eh.. sorry to ask, izzit champion league quater final onwards only got the total distance thingy? coz today only my 1st time saw it. wonder how they do it.... every player now got a chip in their shoe? izzit latest technology or what? any link for the news regartding this? I searched google and wiki but nothing comes out.

With the sort of money that the TV stations make, I'm sure they can afford to hire some part-timers to track each player. After all, they already have all the statisticians to calculate the number of passes, assists, goals, etc..

I think in CL they got one camera focusing at one player i mean each player, there are a camera focus at em all the time.. so i guess the just... guess...

haha

Ya, how do they do it? GPS?

I think is use cameras to focus on each players..They almost tracked 12km per game!

How to estimate distance from camera footage?

easy..they know how long the field is..so the field mayb divided into parts..then they can know the distance lo..haha..this is without high tech gadgets la..Maybe they have super camera than automatically calculate their distance traveled..

the field grass is splitted into 2 shades, if they know that gap then they can estimate

maybe new camera fitted with range finder..

Wouldn't it be easier to use radio trackers or something?

tracking a position u need atleast 2 camera focusing on a point. and then use the Pythagorean theorem to find. I dun think they use such a lame method. Grassy different color could be another method, but different field(like chelsea field, man utd field) they got different pattern(but what if they are running vertically instead of crossing the field horizontally?). it should have some syncronizing method out there....

it is true .. during last night chelsea match .. when david villa was subed out .. thers a box below the screen show "distance 10325M" or some thing like that .. so i think it's around 10KM villa has cover in the match .. w00t some really serious mathametics algorithm most been involved ..

I dono what's the purpose of calculating the distance...??
juz to show that they're hardworking player?? or ...

Can anyone tell me ??

just to show how hardworking they are

Oh?
Then if there is a vote poll ..i definitely will go for ROY KEANE lo..

its just another stat
those who really look into them as in analyzers, perhaps can make use of it to perhaps gauge how industrious the player is may suggest for the club to get that player

Just shows you how high tech the football world is nowadays

this is nothing when compared to the statistics in american sports. it's crrazy wan la, their stats

A combination of hardware ( bank of networked video cameras installed in major stadiums and ice hockey arenas) and highly touted image recognition and video processing software not only to compute players' stats including distance covered but a slew of features (there is no end to options) such as players and club team performance benchmarking. Included in this also database of visiting teams performances strengths and weaknesses. Just imagine Arsenal deploy this in their runup to S-finals meet with MU and EPL match of the season.


Twenty five or more years ago we had in theory image and video processing techniques and algorithms but not able to implement them for lack of powerful processors.

Yes today however the advent and proliferation of powerful desktop 'supercomputers' (Pentium 4 min and high end video graphic processor cards) that lend itself even to arming 'Big Brother' watching and tracking us.

No. they are not using radio tracking devices (so no GPS) on the players as it is disallowed. However radar tracking is curently under trials.

wtf..who revived a dead thread?
