[問題] 鷹眼電子系統的技術

[peal (新年快樂)]

請問大家

有沒有人知道 鷹眼的原理是什麼?

感覺很方便吶...

在球場正上方照?

鏡頭怎麼跟球呀....

找到了
自問自答

The system is based on British missile-guidance system developed by
31-year old computer scientist and mathematician Mr. Hawkins. He first
invented the Hawk-Eye to follow the ball in cricket matches. The tennis
version was developed in 2002.

The Hawk-Eye system consists of eight high-resolution digital video
cameras situated around the tennis court in strategic locations. They
run 60 frames per second, follow the exchange and feed the data about
the flying ball to the computers in the control room. A rally produces
about a billion calculations which determine the trajectory of the ball
hit by the players. The combination of information from the eight cameras
calculates the three-dimensional trajectory of the ball and derives the
exact place
where the ball is going to bounce on the ground. The precision is now
within 1cm but it will soon be measured in millimeters. After that the
data are transposed on the graphical display of the tennis courts with
lines and broadcasted on TV.

推 Xconqueror:方便歸方便...但永遠不能取代"人"的地位...
推 colan8:能不能取代人  這很難說  不過比賽是以人為主 短時間內
→ colan8:取代不了而已  如果網球球員組成了工會就難說了
→ steveccc:會不會以後 排球 羽毛球..... 也都引進鷹眼技術阿?
推 beyvaisu:precision是一公分 可是之前roddick跟對手連用五次成功
→ beyvaisu:那場有幾球只離線或壓線幾公厘而已XD
推 showyi:雖然是一公分 也比人眼好 之前不是還有線審界內判界外的
推 Brian23:感覺像Mo-cap系統~
推 evenchou:我覺得現在這種措施很不錯 挑戰權的制度
