Behind the "most dazzling ice surface" of the Winter Olympic venues: the team has overcome more than 1,300 problems in half a year

Since the start of the Winter Olympic Games, the naked-eye 3D ice projection show on the five ice venues of the National Aquatics Hall, the National Gymnasium, the Capital Gymnasium, the Wukesong Gymnasium and the National Speed Skating Hall has attracted attention, and the creative design content and wonderful and cool projection effect have amazed the audience.

"Ice projection takes digital imaging to new heights." As the official sports display and award ceremony service sponsor of the Beijing 2022 Winter Olympic and Paralympic Winter Games, the relevant person in charge of the Beijing Olympic Group said that the ice surface of the competition will be used as a fantasy light and shadow performance screen on the beijing Winter Olympic Games, which will enhance the viewing of the event through scientific and technological empowerment, display the cultural connotation of the host country, and reflect the high integration of Beijing's scientific and technological innovation and cultural creativity.

It is understood that under the guidance of the Beijing Winter Olympic Organizing Committee, Beiao Group gave full play to the experience of crystal stone digital technology company in serving the digital image production of the 2008 Beijing Olympic Games and the 2012 London Olympic Games, and realized the first large-scale application of ice projection technology in the Winter Olympic Games. Combining the characteristics of the ice and snow project and Chinese cultural elements, the producers integrated digital technology, with light as the pen and shadow as ink, to create the "most dazzling ice surface" of the Winter Olympics, so that the audience and the audience watching the broadcast could enjoy the cool naked-eye 3D ice image, and immerse themselves in the passion of the Winter Olympic Games and the charm of Chinese culture.

The high resolution of ice projection must be closely integrated with a variety of different shapes of the field to achieve stereoscopic vision at specific angles, and it is also necessary to set specific theme animations and color systems for different competitions. This is the chapter with the most technical difficulty, the largest audience and the most extensive impact in the Winter Olympic sports display video. Different from conventional image media, ice has differences in density, temperature, and reflective refraction, and it is more technically difficult and more complex to achieve a cool effect of pure three-dimensional naked-eye stereoscopic on the ice surface.

In order to project the best image effect, the project team accurately measured and accurately implemented policies, refining the digital content to each pixel, and closely coordinating with the venue and the refrigeration equipment to ensure the delicate texture and beauty of each picture.

Due to the huge area of the ice surface, it requires multiple projection fusion hardware technologies to form a complete picture. The project team repeatedly communicated and revised, overcame more than 1,300 problems in more than 180 days and nights, and finally successfully completed the ice projection series of works, bringing the audience a magnificent naked-eye 3D visual enjoyment, and showing the world a new height of China's digital imaging technology.

The Beijing 2022 Winter Olympic and Paralympic Winter Games are not only a sports event that attracts global attention, but also a grand event for cultural display and exchange. In the process of serving the sports display and award ceremony of the Winter Olympic and Paralympic Games, Beiao Group is committed to integrating culture, sports and digital technology, innovating display methods, and striving to tell the Chinese story to the world and show the "Chinese wonderful" of the new era.
