In the beautiful children's chorus, the torch of 2022 Beijing Winter Olympic Games, which has been burning for 17 days, is slowly extinguished. During the 17 days, there are not only exciting gold medal winning moments, but also the ubiquitous light of science and technology. This is not only a colorful sports feast, but also a dazzling technology exhibition.
8K Ultra HD video, VR viewing and bullet time have brought a new viewing experience to the audience. The all-round capture of "Liebao" and "Eagle Eye" helps the referee make a fair and timely decision. Mixed interview and cloud broadcasting make the event report simpler and more efficient. Unmanned smart canteen and unmanned train with 5G make the event safer.
The Beijing 2022 winter Olympic Games is integrated with the application of digital technology in venue construction, competition broadcasting, event service, and epidemic prevention and control. According to statistics, a total of 212 technologies have been applied in the Winter Olympics. 4 technologies have been launched for the first time in the world, and 33 technologies have been used for the first time in the Winter Olympics. Among them, the most dazzling technology is digital technology.
Digital technology makes the Winter Olympics better
At the opening ceremony, the dreamlike scene of Yellow River pouring down and the dreamy scene of snowflakes following each other like shadows is unforgettable. At the closing ceremony, the green light passed through the torch platform to create a colorful "towering tree", and the red ribbon danced and changed into a Chinese knot. The world's largest Ultra HD LED 3D stage perfectly presents the naked eye 3D effect. AI's motion capture, AR, VR, "true laser" display and other technologies have subverted the traditional stage performance mode and presented a dreamy and realistic beauty of science and technology.
During the competition, Gu Ailing's omni-directional shot of jumping in the air was absolutely beautiful and shocking. The moment when Wu Dajing motioned Ren Ziwei to go first was touching. 8K Ultra HD video clearly presents every game moment, and the smooth and delicate picture brings a stronger visual impact to the audience. The Beijing 2022 Winter Olympic Games has become the first Winter Olympic Games in the history of the Olympic Games to realize the live broadcasting of 8K video technology and the broadcasting of important sports events.
How many turns did Su Yiming make? Are there any violations by short track speed skaters? The application of digital technology makes every wonderful moment of the game perfectly captured by the camera. Thanks to the "Liebao" (Ultra high speed 4K orbital camera system), the whole network can track the position of athletes in real time and capture every wonderful moment flexibly. 360 ° free viewing angle technology uses three-dimensional reconstruction and rendering technology to realize free viewing angle and clearly present each flying and jumping picture.
Digital technology not only provides more convenience for event shooting, but also brings more possibilities for the audience to watch the Winter Olympics. 8K + VR on-demand video allows the audience to immerse and watch the game freely from any angle. "Bullet time" technology enables sports lovers to switch the viewing angle arbitrarily, zoom freely, watch the game in slow motion, and relive the highlight moment of athletes. "Time slicing" technology will freeze multiple action shots of athletes in one picture to better present wonderful moments. AI sign language interpreters provide high-quality AI sign language interpretation services for the hearing impaired.
Digital technology makes events more efficient
Digital technology makes competition venues more intelligent. "Ice ribbon" witnessed the birth of a number of world records. It finely regulated the indoor environment based on digital twin technology, controlled the temperature difference on the ice surface within 0.5 degrees centigrade, and made "ice ribbon" the "fastest ice". The efficiency of "ice ground and basket ground conversion" within 6 hours of "Binglinghua" is amazing. The real-time collection and analysis of equipment energy consumption by the visual integrated command platform saves about 20% of energy consumption. Wearing AR glasses, the on-site maintenance personnel can transfer the situation seen from the first perspective to the support department, realize remote operation and maintenance cooperation, and improve the operation and maintenance efficiency by 40%. This is the first time in the history of the Winter Olympics to combine artificial intelligence with meteorology, so that the refinement of weather forecast in the competition area of snow sports can reach "100 meter level and minute level".
Digital technology makes event reporting easier. The reporters in the interview room on the first floor and the athletes on the third floor come into the same scene and appear in the TV picture in the form of "face-to-face". With the integration of audio and video communication on the cloud and holographic technology, the cross space-time meeting in science fiction films has become a reality. Based on 5G and cloud computing video service system (Info-AV), audio and video processing can be completed remotely in the cloud, reducing the gathering of front-end personnel and improving work efficiency. Compared with the previous Winter Olympic Games, the number of broadcasters of Beijing 2022 Winter Olympic Games has decreased by 40%, but the broadcasting time has increased by 50%.
Digital technology makes events safer. In the smart canteen of the Winter Olympic Village, the ordering and cook are all completed by robots, and the serving also comes from above by robot arms. The canteen can not only operate 24 hours, but also reduce personnel contact. Such unmanned scenes can be seen everywhere in 2022 Winter Olympics. From the torch relay by unmanned vehicles to the driverless high-speed railway train, from the guiding robots and cleaning robots in the competition venues to the unmanned distribution vehicles and unmanned retail vehicles in the Winter Olympic Village, the Beijing 2022 Winter Olympics staged a realistic version of "robot mobilization". In addition, the integration of 5G with Beidou, cloud computing and Internet of things technology optimizes the medical command and scheduling, which races against time for medical treatment, and the intelligent treatment platform improves the level of on-site treatment.
Digital technology has a very promising future
The torch of the Winter Olympics goes out, but the light of science and technology will continue to shine. Digital technology has not only achieved a "simple, safe and wonderful" Winter Olympic Games, but also played a positive role in the high-quality development of economy and society and the improvement of people's living standards in the post Olympic era.
8K program, 8K channel and 8K screen are coming to the public, bringing a new visual experience. The wonderful visual effects brought by AR, VR and naked eye 3D will be used in more scenes such as film and television, games and so on. The "cross time travel" created by mixed interviews and holographic images will be used in more remote activities to create a "zero distance" without meeting. Remote diagnosis and treatment and intelligent dispatching will be used in daily medical first aid to improve the efficiency of diagnosis and treatment. All kinds of unmanned vehicles and intelligent robots will also accelerate their popularization and application in daily life scenes. Many intelligent applications will become an integral part of public life in the future.
The demonstration application of digital technology in the Winter Olympic Games not only breaks through the bottleneck of technological innovation, but also expands the new mode of application, which will promote the accelerated development of related industries. Among the Winter Olympic heritage announced by the Beijing Winter Olympic Organizing Committee, scientific and technological innovation ranks among them. The achievements of digital technology innovation are not only the precious wealth of Beijing 2022 Winter Olympic Games, but also an important driving force to promote scientific and technological innovation and achieve high-quality development.
