The huge equipment has a special name &#8211; &#8220;Cheetah&#8221; camera system.<br \/>\nIts design technical standard is 25 meters per second, which is about 90 kilometers per hour.

In the Winter Olympics speed skating competition, athletes can reach speeds of 15 to 18 meters per second, which is about 50 kilometers per hour, while top athletes can reach speeds of 70 kilometers per hour. The &#8220;Cheetah&#8221; design technical standard can reach 25 meters per second, which is about 90 kilometers per hour.<br \/>\nNot only that, &#8220;Cheetah&#8221; can also realize acceleration, deceleration and overtaking actions according to the needs of live broadcast, so as to capture various scenes in the speed skating competition more flexibly and at will.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Why_is_there_no_%E2%80%9Ccheetah%E2%80%9D_in_short_track_speed_skating\"><\/span><strong>Why is there no &#8220;cheetah&#8221; in short track speed skating? <\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-size: 1.125rem;\">Zhao Wei revealed that there is currently only one &#8220;Cheetah&#8221; system, which is installed in the &#8220;Ice Ribbon&#8221; venue. The short track speed skating competition that netizens paid attention to on the 7th did not use &#8220;cheetah&#8221;. Why is this?<\/span><img decoding=\"async\" src=\"https:\/\/www.whatchina.cn\/wp-content\/uploads\/2022\/02\/20220209144753-b0448.jpeg\"\/><br \/>\nAccording to reports, the high-speed track system has certain requirements for the venue. It is necessary to install the track system behind the foam cushions of the athletes outside the stadium, and install the isolation plate to ensure the safety of the surrounding personnel. However, the short track speed skating venue this time does not meet the deployment requirements of the &#8220;Cheetah&#8221;. For the sake of adaptability and safety, the &#8220;Cheetah&#8221; system is not installed in the short track speed skating competition.<br \/>\nIn addition, the referee system and the telecast system are independent of each other. The referee system will arrange some cameras on the scene to shoot key positions in the field or the fouls of players. The referee will refer more to the picture of the referee system, rather than the live picture we see on TV.<\/p>\n<figure style=\"width: 550px\" class=\"wp-caption alignnone\"><img decoding=\"async\" src=\"https:\/\/www.whatchina.cn\/wp-content\/uploads\/2022\/02\/20220209144755-9e0c2.png\" alt=\"Cone camera developed for speed skating live broadcast\" width=\"550\" height=\"310\"\/><figcaption class=\"wp-caption-text\">Cone camera developed for speed skating live broadcast<\/figcaption><\/figure>\n<div class=\"37c28470d9d6d3cb9ff74e663adb766a\" data-index=\"2\" style=\"float: none; margin:0px 0 0px 0; text-align:center;\">\n<script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3594734025006597\"\r\n     crossorigin=\"anonymous\"><\/script>\n<\/div>\n\n<div style=\"font-size: 0px; height: 0px; line-height: 0px; margin: 0; padding: 0; clear: both;\"><\/div>","protected":false},"excerpt":{"rendered":"<p>In the Winter Olympics speed skating competition, athletes can reach speeds of 15 to 18&#8230;<\/p>\n","protected":false},"author":1,"featured_media":19524,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"ngg_post_thumbnail":0,"footnotes":""},"categories":[84],"tags":[2276,2274,2275],"class_list":["post-19523","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog","tag-beijing-winter-olympics-cheetah-camera","tag-cheetah-camera","tag-olympics-cheetah-camera"],"_links":{"self":[{"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/posts\/19523","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/comments?post=19523"}],"version-history":[{"count":0,"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/posts\/19523\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/media\/19524"}],"wp:attachment":[{"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/media?parent=19523"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/categories?post=19523"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/tags?post=19523"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
