The opening ceremony of the Beijing 2022 Winter Olympics was staged perfectly, and the Chinese presented a romantic feast of ice and snow to the world in their own way. Behind this visual feast, the innovation and strength of Shangxian Technology are interpreted, which is China's unique language for dialogue with the world.

In addition to the still shocking opening ceremony, the Winter Olympics continued to be high-energy and introduced many black technologies, from sports to life to vision, fully demonstrating China's scientific and technological strength!

Black Technology 1: "pie falling from the sky"

The smart restaurant located in the media center of the Winter Olympics has been painstakingly designed and developed. It not only takes into account the problem of gathering and dining during the epidemic, but also reduces the cross-contact between people, the probability of epidemic transmission and the cost of epidemic prevention.

Secondly, the joint application of a variety of black technologies, automation, visualization, and efficient intelligent catering equipment, from meal preparation, cooking, meal delivery service, "one-stop" 24-hour service, so that food can fall from the sky!

After diners scan the QR code on the dining table to order, the dishes will be transported to the top of the dining table through the cloud rail system at the top of the restaurant, descend with the cable, and hover in front of people for their access.

Black Technology 2: Who is the "cheetah" that the whole network is grateful for?

The "Cheetah", which has been on fire recently, is actually poor in the "Ice Ribbon" of the National Speed Skating Arena, the speed skating competition hall, and there is only one set.

This camera, which runs faster than an athlete, was developed by the Central Radio and Television Station for the tracking and shooting needs of large-scale fast straights and cornering sports.

It is dedicated to the broadcast of the Winter Olympics speed skating events, and is a special equipment for live TV, not a referee system camera.

The reason why it is named "Cheetah" is precisely because of its amazing speed, the maximum running speed can reach 25m/s, and the acceleration can reach 3.5m/s, which is equivalent to 90 kilometers per hour, and every move cannot escape the "Cheetah". ” eyes and the micro expressions of the players can be clearly captured.

In addition to tracking the player's position in real time, it can also meet the needs of broadcast to achieve acceleration, deceleration, overtaking and other actions, and flexibly capture the game screen.

Salute to every photographer who has been busy on the sports field! Of course, in addition to cheetahs, the Winter Olympics also developed cone-barrel cameras for speed skating live broadcasts to record the competition from more diverse perspectives.

Black Technology 3: The Metaverse Brings Fire "Virtual Digital Humans"

During the opening ceremony of the Winter Olympics and the course of the event, various hard technologies such as artificial intelligence, 5G, AR, naked-eye 3D and cloud showed their magic power. Among them, the virtual digital human technology, which is the entrance and connection link of the metaverse scene, is particularly eye-catching. The weather anchors and sign language anchors of the Winter Olympics are virtual digital humans.

Zhu Yongquan, a famous CCTV host and "Duanzishou", conducted a devil interview with the AI sign language anchor. As Zhu Yongquan's speech speed increased, the AI sign language anchor performed "afterimage-level hand speed" for us.

Black Technology 4: Exposure of the "Any Door" of the Winter Olympics

IOC President Bach also had a "meeting over the air" with Alibaba CEO Zhang Yong through Alibaba Cloud ME. Through this "arbitrary door", the Olympic Games organizers can "teleport" athletes, event staff, volunteers and media friends to the designated location, thus breaking the physical space restrictions under the epidemic situation and realizing the interaction on the same screen in different places. It is also the first time in the history of the Olympic Games that the cloud-based holographic audio and video communication technology is used to realize cross-scenario remote meeting.
