As the "highlight" during the Spring Festival in the Year of the Tiger, watching the 2022 Beijing Winter Olympics is or will become one of the necessary rituals for most people to celebrate the New Year. However, due to the normalization of the prevention and control of COVID-19, it is a pity that the Winter Olympic Games held at the "gate of home" could not be observed at a close distance.

In fact, during the 2022 Beijing Winter Olympic Games and Winter Paralympic Games, no matter where you are, you only need to have a 5G environment to enjoy the "exclusive" event broadcast through free interactive technology. You can not only be your own guide, but also freely choose the viewing angle.

A few days ago, Chen Baoquan, the person in charge of the ice and snow project interactive multi-dimensional spectator experience technology and system project, the key project of the national key research and development plan "Science and Technology Winter Olympics", and the executive director of Peking University Frontier Computing Research Center, visited the People's Ice and Snow · Ice and Snow Technology Talk, and gave a detailed introduction to the ice and snow project interactive multi-dimensional spectator experience technology and system project.

Chen Baoquan said that watching the game through interactive VR rebroadcasting technology is different from the experience of watching the game on the spot, and the effect will be better. "Because going to the scene is to watch from your seat, your perspective actually has some limitations. Relying on our research and development of the ice and snow project interactive multi-dimensional experience technology and system, we have successfully endowed the audience with the magic of" separation ", so that everyone's seat and perspective can be" called to transfer "at any time along with the hot spot of the event. Everyone can change their viewpoint to watch the event according to their own wishes, and can see high-definition images, which can bring a better viewing experience. "

When talking about the technical support behind this immersive experience, Chen Baoquan proposed that improving the resolution can ensure "seeing clearly", and good clarity can bring a better sense of reality. "I think the most important thing of 'seeing clearly' is to give the audience a real sense of the scene. 'Seeing really' means that we can change the view space at will. In order to ensure that the audience can watch the game 360 degrees without dead angle and comprehensively present the changes of the hot spots on the field, the interactive multi-dimensional viewing experience technology and system of the ice and snow project use more than 40 to 60 cameras to shoot around the field. Multiple video signals have been processed to generate more viewpoints, forming a mass of videos that converge to the mobile phone. " He said.

At the same time, Chen Baoquan also proposed that this technology can achieve 360 degree all-round viewing, and help the audience to achieve a free perspective. "Free viewpoint is to generate and calculate the middle viewpoint of the captured video, so that the audience can have a seamless experience when crossing or rowing in the field. It is like walking slowly in this field, you can also see the corresponding image in every instant and every viewpoint."

"We can put the experienced guidance strategy into the system in advance, similar to AI technology, so that we can provide a special degree of freedom viewing mode according to the free viewpoint. We can combine such an intelligent guidance technology with the free viewpoint generation technology, and the system will generate some wonderful clips in real time. These clips can be switched in by means of video stream, so that everyone can 'lie flat' to watch. "

When introducing the value of the interactive multi-dimensional experience technology and system for ice and snow sports events for on-site viewing, Chen Baoquan said that there is inevitably the limitation of the point of view of the on-site audience, and a mobile phone can break this limitation. For example, an event was in front of the audience at the beginning, and then the point of view shifted to the opposite field. At this time, the audience can take out their mobile phones to adjust their viewing posture, which also realizes a complementarity and integration of reality and fiction. There is also a particularly important function at the scene, that is, there are often some disputes when the referee makes a decision. The free perspective can provide a comprehensive perspective for the judges on the scene to study and judge, which will also play a good role in all aspects.
