Entering the large action capture studio located in the National Animation Park in Binhai New Area, Tianjin, surrounded by over thirty high-definition infrared cameras, action capture actors dressed in specific equipment are performing in the center, and a virtual anime character performing the same action is born on the computer. "This is an action digital twin, using optical motion capture technology. Multiple professional cameras inside the studio capture specific marks on actors' bodies, calculate the character's motion trajectory at a rate of milliseconds, and then transmit the data to a computer to achieve the actions of virtual characters." Cui Shengji, technical consultant of the National Animation Park Public Technology Service Platform Motion Capture Studio, introduced to reporters. The motion capture actor performs in the motion capture shed wearing specific equipment. According to Xinhua News Agency, "digital twin" refers to the technology of using virtual 3D technology to restore static objects, people, and the surrounding environment in reality into a computer, then connecting various sensor data in reality, and finally presenting them through carriers such as AR, VR, or various screens. This concept, which sounds highly technological, has been applied in various fields such as urban smart management and cultural and creative industries. "In the application of digital twin technology, static model digitization is relatively well-known to the public." Cui Shengji said, for example, the construction of virtual cities is to "move" real urban street scenes into virtual spaces through digital rendering, collect and process data, and depict the overall picture of the city, thereby achieving intelligent urban management. Our main technology is dynamic digital twin, such as data analysis of human posture, which can be applied to sports medicine, intangible cultural heritage action digital preservation, etc. Recently, Cui Shengji's team collaborated with the Tianjin Binhai New Area Tai Chi Association to preserve a set of Tai Chi action data. "Through digital technology, these intangible cultural heritage can be preserved," he said. Cui Shengji is checking the virtual image production effect. Cui Shengji, born in 1985, has been working in digital technology for nearly a decade. "I have loved playing games since I was young, but I prefer to explore the technical logic behind games." From game art to the digital technology industry, he has been exploring the digital world. In his view, the digital space extends reality and can more efficiently assist people in solving problems, which has great potential in the digital industry. In recent years, with the development of technologies such as the Internet of Things, big data, and artificial intelligence, the implementation of digital twin applications has become possible, and related technical talents are constantly emerging. Among the 18 new professions announced by the Ministry of Human Resources and Social Security in recent years, digital twin application technicians have been included. This technologically advanced digital new profession has also opened up new employment opportunities for many people. Under the demand orientation of building virtual scenes, professions such as facial contouring, motion capture, and motion capture actors are active in social products and game production. "I am mainly responsible for data editing of virtual images," 22-year-old intern Ding Ming told reporters. He is studying virtual reality and plans to stay in the team to continue working after graduation this year. More than 60% of Cui Shengji's team consists of "post-2000s" like Ding Ming, who rely on their imagination and hands to develop the "new era" in the virtual universe
