Technical principle of digital torchbearer
The digital torchbearer is a virtual image, which can be watched on electronic devices. So there is no possibility of seeing the digital torchbearer directly at the scene. The digital torch is made by combining virtual reality (VR) technology and three-dimensional modeling technology. At the opening ceremony of the Asian Games, the real image of the torchbearer was captured by the camera in real time and transmitted to the computer in the central control room.
Then, according to the posture and movements of the torchbearer, the computer accurately restores the torchbearer in the virtual world and makes it into a digital image. After rendering and post-processing, this digital image has a realistic appearance and expressive force of action.
The realization of digital torchbearer can not be separated from the support of advanced science and technology. Through virtual reality technology, digital torchbearers can be displayed as three-dimensional images on the screen, allowing the audience to experience the wonderful torch relay. The application of this technology not only brings a brand-new viewing experience to the audience, but also shows the perfect combination of technology and sports.
Characteristics of digital torchbearers
There are many ways to realize digital torchbearers. One of them is realized by sensor technology. Sensors can sense the audience's position and action, and interact according to the audience's behavior, so that the audience can interact with the digital torchbearer. For example, when the audience waves their arms or shouts slogans, the digital torchbearers will also make corresponding actions to enhance the audience's sense of participation and substitution.
The process of digital torchbearers lighting the torch is realized by cloud platform and 4D projection technology. The cloud platform transmits the images of digital torchbearers to outdoor project equipment. On the stage of the opening ceremony, the image of the digital torchbearer was projected onto a special light screen through 4D projection technology, forming a realistic virtual human image.
