Technology Highlights of Beijing Winter Olympics


BEIJING – International Olympic Committee (IOC) President Thomas Bach told the global media at the Alibaba Cloud ME booth on Sunday. The Beijing Winter Olympics are unprecedented in the application of technology and are expected to be widely used around the world.

The booth an innovative cloud-based technology that uses photorealistic reality, both inside and outside the closed loop of the official Beijing 2022 venue. Allowing participants and fans to experience mixed reality social interactions.

Relying on the low-latency, high-availability, and high-concurrency features of Alibaba Cloud. live video can projected onto a remote 4K high-definition screen to generate a realistic holographic effect. And all details can be reconstruct in high-definition – including, according to the introduction on the International Olympic Committee website, Micro-facial expressions and clothing textures – which are essential for face-to-face interactions.

From the opening ceremony of the Beijing Winter Olympics on Friday, all kinds of high-tech have been seen and amazed.

“We decided about two years ago that we would rely more on modern digital technology. Its chemistry with performers than on huge crowds,” said Chang Chang, director of the opening and closing ceremonies of the Beijing 2022 organizing committee. Yu said.

Under the background of 5G, artificial intelligence, and the Internet of Things, the National Stadium. Known as the “Bird’s Nest”, has undergone intelligent transformation to host the opening and closing ceremonies. For example, digital technology applied to equipment operation. Energy management and environmental quality control, providing favorable conditions for the ceremony.

“Inside the Bird’s Nest, we built digital workstations and rendering studios to generate visual effects on the fly. Completely upgrading it from a traditional building to a smart stadium,” Zhang said.

According to Wang Zhiou, the visual effects director, the entire floor of the Bird’s Nest uses high-definition LED technology instead of traditional projection, with 16K image quality. At the same time, the audience also experienced the comprehensive application of AI, AR, naked eye 3D and other technologies.

According to Zhang Yimou. The chief director of the ceremony, the actors movements can be captured in real time through the screen on the floor. So as to realize the interaction between the actors and the screen. “We actually talked about this technology at the opening in 2008, but it wasn’t possible at the time.”

In the “Dove of Peace” session, no matter where the children ran. However, the snow under their feet followed, which had a strong attraction to the audience. Rather than a pre-designed snow effect, Chang said, it uses real-time capture, rendering and playback.

“It’s not the latest technology. But it’s very rare to achieve such a large-scale application in such a large live plaza show,” Chang said.

What’s more, cutting-edge technology widely use in venues and events.

For the first time in the history of the Olympic Games. Carbon dioxide refrigerant introduce to make the “fastest” ice weather forecast radar equipment and weather tracking stations established in the two mountainous areas of Yanqing and Zhangjiakou. Forming a weather monitoring network, realizing minute-level, spatial and temporal dimensions. Furthermore, accurate weather forecast with a dimension of hundreds of meters, the Olympic broadcast service is based on 5G.

Eleven venues for the 2008 Olympics repurposed to reduce emissions, reduce environmental impact, and minimise water, energy and material consumption.

All competition venues powered by 100% green electricity, and clean energy vehicles account for 80% of the total competition vehicles.

Zhangjiakou has put into use 655 hydrogen fuel vehicles to provide transportation and logistics support services during the Olympic Games. Hydrogen-fueled vehicles can be refuel quickly and start at a low temperature of minus 30 degrees Celsius. Each car traveling 10,000 kilometers can reduce carbon dioxide emissions by about 11.8 tons.

“First, our hydrogen energy vehicle is energy-saving and environmentally friendly; second, it is safer; third, it is suitable for high altitude and cold areas; fourth, its cruising range is quite long.” Zhangjiakou bus driver Xie Yinglong said.
