How the World Cup’s AI instant replay works

Рік тому

A new hyper-accurate technology, and referees' eternal quest for objectivity.

The offside rule, which requires attacking players to be behind either the ball or the last defender, is a rule that sounds objective, but has led to a lot of questionable calls, partly because it can only be judged from an individual perspective. Until now. Meet the new “semi-automated AI offsides technology” at the 2022 World Cup.
This technology relies on a sensor in the ball that relays its position on the field 500 times a second, and 12 motion tracking cameras mounted underneath the roof of the stadium that use machine learning to track 29 points in players’ bodies. In other words, FIFA is mo-capping players, just without the funny gray suits. And the whole system will alert referees when a player is offside. If you’ve been watching the World Cup, you may have also seen the motion tracking information being used to create an immediate 3D replay.
This system seems like it could be capable of eliminating “bad” offside calls, or maybe bad calls altogether - but its new precision will inevitably impact gameplay no matter what. And the first World Cup to feature it will show us exactly how.

There’s nothing artificial intelligence about this technology. Really wish everyone would stop throwing that phrase around.

The artificial intelligence is the part where it is able to have a 3D view of the entire pitch.

@AlessandroLosi Рік тому

@Zaydan Alfariz the issue is that they didn't specified which type of "camera" it's being use. For example, if all they are using is laser scanning, there is no image recognition at play, but just a 3D reconstruction from laser data. Also because image recognition could have some slight errors, and due to the precision required for the VAR, i hope they are not using that.

@randomguy2108 Рік тому

i think they use AI to generate the player's position in 3D from the multiple camera angles

@pedroaugusto656 Рік тому

As far as can tell only the ball have sensors, the players don't. So in order for the camera to track players it has to know the difference between a dog running in the field and an actual human being. So somewhere there's a computer vision machine learning model capable of knowing how a human being running in football field looks like. That's intelligence.

There is still a problem with the semi-automated VAR, tho. In the Saudi Arabia-Argentina game, Lautaro Martínez scored a goal that was ruled out because he was supposedly offside, but after the match people noticed that the semi-automated VAR was putting him offside because it was taking into consideration the center back that was just beside him, and it was not considering the Saudi left back that was putting him in the onside zone. Mistakes likes this MUST not happen, specially in a World Cup.

Off side rule being automated is an example of imposing a rule over it's original objective, in this case, off side rule intention is to prevent an unfair advantage of the attacker over the defending team. Having the tip of a finger from a hand or a milimiter of hair passing over the strict line of the defender does ot imply an advantage for the attacker and might be due to just a natural body movement, that might be the main reason for fans to hate the AI VAR system, maybe changing rules to prevent the attacker from having his point of support/supportig leg and torso over the line (or something similar) might be a more suitable parameter while still being just as objective

@samuelzapote Рік тому

Your fingers don’t count, they can’t be used to score a goal. And hair strands are not taken into consideration cause the cameras can’t see them individually. But you’re right, the tips of the knees or shoulder tips shouldn’t be counter offside to the last mm. I think they should count it offside if more than half of their body passes the offside line.

I really dont like the idea that its already objective, not yet. I think the technology should improved in order to not depend on the referee's decision and it still does although the scene rendering is completely automated. I think it should (and will) evolve to somethig like Tennis or Volley in which the computer says directly whether its offside or not, and I don't think anybody would complain about a mistake anymore and if a mistake were to happen, it would be completely random, the criteria would be the same for everyone. Like a pact: the computer said, than it is what it is. Things in soccer would be muuuuch easier that way.

