ultra high contrast, 3840Hz ultra high refresh rate, and 29900×15096 ultra high resolution ultra high definition gorgeous picture.Equipped with boe’s independently developed super-large display module control and synchronization system, it can also capture the actors’ moving track in real time to achieve seamless interaction between the screen and the actors.It should be noted that the ground display system can still achieve stable operation in the 5 months of high intensity rehearsal and the extreme low temperature rain and snow weather of minus 30 degrees Celsius in winter, which shows its stability and reliability.”We have spent three years, with ‘digital technology’ as the carrier and ‘combination of tradition and innovation’ as the intention, to create a bright dream of ice and snow artistic conception around the main torch platform, and tell the world the story of Chinese culture in the new era with visual art,”Wang Zhiou, director of visual effects for the opening ceremony and director of visual effects production team Blackbow, said that the presentation of these visual content requires a high degree of coordination and perfect cooperation with hardware technology.The world’s leading display technology and wisdom system, so that the opening ceremony of the creative content to achieve the best presentation effect.During the opening ceremony of the Winter Olympics, the show “Snowflake” was impressive.The snowstorm dissipates under the skaters’ feet, and more than 600 children laugh and play on stage like glittering snowflakes.These impressive figure: xinhua new media, is the national stadium of Intel’s camera, then video signals to the edge of computing system for three dimensional reconstruction and rendering, then the generated artistic image rendering on the LED screen, and with a strong work force to ensure that the actors interact with domestic artistic image in real-time and fluency.This is the first time in the world that more than 600 people can interact with each other in real time in such a large venue.The same technology was used in “Salute to the People.”Through the real-time interaction between the actors and the large screen laid on the scene, the smooth effect that could not be achieved only by rehearsal was achieved, and the aesthetic art and Olympic spirit were transmitted to the world.The reason to achieve such a cool program effect, is based on its Xeon scalable processor 3DAT technology, joint third-party professional team customized development of the “performance real-time special effects system based on artificial intelligence technology”.According to introducing, on coverage, Intel relies on advanced AI algorithms specifically designed and developed the model of multiple human body detection AI hundreds of actors can consistently accurate identification field, real-time output using camera calibration results more their true location information, only in the 4 cameras cover full and complete the information collection is done.In real time, the data signals collected by the camera are transmitted to the edge computing system equipped with the third-generation Intel Xeon scalable processor in the National Stadium through optical fiber. Its powerful computing power can meet the real-time, massive and high-precision graphics, image processing, 3D modeling and data analysis requirements.In terms of transmission efficiency, “Real-time special effects system for performance based on artificial intelligence technology” was developed by Intel OpenVINO visual tool suite and enabled by Intel DL Boost technology to achieve accurate, smooth and real-time video data reading and processing, from image acquisition, recognition to detection and processing.It takes less than a few tens of milliseconds.”I don’t want to define technology as an adjunct to art, but more and more it’s an important part of art.”Beijing Olympics and the winter paralympic games opening and closing ceremonies zhang yimou from the Angle of artistic creation, affirmation of the role of innovative technology, “like the winter Olympics opening ceremony of the people and” lake “, “snow” interaction, the effectiveness of the fluid is not rehearsed alone would achieve, help us to realize the creative and innovative technology, it makes art play a greater charm.”The opening ceremony is undoubtedly a wonderful and unsurpassed audio-visual feast.The global audience can enjoy such a great event of the Winter Olympics, also cannot do without powerful, highly reliable communication network services.According to China Unicom (600050), the communication guarantee task of the opening ceremony involves eight special tasks, including fixed communication, mobile communication, fireworks, emergency communication, public intercom, security inspection greenhouse, video retransmission (OBS), 5G innovation, as well as daily office communication service guarantee of the headquarters.In this regard, China Unicom ensures that all nodes are connected with optical cables using double routing and double uplink, and guarantees 471 special lines of various types, 115 fixed phones and wireless fixed lines, 241 POC terminals, 495 WiFi points, 85 base stations, 895 room points, 1692 OTN network points and 301 OIN network points.Comprehensive wiring 3032.At the same time, China Unicom has opened two emergency communication vehicles, laid more than 45 kilometers of temporary optical cables of various types and more than 1,800 pieces of horse roads, and provided key support for pipeline equipment such as long-distance backbone network optical cables, CCTV image and video transmission optical cables, and optical cables carrying the major customer business of the Winter Olympics reprotection.
