The laser pillar of light rushes into the sky, writes "One Under heaven" on the cloud, and displays the "Five Rings" logo in the cloud.
On the evening of February 4, the opening ceremony of the Winter Olympics was held at the Beijing Bird's Nest. Shenzhen, located on the coast of the South China Sea, also interacted with the opening ceremony through the form of a connection. As a young city of scientific and technological innovation, a large number of scientific and technological elements with Shenzhen characteristics appeared at the Scene of the Winter Olympic Games, and high-tech such as digital snowflakes, AI robots, drones, and laser projections amazed the audience, bringing an audiovisual feast to the audience.
"Shenzhen Elements" helps the Winter Olympics of science and technology. As early as the beginning of the preparation for the Winter Olympics, the Ministry of Science and Technology jointly studied and formulated the "Science and Technology Winter Olympics (2022) Action Plan" in conjunction with relevant departments, focusing on 8 aspects such as "zero-row energy supply, green travel, 5G sharing, smart spectators, sports science and technology, clean environment, safe competition, and international cooperation", and specially set up key special projects for the "Science and Technology Winter Olympics", and approved the launch of 80 "Science and Technology Winter Olympics" projects, making the Winter Olympics full of science and technology.

Drones and laser projection "fancy" appeared
Under the background of "carbon peaking", how can Shenzhen enterprises help carbon neutrality at the Winter Olympics? The drone performance provided by Shenzhen Gaoju Innovation Technology Development Co., Ltd. (hereinafter referred to as "Gaoju Innovation") and the "writing on the cloud" from Shenzhen Guangfeng Technology Co., Ltd. (hereinafter referred to as "Guangfeng Technology") are worth mentioning.
On the evening of February 4, after the warm-up performance, the topic of "it snowed in Shenzhen during the Winter Olympics" once appeared on Weibo's hot search, brushing the circle of friends of Shenzhen people. It turned out that this was the "highlight" drone show in the warm-up performance. The 2022 drones posed the image of the winter Olympic mascot ice pier and snow melting, and also simulated snowflakes falling.
Behind the "Shenzhen Snow" screen, each "snowflake" not only does not consume electricity, but also reduces air pollution. Li Chenliang, general manager of Gaoju Innovation, introduced that the drone model used in this performance has a long endurance of 33 minutes, supports multiple take-offs and landings to save energy and save electricity, and can also pause, rewind and return at any time, and can react according to the director's needs at any time during the rehearsal of the program, which greatly reduces air pollution compared with traditional fireworks.
In addition to the drone show, the highlights of the Shenzhen warm-up show included laser floodlights that could write on clouds. Four dazzling laser light pillars rushed into the sky, wrote "One In the World" on the cloud, and displayed the "Five Rings" logo in the cloud, which was very visually shocking. The traditional projection distance is generally within 500 meters, why can the font on the warm-up performance be presented in the cloud? Zhang Feng, general manager of Guangfeng Science and Technology Engineering Division, told Nandu reporter that the technology used this time can be imaged within a range of 30 meters to 3000 meters, and the highest brightness of similar products in the industry is currently 60,000 lumens, and the brightness of the flood lamp reaches 100,000 lumens, so long-distance imaging is also visible to the human eye.
For helping carbon neutrality, Zhang Feng said that the traditional technology has low electro-optical conversion efficiency, large heat generation, the need for a larger heat dissipation device, large volume, and the new technology used this time can greatly improve the electro-optical conversion efficiency, greatly reduce heat loss, so as to be more energy-saving and more environmentally friendly.
UBTECH Technology
AI+ robots power ice and snow sports
In the warm-up performance of the Shenzhen branch venue, the collective dance performance brought by 56 robots was very eye-catching. Dressed in the traditional costumes of 56 ethnic groups, they waved the national flag and the Olympic flag to cheer for the Olympic athletes. In addition, there are 9 robots transforming into skiers and skaters. They presented the aerial skills of the two classic sports of snowboarding and skiing, while taking into account the movements, simulated the expression of the athletes during the competition and maintained stability, restoring the cool and heroic posture of the Olympic athletes.
These robots come from Shenzhen's artificial intelligence and humanoid robot company UBTECH. It is worth noting that the skis of the 9 "skier" robots are also full of "Shenzhen elements". Li Chao, commercial director of UBTECH Technology, introduced that the hand-painted design of the skis combines Shenzhen landmarks and scientific and technological elements, and there are patterns of Shenzhen landmarks such as civic centers, Ping An Building, and talent parks on the skis, as well as pioneering cattle representing the spirit of Shenzhen. In addition, the designers have also drawn flexible line patterns and space patterns, giving them a full sense of technology.
HUAWEI CLOUD, Tencent
Virtual Beauty Anchor Sign Language Broadcast
At the opening ceremony, the last torchbearer put the torch into the center of the "snowflake shape" and became the main torch, the small flame is also transmitting the concept of low carbon, and the "snowflake shape" also closes the distance between people and the ice and snow world. While many viewers were affected by the epidemic and could not come to the scene in person, CCTV cooperated with HUAWEI CLOUD to launch a "digital snowflake" that can be customized by everyone, so that more people can participate in the Winter Olympics through digital technology.
Nandu reporter learned from HUAWEI CLOUD related aspects that "Digital Snowflake" is based on HUAWEI CLOUD MetaStudio digital content production line, and took the lead in using cutting-edge cloud computing technologies such as media AI, virtual ID, cloud rendering, and blockchain, which can generate a unique "digital snowflake" image and obtain a special certificate of "My Winter Olympics Digital Snowflake".
It is understood that the use of AI image recognition technology, through HUAWEI CLOUD's Pangu CV model based on 100 billion parameters, accurately identifies the face in the user's photo in milliseconds to generate a personalized digital snowflake image, and also integrates the Chinese national essence - Peking Opera Face, generating a unique Peking Opera face image based on the user's face.
It is also worth mentioning the virtual beauty anchor with a vocabulary of more than 1.6 million and sign language, and she also witnessed the birth of the first gold of the Chinese team. "The Chinese team, take the lead in crossing the finish line!" On the evening of February 5, after the relay final of the short-track speed skating mixed team, the anchor of CCTV AI Sign Language And sapiens "Listening" used accurate sign language to convey the wonderful content of the Beijing Winter Olympic Ice and Snow Event for the hearing impaired, expressing the excitement of witnessing the Chinese team winning the "first gold".
This virtual beauty anchor "Listening" was also born in Shenzhen and was created by Tencent's technical team. The relevant person in charge of Tencent said that behind the "listening" integrates multi-modal interaction technology, 3D digital human modeling, machine translation, speech recognition and natural language understanding and other technologies, making her her sign language expression ability very close to that of real people. Up to now, the vocabulary and sentence coverage of "listening" has exceeded 1.6 million, and a lot of directional optimization has been made for sports events, and the sign language is understandable by more than 90%.
