1樓：
靠高速攝影機做影象處理，最終得到結果，過程肯定很複雜，全是影象處理的內容了，裁判只需要收到進球還是不進球的最終結果就行。也就是說，這個技術，不用在球和球場上安裝什麼特殊感測器，當然所使用的攝影機和給我們拍攝直播的攝影機肯定不同了。
至於如何將結果傳送到裁判的手錶上，太簡單了，不是重點，我都會做。

Goal-line technology in the spotlight at Maracana
GoalControl-4D
About GoalControl-4D
The system GoalControl-4D is the premium goal line technology on the
market that works with all balls, all goal frames, all goal net types
and -colors.
It is the result of restless development and countless hours of
testing the systems accurate ball detection and tracking function under
all weather conditions. Tests that included all football types,
different pitch grounds, various types of goal nets and game situations.
How it works
The GoalControl-4D system works with 14 high-speed cameras (7 per
goal) around the pitch at the stadium roof/catwalk. The cameras are
connected to a powerful image processing computer system which tracks
the movement of all objects on the pitch and filters out the players,
referees and all disturbing objects. The remaining object is the ball
and the system knows its three dimensional x-, y- and z-position with a
precision of a few millimeters in the coordinate system of the pitch.
When the ball passes the goal line, the system sends a vibration- and
optical signal to the officials watches. Of course, all camera images
of such goal event, and also of all near-goal events, are stored and can
be replayed anytime.
Technical data
7 cameras per goal
up to 500 frames per second
Accuracy of goal detection: up to 5 mm

Facerig的面部識別技術是如何做到的？對用眼球控制滑鼠的技術有什麼啟發？
小奈田 沒什麼啟發，facerig依賴ULSEE的面部實時識別的技術，現在手機上一堆軟體都在玩這個。在方向上和你要的眼動控制不太一樣。想要對眼球追蹤，現在Tobii在研究這個，面向電腦遊戲的商用版產品已經有了。16年的殺出重圍 幕府敢死隊都加入了Tobii眼動儀的支援。娛樂有餘，但遺憾的是精度不佳。...
Git commits歷史是如何做到如此清爽的？
汪志成 Angular開發組有乙個很明確的commit規範，包括英語語法要求之類的都給你講清楚了，不想研究的話直接follow就行了。至於時間線方面，rebase已經是常規的開發習慣了，只是有些場合有坑，坑不多，自己用用，避開就是了。 程墨Morgan 要求功能分支進入master branch必須...
鴻蒙是如何做到相容太極的？
羅理聖律師 華為的研發能力和科技大家都有目共睹。如果真的套安卓的殼，我也認為套得好啊，但願青出於藍勝於藍！在法律的框架內盡可能吸收 借鑑所有有益的東西，來強大自己，武裝自己，完善自己，有什麼問題？洋為中用，古為今用都是可取的。商場如戰場，盡可能降低研發成本，做出有價值的東西才是應有之義。中國研發出的...
