Original title: Feeling "Science and Technology Model" in Digital Twin -- Approaching Digital Twin Application Technicians

Xinhua News Agency, Tianjin, March 12 (Reporter Xu Siyu) Walking into the large motion capture shed located in the National Animation Park in Binhai New Area, Tianjin, surrounded by more than 30 high-definition infrared cameras, the motion capture actors with specific equipment are performing in the center, and a virtual animation character doing the same action is suddenly born on the computer.

"This is the action digital twin. Using the optical dynamic capture technology, several professional cameras in the booth capture the specific marks on the actors, calculate the movement track of the characters at the rate of milliseconds, and then transmit the data to the computer to realize the action of the virtual characters." Cui Shengji, the technical consultant of the dynamic capture booth on the public technology service platform of the National Animation Park, introduced to the reporter.

It is understood that "digital twin" refers to the technology that restores the static objects, people and surrounding environment in reality to computers using virtual 3D technology, then accesses various sensor data in reality, and finally presents them by carriers such as AR, VR or various screens. This concept, which sounds like science and technology, has been applied in urban smart management, cultural and creative industries and other fields.

"In the applications related to digital twin technology, the public is relatively familiar with the digitalization of static models." Cui Shengji said, for example, the construction of a virtual city is to "move" the real urban street scene into the virtual space through digital rendering, collect and process data to depict the city's panorama, so as to achieve intelligent urban management.

"Our main technology is dynamic digital twinning, such as data analysis of human posture, which can be used in sports medicine, preservation of intangible cultural heritage movement figures, etc." Not long ago, Cui Shengji's team cooperated with Tianjin Binhai New Area Taijiquan Association to preserve a set of Taijiquan movement data. "These intangible cultural heritage can be preserved through digital technology," he said.

Cui Shengji, the "post-85", has been engaged in digital technology related work for nearly ten years. "I like playing games since I was young, but I prefer to explore the technical logic behind games." He has been roaming in the digital world from game art to digital technology industry. In his view, the digital space extends the reality, can help people solve problems more efficiently, and has great potential in the digital industry.

In recent years, with the development of Internet of Things, big data, artificial intelligence and other technologies, the realization of digital twin applications has become possible, and relevant technical talents are also emerging. Among the 18 new professions announced by the Ministry of Human Resources and Social Security in recent years, digital twin application technicians are among them.

This new digital career full of "science and technology" also opens up new employment space for many people. Guided by the demand for building virtual scenes, the types of work such as face pinchers, dynamic captors and dynamic captors are active in social products, game production and other fields.

"I'm mainly responsible for the data modification of virtual images." Ding Ming, a 22-year-old intern, told reporters that he had planned to stay in the team after graduation this year. More than 60% of Cui Shengji's team are "post-00s" like Ding Ming. They rely on their own imagination and hands to develop a "new world" in the virtual universe, and feel the charm of science and technology and aesthetics intertwined between reality and reality.

The new occupation sees the new trend and vitality of economic and social development. In recent years, the scale of China's digital economy has been expanding. The Report on the Development of China's Urban Digital Economy (2023) released last year shows that the scale of China's digital economy now exceeds 50 trillion yuan, ranking second in the world in total. With the rapid development of digitalization in the whole industry, the demand for digital talents is still growing day by day.

"Digital twin application technology has a great demand for young people, and our company is constantly recruiting." Cui Shengji said frankly that the employment prospects of new digital jobs are very broad, and he expects more young talents to enter the digital "new world".
