Photo finish

From Wikipedia, the free encyclopedia

A photo finish occurs in a sport racing, when two (or more) competitors cross the finishing line at near the same time. 在体育赛中当二个或多个赛手几乎同时通过终点线时，这时有用一个“终点摄像” As the naked eye may not be able to discriminate between which of the competitors crossed the line first, a strip photo, a series of rapidly triggered photographs or a video taken at the finish line may be used for a more accurate check. 当肉眼不能辨别哪位赛手先过线。一个“条形摄像”一系列的快速触发摄像 或是在终点线上有个电视摄像用作更精确地检查。 Nowadays, the photographs may be digital but usually involve special equipment.现代，摄像器可以是数码的，总是包括了特别的设备 They may be triggered by a laser or photovoltaic means.它们可能是激光触发或者是光电触发。 Historically, a hand cranked strip photograph was taken at the finishing line.历史上有一个手动曲柄触发的摄像器在终点线上 Today, finish line photos are still used in nearly every modern racing sport.今天，终点线摄像器仍旧使用在接近最现代的体育比赛中 Although some sports use electronic equipment to track the racers during a race, a photo is considered the most important evidence in selecting the winner. Finish photos are used in nearly all professional human and animal races, except for races in which athletes are divided into lanes that use touch pads, such as competitive athletes.. 虽然有些体育中用了电子设备去跟踪赛者，在比赛中，选择名次时，摄像被认为是最重要的设备终点摄像几乎被用于所有的职业选手和兽类比赛特别是有时运动员要进入小路，它们就用接触贴片。如游泳比赛， However, they may be examined only when a race is close or when a record has been broken.他们可能仅仅是用于接近该项记录或破记录的时候，进行测定的。
