CCTV news: At this Winter Olympics, a handheld snow temperature snow tester was used. It is called the "just need" of the snow event by the staff of the Winter Olympic Stadium.
This is the handheld snow temperature snow observation instrument, the developer told reporters, this specially customized handheld portable product for the Winter Olympics equipped with infrared temperature measurement, laser ranging, intelligent image and other advanced high-precision sensors, can automatically identify snow, and detect the real-time temperature of snow.
Zhang Liang told reporters that the most suitable ski resort is ice-like snow. Skis that cross the snow surface do not change much, reducing the impact on the next player and ensuring a fair play to the greatest extent possible. 1 hour before each competition and 1 hour after the competition, the snow surface will be measured and positioned in real time using a handheld snow-warmed snow-like observer, and the coordinate data will be reviewed on the online map to meet the needs of refined observation on the field.
