic Technology of the Chinese Academy of Sciences, the National Internet Emergency Center, China Telecom, China Mobile, China Unicom, Tencent, 51VR and CETHIK Group Corporation. These authoritative institutions and enterprises have invaluable guiding significance for leading the digital twin construction.

The digital twin construction boom has arrived

“This white paper, combined with the actual needs of local governments and related industries, will help to promote the full implementation of digital twin cities.” Guili He mentioned in the report.

Compared with traditional smart cities, the report refers that digital twin cities have added urban information model platforms based on IoT platforms, big data platforms, and applications. It not only has the basic functions of the urban space-time big data platform but also becomes a comprehensive information carrier that portrays a city’s every detail. So, it can be used to foresee the future trend of a city.

In addition, the report proposes that in the field of urban governance, several digital super-applications are being formed, such as spatial analysis and effect simulation of urban planning, interaction design and simulation construction of urban construction projects, and urban normal operation monitoring.

Relying on the spatial and temporal trajectory of urban development can deduct the future evolution of the city, thus implementing accurate policy support for the government. For example, urban traffic flow and signal simulation can optimize a city’s traffic. Disaster simulation can make the city emergency plan closer to the actual situation.

Since the introduction of the concept of digital twin, it has aroused widespread concern in domestic government, industry, research and development, and has been ignited in research and construction.

● In 2018, Hebei Xiong’an New District Planning Outline pointed out: Adhere to the simultaneous planning and simultaneous construction of digital cities and real cities and build a digital city with deep learning ability and global leading. At present, Xiong’an New District is fully promoting the construction of BIM management platform;

● In 2019, Guiyang City proposed to build a digital twin city from the small-scale urban ecosystem such as super-large community governance and neighborhood streets;

● Nanjing Jiangbei New District is making efforts to promote urban development towards an intelligent and advanced form, and strives to build the “National Digital Twins First City” by 2025;

● Zhejiang Province released the pilot implementation plan for future community construction, formulated nine scenarios of “future community”, and proposed the requirements for building realistic and digital twin communities;

● Zhoushan City, Xixian New District, Chongqing City, Yangtze River Delta Integrated Demonstration Zone, and other places have adopted the construction concept and model of digital twin cities, and have developed the top-level design and planning of smart cities, and promoted the construction of smart cities with digital twin cities as the guide.

Nowadays, the construction of digital twin cities has entered an implementation period. Relevant investments have maintained rapid and steady growth.

According to data released by IDC’s Global Semi-Citizens’ Smart City Expenditure Guide, China’s smart city technology investment reached US$20.8 billion in 2018, an increase of 20.2% compared to 2017’s US$17.3 billion, which is the world’s second-largest. IDC predicts that China’s smart city technology-related investment will maintain a compound annual growth rate of 19.3% in 2016–2021.

Under such a background, a group of technology companies with strong innovation capabilities and outstanding business products are focusing on advanced technologies such as BIM, CIM, VR/AR and AI, and are working on the field of “digital twin” and have applied it to multiple industries.

“Technological innovation will definitely break the existing industrial structure of smart cities, prompting the industry to reshuffle, and new unicorns will appear.” Guili He mentioned at the meeting.

The report specifically mentions the practice of 51VR in the digital twin industry, and the scientific and technological achievements have aroused attention from the industry.

51VR uses technology to help digital twin construction

The report mentions 51VR’s contribution to the digital twin field. For the rapid modeling and automatic parametric modeling of the city, the report pointed out that 51VR can quickly and automatically build large-scale digital data using GIS, UAV oblique point cloud, satellite image, street view, and other technologies and data.

The twin city model restores every detail of the city and performs dynamic real-time rendering of large scenes to realize the visualization and refinement of urban operation management based on data visualization and scene visualization. 51VR implements digital twin technology to restore a whole city; through space-time data dynamic weather and lighting, the construction of thousands of square kilometers of L2-level digital twin cities in about 6 hours.

The report mentioned that the domestic technology companies have improved the visual rendering of digital twin scenes by self-developing cloud rendering PaaS architecture, real-time rendering and physical simulation technology.

Besides, the report also writes about the rapid development of domestic original simulation software in recent years.

The report pointed out that domestic simulation software has formed certain advantages in some areas such as transportation and some technology companies have already had some achievements. 51VR is one of them.

51Sim-One, independently developed by 51VR, is an autonomous driving simulation platform. It can integrate data from different sources through its high precision map editor and conversion tools, which can quickly turn unstructured data into high realistic and structured virtual scenes. It also has an evaluation system to review every task during the process of training an autonomous driving vehicle, which greatly improves efficiency.

The construction of digital twin cities has just begun. Compared to traditional smart cities, digital twin cities require many technologies such as mapping, geographic information, semantic modeling, simulation, intelligent control, deep learning, collaborative computing, virtual reality, and higher requirements on IoT, AI, and edge computing. The opportunity is great but with challenges.

As predicted in the report, when the construction of digital twin cities is deeply implemented and perfection, future life will undergo profound changes. 51VR will continue to make breakthroughs in the key technology of digital twin, and put core application scenarios into practice. We hope to build an eco-system with the industry’s outstanding institutions and enterprises.

Let’s take a look at the experts of the 51VR who attended this conference. They are Dr. Zhang Fan, Product and Business Manager of 51VR Intelligent Vehicle and Transportation Division, Liu Xiaolun, Director of 51VR Digital City Division, and Kang Jinyang, 51VR’s Smart City Senior Partner.
