Wang Jingxian: What "black technology" does "Xue Ruyi" contain?

Chongli, February 4 , In the global all-media live broadcast of the "24 Hours of the Winter Olympics" of China News Network, Wang Jingxian, deputy director of the second division of venue construction of the Planning and Construction Department of the Beijing Winter Olympics Organizing Committee and manager of the facilities of the ancient poplar stadium group, said that the construction of the National Ski Jumping Center contains many "black technologies".

The ski jumping center is a device for athletes to slide through their own gravity before taking off, and is a very important equipment and facility unique to ski jumping. Wang Jingxian introduced: "This speed skating track is a speed skating track in all seasons, not only can you achieve ski jumping in winter, but also because there are ceramic pieces inside, you can also realize the summer ski jumping sport after water injection." In this way, we can achieve our four-season operation and four-season ski jumping purpose. ”

The application of 360-degree surround photography to ski jumping around the world is another "black technology". "Near the jumping point of our athletes, a set of circular cameras will be set up, which can freeze the picture at the moment of the athlete's jump, and through 360-degree 4G images, the audience can see the all-round performance of the athletes' take-off." Wang Jingxian said.

It is reported that this is the first time in the world that such a broadcast screen has been used in ski jumping projects. At the same time, the venue is also designed with "flying cats", that is, through some steel cables, from the perspective of the air, overhead shooting athletes to jump, all the way to the whole process of flight and landing.

Wang Jingxian said that the use of "black technology" provides ordinary people with convenient conditions for ice and snow sports, which greatly increases the opportunity for the urban population with Beijing as the core to enjoy mountain venues. This also greatly improves the opportunities for the entire city to participate in skiing, as well as the city to use the ancient poplar tree complex. (End)
