The Technology Behind the Magic Yellow Line

CurtMonash writes "Fandome offers a fascinating video explaining how the first-down line on football broadcasts actually works. Evidently, theres a lot of processing both to calculate the exact location being photographed on the field — including optical sensors and two steps of encoding — and to draw a line in exactly the right place onscreen. For those who don't want to watch the whole video, highlights are here."

    are the ones on the platforms at train stations. (In QLD anyway) The closest thing we have to this in sports around here is either during swimming, or between balls during a test match, when the commentators are bored and start drawing lines all over my TV.

    You're thinking a bit too far ahead, I think. I say we just hack some Roombas with spraypaint cans and GPS and let them sort it all out.

    I thought Football was a game played with your feet! What the article discusses is a bastardised form of Rugby.

    Lessee. The football field is 360 by 160 feet. You need a resolution of at least 1 inch This is very coarse, really, but let's say it's 1 inch. This means your field is a giant 4320 by 1920 color screen right here. Which is, like, quad HDTV or something like that. You know what? Fuck the game, let's see some movies.
