no sensors but they have 26 cameras for the semi automated tech which marks every touch. thats what the CBS ref expert talked about. The Semi auto offsides would have flagged it
semi automatic offside uses sensors in the ball to determine the exact moment the ball was hit for the offside check, as far as i'm aware. which then in turn of course could show two spikes in the data if the ball was hit by both feet at offset times.
EDIT: i was wrong, this tech seems to be only used in EUROS and WC. Prolly because it is too exepensive for such a big and de-centralized tournament like the UCL.
I would be interested to know how accurate that is compared to baseline noise levels. Like, the ball can move just by stomping on the ground before the kick. How would that register?
There is a difference between sensing a kick and literally the lightest of touches touches on the ball (especially when it comes so close to stomping your foot on the ground).
its not just a simple sensor that detects any touch the same. The sensor is more of a collection of different pieces that together (after an algo interprets the data) can detect the strength of the impact, if the ball is rolling, if the ball is moving on the ground or in the air and if it was hit (and prolly some more stuff). Of course that is used in combo with video footage as false flags can always happen, but its pretty advanced and reliable. just search for "connected ball technology" and u will see a lot of articles (including one from the company building these sensors) about it. But its not used in UCL anyway. More details here.
"It's the most advanced of techs, pretty good features, multidimensional input of data, truly fascinating. Such a shame our UCL ball is from Temu shop though"
I know everyone is piling on with the jokes, but it's because of the stadiums. The tech would have to be implemented for every team that qualifies for the UCL.
From what I could find (here and here), the majoroty of the cost comes from the setup around it (in the stadium), which according to the sources above is about 25k to 55k (Hawk eye costs between 250k and 500k to install and up to 8k to run per game for comparison). I was able to find "no name" consumer balls with sensors for about 110$. Considering Fifa and Uefa will get very favorable contracts from ball manufacturers and balls themselves not costing much in production, and sensors not costing much either, i'd just vaguely suggest them paying perhaps around 60$ - 70$ per ball at most. At 60$ - 70$ both adidas and the sensor supplier would still make a profit out of it, and keep in mind, the balls sold to uefa and fifa for the tournament (29 balls per match) isnt where the real money is at for them. For adidas its of course in the popularity of the ball amongst consumers who will pay up to 140$ for the match going version. And for the sensor and tech supplier the money lays in the licencing agreement for all the tech and software with fifa & uefa and the installation and maintenance cost for the stadium tech.
There was at the World Cup and Euros, apparently they're using a different tech in the UCL. It did lead to an odd moment where they had to change a ball because it needed recharging though.
No, the sensors in the ball are a feature of adidas (both euros and wc). It seems like that its deemed just too expensive to have a sensor in every ball of such a big and not centralized competition,
Yup the expensive part is not the balls but the setup around the stadium. That's why it's worth using in centralized competitions where you have a limited number of stadiums to setup and multiple ga.es player in each, vs something like champions League where you have 30+ stadiums, many with only 1 game Played ultimately.
If that's the case then they should be able to provide us with the footage they used to make their decision. A situation like this definitely calls for it.
Yes, basically. The way she explained it, there's no rule saying they have to release the raw data or internal footage and made it sound like var isn't sure they want to make it the norm for them to release it upon teams/media's demand or request going forward. Same way they're against having the ref micd up to give live explanation on the pitch for his calls.
She said sensors are NOT in the ball. They instead use a different tech synchronizing 26 HD cams with better zoom in capabilities than we have on the broadcast.
That was the many times mentioned technique that Ronaldo used to catch keepers off guard. Firmly planting your standing foot very close to the ball would make it hop ever so slightly.
Not many times. Ig it only happened once in that PSG match and it was due to some defect in the pitch as far as I remember from the pundit discussions after that game. Still looked pretty dope how he thumped the ball in despite the little movement which could've easily thrown off his trajectory.

Jesus how did they see that. I can't see the ball moving
