A drop of ice blue ink falling from the sky turns into the water of the Yellow River. It flows straight down and converges into "ice". The "water" in the center of the site rises from the "ice surface" and solidifies into ice. In the past, the history of the host city of the 23rd Winter Olympics flashed back on the "ice cube" under the carving of 24 "laser knives", and finally settled as "2022 Beijing, China". When the hockey player hits the image hockey, the "ice cube" gradually breaks under the "impact" of the hockey, and a crystal clear five rings of ice and snow "break the ice".
At the opening ceremony of the Beijing Winter Olympics held on the evening of the 4th, through LED ground screen, 60 meter high ice waterfall, ice cube, ice five rings and other devices, using artificial intelligence, AR, 5g, naked eye 3D and cloud and other technologies, the modern Chinese beauty of "few people but not empty, ethereal and romantic" was interpreted with science and technology, presenting a visual feast for the world.
The performance stage of the opening ceremony of the Winter Olympic Games is very special, which is different from the traditional ground screen projection. It is composed of more than 40000 LED modules. The picture quality reaches 16K and the area exceeds 10000 square meters. It is the largest LED ground screen in the world at present.
Not only the image quality and area, but also the snow proof, antifreeze, stability, compression resistance and other characteristics of this ground screen are also world leaders. In months of high-intensity rehearsals and extreme low-temperature rain and snow weather of minus 30 degrees Celsius in winter, the ground display system can still operate stably.
In order to cope with the impact of bad weather and stage vibration, the construction team of "ground display system" has put a special layer of "protective clothing" on the traditional LED screen to highlight the hazy feeling of ice while eliminating the environmental impact and playing a load-bearing role. According to the design requirements, the load of LED screen per square meter must exceed 500 kg.
In the whole opening ceremony, "ice" not only changed with the adjustment of the program, but also increased the interaction with the performers, which became a highlight of the opening ceremony. When flying the "peace pigeon", the children run freely and happily with lovely luminous pigeons and interact with the glittering "stars and snowflakes" under their feet. Where the children go, the snowflakes follow. This magical and romantic experience is realized through AI real-time video special effects.
This is a set of real-time capture and interaction system, which can capture the real-time position and posture of actors, and render the corresponding art effects. Different from traditional dance beauty, with the help of this technology, children can move freely without following the preset route, and have greater expression space and freedom, which can also make the audience more intuitively feel the natural, lifelike and flexible way of performance.
In an interview with the media, Wang zhiou, visual effect director of the opening ceremony of the Beijing Winter Olympic Games, said that it was the first time in the world to use artificial intelligence technology to dynamically capture so many actors one by one and perform real-time interactive performances on a venue of more than 10000 square meters.
Flying the "dove of peace", raising the Olympic rings and lighting the main torch have always been classic links in the opening ceremony of the Olympic Games. At the opening ceremony, these links condensed the creative crystallization of the creative team. The allegory and beautiful pictures of "the water of the Yellow River comes up from the sky" and the "ice breaking" of the five Olympic rings surprised many Chinese netizens. "It has scientific and technological content, cultural charm and cool modern sense." Zhang Yimou, general director of the opening ceremony of the Beijing Winter Olympic Games, commented on the creativity of this link.
In the impressive "five rings of ice and snow" program, the "Yellow River water" surges and flows on the stage, showing a magnificent "landscape painting". It is known that the water flow image in the program is through the image processing algorithm, the machine "learns" a large number of traditional Chinese ink paintings, establishes the ink texture feature model, and generates the stylized landscape image; In the "ice cube" sports theme animation, the design team painted the human figure in two forms: rice paper ink hand painting and digital ink brush, and extracted the internal "expression" and "wonderful meaning" of the sports human figure with the traditional Chinese method of "viewing images and taking meaning". This combination of ink art and digital technology integrates Chinese culture into the classic scene of the rise of the five rings, with both Oriental heritage and modern scientific and technological expression.
The world's largest LED ground screen, actors move freely on the "ice surface" of the stage, "ink and water ice cube"... The opening ceremony of the Beijing Winter Olympic Games shows a different kind of Chinese romance with the stroke of modern science and technology, and also tells the story of the renewal and upgrading of China's science and technology.
