It has been 4 days since the opening ceremony of the 2022 Beijing Winter Olympics, but the topic of "Chinese romance" reflected in the opening ceremony is still fermenting and is enjoyed by the public.
Major sporting events have always been the perfect runway for leading technology to debut, and high-tech displays complement sporting events. The Olympic Games are the jewels in the crown of sport, often accompanied by high-tech leading technologies. I still remember the 2018 Winter Olympics in Pyeongchang, South Korea, drones grabbing the camera, and the global debut of 5G networks, unveiling the mystery of 5G in front of global audiences.
The Beijing Winter Olympics have written a new chapter in the era of digital intelligence. This Winter Olympics has not only not been postponed because of the epidemic, but has become a new model for the era of digital intelligence. The opening ceremony of the Beijing Winter Olympics used digital performance and simulation technology throughout the whole process, and through the comprehensive use of artificial intelligence, 5G, AR, naked-eye 3D and cloud and other scientific and technological achievements, the effect of "few people is not empty, ethereal and romantic". The opening ceremony of the Winter Olympics is also the world's first large-scale application of 8K technology to broadcast the opening ceremony live, and the joint 5G network presents an immersive ice and snow visual feast in an all-round way.
Snowflake main torch stand
Simple but not simple
At the opening ceremony, the most high-profile giant "snowflake" shaped main torch platform shone with a crystal clear light and slowly lifted off, accompanied by the ignition of the holy flame, pushing the atmosphere of the entire opening ceremony to a climax, and the global audience was amazed by its aesthetic romance. The main torchbearer of the opening ceremony has a diameter of 14.89 meters, consisting of 96 small snowflakes and 6 led double-sided screens in the form of olive branches, using a double-sided hollow design, embedded with more than 550,000 LED lamp beads, each lamp bead is independently controlled by a single channel driving the chip.
This unprecedented "snowflake" form of the main torch platform, whether it is the overall hardware support or software system, is independently developed and designed by BOE. In order to realize the creative concept that the torch platform of the director group should be like "shining like a diamond", the core R&D team of BOE has developed the narrowest single-pixel controllable special-shaped display product with the narrowest luminous surface in the industry through more than 500 design drawings and nearly 10 rounds of samples, fully presenting the line sense of snowflakes and the delicate picture display effect, and successfully turning the artistic creativity of the director group into reality.
At the moment when the torch is lit, the giant snowflake screen radiates from the center to the surroundings, shining out a wave-like layer of brilliant light, behind the rapid transformation and perfect synchronization of the display screen, the use of BOE AIoT technology system and independent research and development of the same / asynchronous compatible letter and hair system, asynchronous centralized control can quickly send large-scale video content in a very short period of time, synchronous centralized control to ensure that 102 double-sided screens to achieve millisecond response; in addition, "main road + loop" The highly redundant control system backed up ensures the ultra-high reliability of the flare station broadcast control system.
At the same time, by using the LoRa (long-range radio) low-latency control system with synchronous playback time correction technology, it further ensures that the instruction is issued foolproof and realizes the perfect coordination of video pictures.
8K screen
Create a first-class display
At the opening ceremony of the Winter Olympics, the LED screen was a great achievement, showing the perfect combination of China's unique culture and technology under the hands of director Zhang Yimou. The stage floor of the opening ceremony is currently the largest 8K ultra-high-definition ground display system, with an overall area of 10,393 square meters, not only the area is very large, but the technology is also world-class! BOE adopts a number of 8K+ resolution picture fusion technology, ultra-large-scale optical correction algorithm can correct each display screen at the pixel level, can present 100000:1 ultra-high contrast ratio, 3840Hz ultra-high refresh rate, and 29900x15096 ultra-high resolution ultra-high resolution ultra-high resolution ultra-high-definition gorgeous picture.
Through the ultra-large-scale display module control and synchronization system independently developed by BOE, it can also capture the actor's trajectory in real time to achieve seamless interaction between the picture and the actor. At the same time, in the high-intensity rehearsal of up to 5 months and the extremely low temperature rain and snow weather of minus 30 degrees Celsius in winter, the ground display system can still achieve stable operation, and perfectly present the dreamlike and realistic beauty of science and technology to the world on the opening day.
Wang Zhiou, director of opening ceremony visual effects and founder of black bow Blackbow, the general production team of visual effects, said: Under the leadership of general director Zhang Yimou, we spent three years, with "digital technology" as the carrier, with "combination of tradition and innovation" as the intention, around the main torch platform to create a brilliant and dreamy ice and snow artistic conception, with visual art to tell the world the story of Chinese culture in the new era, and the presentation of these visual content needs to be highly coordinated and perfectly coordinated with hardware technology, which is the leading display technology and intelligent system of BOE's industry. Let the creative content of the opening ceremony achieve the best presentation effect.
3DAT technology
Let the actors dance with the snowflakes
At the opening ceremony, the children who played the white pigeon passed by and displayed pieces of snowflakes, and 500 people danced with the snowflakes, and the visual effect was very shocking. The presentation of the snowflake effect is inseparable from algorithms and artificial intelligence. Intel used 3DAT technology based on Intel Xeon Scalable processors and a third-party professional team to customize and develop the "Real-time Special Effects System for Performances Based on Artificial Intelligence Technology", which was applied in the two programs of "Salute to the People" and "Snowflakes" at the opening ceremony of the Winter Olympic Games. With advanced AI algorithms, the whole scene is covered by only 4 cameras, and the actors are allowed to interact with the large screen laid on the scene in real time, achieving a smooth effect that cannot be achieved by rehearsal alone, and transmitting aesthetic art and Olympic spirit to the world.
In terms of coverage, Intel relies on advanced AI algorithms to specially design and develop multiple human detection AI models, which can stably and accurately identify hundreds of actors in the field and output their real location information in real time through 4 cameras. In real time, the camera transmits the collected data signal through optical fiber to Intel's edge computing system equipped with the third-generation Intel Xeon Scalable processor at the National Stadium, which can meet the real-time, large-scale, and high-precision graphics, image processing, 3D modeling, and data analysis needs. In terms of transmission efficiency, the "performance real-time special effect system based on artificial intelligence technology" can realize accurate, smooth and real-time video data reading and processing, from image acquisition, recognition to detection and processing, which only takes tens of milliseconds.
