These artifacts, makes the Rio Olympics final score accuracy-about the Olympics, athletes, camera-IT information

Shang Saturday, 2016 years in about Olympic official opened curtain, in Qian two a game Japan, veteran Terri fourth times station in Olympic shooting range, she three times near eliminated three times played 10.8 ring of near perfect of results, eventually get Silver; Sun 400 meters freestyle created personal near two years best results, regrets harvest silver Hou eye tearful water; Zhang Mengxue more war more Yong, won China delegation first gold.

Regret, desire, excitement, and athletes have surpassed themselves, and behind this, Olympic's own technology is also in progress.

Track: finish line camera photo shooting 10,000 frames per second

▲ Photo finish camera

In this year's Rio Olympics, set at the finish line photo finish camera can take 10,000 frames per second, can more accurately determine the ranking of athletes reach the finish line.

But you know in the first Olympics, also use a manual chronograph Pocket Watch, countdown timer limit is 30 minutes, players worked so hard to run a marathon, don't even have a score! Until the 1932 Los Angeles Olympics, artificial time end times only, Olympic Games entered the era of electronic timing, can be accurate to only 1% seconds; the 1972 Munich Olympic Games, strict German unit of measure is accurate to 1 per thousand seconds; to the 2004 Athens Olympic Games, just the end of the camera can shoot 1000 photos per second, completely eliminate the possibility of disputes.

When each of the runners cross the finish line, parts of the body of the camera will be the first to reach the finish line of the electrical signals sent to the timing, so as to record their game-time, to help referees determine the title of horseshoes.

Swimming: "double insurance" without controversy

Swim what? Ning Zetao ABS? Women's swimwear show? Or that record-breaking peak? Hey, if there are no modern technology, you see is probably controversial.

As early as 1960 Rome summer Olympics men's 100-meter freestyle. When first to second-place swimmer almost at the finish line, splashing water on the lane, sight difficult to ascertain exactly distinguish with the naked eye, there is a great deal of controversy. Electronic touchpad appears to solve this problem.

Starting from the 2012 London Olympics, and introduced a variety of new timing equipment very futuristic, including prompt indicates that the top three finish "led swimming rankings", track and field and water sports as well as for high-accuracy quantum-mechanical timer, the resolution has been upgraded to the one out of 10,000 seconds.

In addition, high-speed cameras at a rate of 100 per second capture the image and sends it to the control room of the timekeeper. These speed cameras in the swimming tournament only as a backup system in case of player contact with the touchpad fail or get too light.

Archery: by human eyes electronic eyes

Picture archery

Never look at the archery game felt very worried, if it is easy to judge, when pressure situations happen, there will be several referees ruled jointly, pending results and may even occur, but this year the Rio games, look to this.

Starting from the games, archery will use the "electronic target" instead of the referee the naked eye, improve the accuracy of the verdict. New wands of two scanners can identify gaps within 0.2mm of the human eye cannot perceive. Verdict a seconds display, players no longer have to anxiously wait for the results, you can concentrate on shooting the next arrow, but can also reduce the potential for miscalculation.


这些神器,让里约奥运会运动员最终成绩精确无误 - 里约奥运会,运动员,摄像机 - IT资讯

上周六,2016年里约奥运正式拉开帷幕,在前两个比赛日中,老将杜丽第四次站在奥运射击场,她三次濒临淘汰三次打出10.8环的近乎完美的成绩,最终获得银牌;孙杨400米自由泳创造个人近两年最好成绩,遗憾收获银牌后眼含泪水;张梦雪越战越勇,拿下中国代表团首金。

有遗憾、有渴望、有激动,运动员本身已经超越了自己,而在这背后,奥运自身的技术也在不断进步。

径赛:终点摄像机每秒可拍摄1万帧照片

在今年的里约奥运会上,在终点线设置有每秒可拍摄1万帧照片的终点摄像机,能更精确地判断运动员到达终点的名次。

可是你知道在最初的奥运赛场上,还用的是手动计时怀表,倒计时极限是30分钟,运动员辛辛苦苦跑个马拉松,连成绩都没有!直到1932年洛杉矶奥运会,人工计时时代才正式画上句号,奥运会开始进入全自动电子计时时代,可也只能精确到百分之一秒;1972年慕尼黑奥运会,严谨的德国人把计算单位精确到了千分之一秒;到了2004年雅典奥运会,光是终点的摄像机就可以每秒拍摄1000张照片,完全杜绝了出现争议的可能。

当每名选手跑过终点线时,摄像机会将最先触及终点线的身体部位的电子信号发送给计时台,从而记下他们的比赛时间,帮助裁判确定可能差之毫厘的冠军归属。

游泳:“双保险”让成绩没有争议

游泳比赛看什么?宁泽涛的腹肌?女选手的泳衣秀?还是那打破纪录的巅峰时刻?嘿嘿,如果没有现代的科技的话,你看到的或许就是争议。

早在1960年罗马夏季奥运会上的男子100米自由泳比赛。当时由于第一、二名的游泳选手几乎同时到达终点,水花四溅的泳道上,肉眼视线难以确切判别先后,就出现了巨大的争议。而随后出现的电子触摸板解决了这一问题。

从2012年伦敦奥运会起,又引入了多款极富未来感的全新计时设备,其中就包括可迅速指示前三名完赛者的“游泳排名指示灯”,以及用于田径和水上运动的高精度量子计时器,其分辨率已提升至百万分之一秒。

此外,高速摄像机以每秒100幅的速度捕捉图像并将其发送给控制室内的计时员。这些高速摄像机在游泳赛事中仅作为后备系统,以防出现运动员与触摸板的接触失败或接触太轻的情况。

射箭:由人眼到电子眼

每次看射箭比赛都觉得很焦急,要是很容易判断还好,一旦有压线的情况发生,就会有好几个裁判共同裁定,甚至还可能出现待定的结果,可是今年的里约奥运会上,这种情况就看不到了。

从本届奥运会开始,射箭项目将采用“电子靶”代替裁判肉眼,提高了判决准确性。新箭靶的两个扫描装置能分辨出人眼不能感知的0.2mm以内的差距。判决结果一秒内即可显示,运动员们不用再焦急地等待结果公布,可以集中注意力射出下一箭,同时也可以减少误判的可能。
