Beijing Winter Olympics opening ceremony screen: naked-eye 3D + dynamic capture, the world's largest LED stage

The ground screen at the opening of the Beijing Winter Olympics presented a wonderful visual feast for the audience. It is composed of 46504 50 cm square unit boxes, with a total area of 11626 square meters, which is currently the world's largest LED stage.

Don't look at the large area, the floor screen is very "smart".

For example, the scene of the water of the Yellow River coming up from the sky, the water flowing down from the ice waterfall, the turbulent waves on the earth screen seem to be rushing in, layered on top of each other, bringing people an incomparably shocking feeling. Wang Dingfang, project manager of the opening ceremony of the Winter Olympic Games of Leyard Group, introduced that the overall ground screen can present a naked-eye 3D effect. In addition, there is a circle of "black field" around the screen, in fact, it is also a screen, such as when the snow falls, it is flipped in this area, giving people the visual effect that the snowflakes are scattered one after another. The ground screen also has a motion capture interactive system, in the bird's nest "bowl mouth" installed camera, can capture the dynamics of people on the ground screen in real time, to achieve dynamic capture, such as the actor skiing on the ice screen scene, the actor "slide" to where, the snow on the ground has been pushed away, and then such as the peace pigeon display link, children play on the ground screen snow, where there are snowflakes, dynamic capture system not only optimizes the scene, but also makes the scene more realistic.

"At the opening ceremony of the Winter Olympics, our entire project includes the ground screen, ice waterfall, ice cube, north-south stand screen and playback system and other devices, and multiple display screens display a complete picture as a whole, and then cooperate with actors, visual effects, lighting and choreography to present a Beijing Winter Olympics theme of 'pure ice and snow, passionate dating'." Liu Haiyi, the general manager of the Winter Olympics project of Leyard Group, introduced that the entire ground screen LED of the playback system is responsible for displaying 4 8K playback materials, the ice screen is responsible for displaying 2 8K playback materials, and the ice cube is responsible for displaying 1 8K playback material, and then cooperate with the broadcast control system to achieve multiple player video output synchronization, with an error of no more than 2 frames.

In the 2019 National Day Ceremony, the 2008 Beijing Olympic Games, the centenary of the founding of the Party "The Great Journey" theatrical performances, the previous Spring Festival Gala and other major occasions have Leyard's figure, compared with the past, the opening ceremony of the Winter Olympics for the first time used the system four backup and pixel four backup to ensure that there is no mistake. Li Jun, chairman of Leyard Group, introduced that the system four backup means that the system equipment are designed for rapid disassembly structure and docking mode, in addition to providing the necessary spare parts for the system, for rapid replacement, the control equipment of the LED display system is also all using dual-machine fully redundant hot backup mode, to ensure that during the operation of the system, once the main equipment fails, the backup equipment can be immediately automatically or manually switched online to fully ensure the stable operation of the system and no downtime. Pixel four backup means that each display pixel has made a pixel backup, a display pixel with 4 3-in-one SMD lights to do mutual backup, the four LEDs as a pixel, that is to say, each pixel is four LEDs at the same time backup, any LED point is bad, will not affect the normal display of individual pixels, any set of data control chips have problems, the pixels of the set of LED areas will not be completely black, each pixel also has 2 LEDs normal display.

The entire project cycle of the opening ceremony of the Beijing Winter Olympic Games spans the summer and rainy seasons in Beijing in July and August, and the winter and snow seasons from December to February of the following year, how to ensure that the LED screen can not only experience sun exposure and rain erosion, but also bear the erosion of autumn wind and sand and winter ice and snow? Li Jun introduced, according to the opening and closing ceremonies of the site application of large area LED display modules face the complex internal and external environment, they research and development of waterproof, anti-slip, anti-glare, high load of high-performance LED display modules, can adapt to outdoor low temperature freezing and other extreme environments, LED display and its components all meet the IP66 protection standards, completely prevent the intrusion of foreign objects, withstand strong water spray when the amount of electrical water will not produce harmful effects.

In addition to the big screen at the opening ceremony, the big screen of Leyard is actually around you. Li Jun introduced that in the implementation of the "100 cities and 100 screens" ultra-high-definition video landing promotion activities in Beijing, Leyard provided 9 outdoor 8K ultra-high-definition displays for the live broadcast of major events such as the Winter Olympics, so that the audience can immerse themselves in the atmosphere, such as Shougang, Pinggu Jinhai Lake, Badaling parking lot and other places, you can also go to these places to experience the wonderful moments of the Winter Olympics through the ultra-high-definition screen.