The technology is a good advancement for the sport like I think literally all the other sports have it like volleyball, basketball, rugby, etc, what I think needs to happen now is a readjust of some of the rules. The offside rule was created with the intention of preventing one team to "leave" a player close to the opposite goal giving him and advantage 1v1 for easy goals; but it got to the point that some teams will be trying to intentionally create offsides there's practically no advantage to having one knee a few cm infront of the last player or having a hand or shoulder creating an offside; they should change the rule so that if you're side by side or maybe you can be up to 30cm behind the last player and it's not offside, that would make no more teams trying to actually force offsides and playing defense Edit: you actually don't need the 30cm probably the best would be that "the player is offside if they're completely behind the last defensive player when the pass was made"

Man, this whole World Cup is just reminding me how much I don’t like the current offsides rule. Why do the inches or centimeters matter? If a good ball is coming over the top or through, that player is getting to goal regardless of even a half a meter. How is a player supposed to measure centimeters in real time? How is a lean more advantageous for the attacker? For the health of the game, I really think they should simplify the rule and make it easier to call such that refs can easily make the call without an entire computer program having clarify and dragging back goals and killing momentum and morale. At lower levels, do we just suffice with the eye-test offsides until we get counted off by a shoulder or knee by technology at the highest level? Then again, refs always just give the benefit of the doubt to the defenders, so you really shouldn’t be close at all to be safe. So, in my opinion, they should either revert the offsides rule back to when you had to be clearly behind the defender. Or (what I’d prefer), you have the Arsene Wenger rule where you just need one body part being in line with the last defender. This actually really wouldn’t be that hard to recognize because most players making runs are watching the defender as a reference point and they would be timing their runs accordingly either way. Just my thoughts.

There is some threshold for where someone is and isn't offside. No matter how you choose to define the rule, there will be one spot where a player could be and you would need to nitpick their exact position to make the call. By making the rule more lenient, you're just moving the threshold. By being less strict, you are just being inconsistent on your ruling. I understand an argument about the use of tools like this being bad because it slows the game down (I disagree with this point if view, but I think it's an acceptable one.) But I don't think an argument of "eh, let's just be worse at judging this rule because I don't care about it" is reasonable.

@robertorama8284 Рік тому

@@MattMcConaha There's no threshold in the rule, not sure what you're talking about. The rule has 800 words explaining some situations where the interpretation of the offside is completely subjective (which makes it worse, e.g. the last goal in France vs. Tunisia). If that's what you're making a reference with threshold, well, it's not it. I'm aware how limits work, the main point of my argument around the threshold is to make it visible for the human eye and for the players to be able to avoid an accidental offside. You can enforce a strict threshold and measure it against that (since the technology has the precision to do it), you will still have nitpick situations, but at least it will happen less often, and when you have an offside it would be clearly visible.

As long as you pick a rule and stick with it, then the rule is the rule. Something like a simple "whose foot is farther ahead" will achieve the same general guideline of "don't be ahead of the last defender" but with less confusion over the details.

@KaladinAndSyl Рік тому

The problem with VAR is that it isn’t consistent. It needs to be used on all debatable incidents or not at all. And calling the referee only if there is a “clear and obvious error” is not acceptable, as that leaves the decisions to humans whether it is a clear and obvious error, which defeats the purpose. A slight handball in an El Clásico shouldn’t be treated differently than a slight handball in Leeds v Crystal Palace. And the anonymity of the process is problematic, because right now I’m 80% sure that they roll a dice before making decisions.

@Pinkybum Рік тому

You did not explain the offside rule correctly. 1. Yes 2 defensive players do have to be between the attacking player and the goal but, importantly, when the ball is played to them, i.e. at the moment the passer touches the ball. 2. The attacking player has to be active, i.e. they need to be affecting the play at the moment the ball is passed to them. The second point confuses people a lot because you get offsides not called even though an attacking player doesn't have 2 defensive players between them and the goal when they are not actively involved in the play. Also, players can be offside if they are obstructing the goalkeeper even if they didn't touch the ball because they were affecting play.

One of the things which rarely, if ever, gets talked about is how they determine which frame to stop the footage on before you can even begin to compare the relative position of two players. Do they use high speed cameras for that? If not, the resulting information can be skewed massively in the 1/30 or 1/60th of a second each regular TV camera can record the moment the ball leaves the player's foot for the potentially offside pass. Often, jumping one frame forward or backwards it all it takes to be clearly offside or not.

@pasta5818 Рік тому

They do use high speed cameras to match the exact frame the ball was kicked, thats the key moment to then determine when the pass was made what the position of the receiver

The use of high-speed cameras is the reason you get flawless slow-motion footage during games so I think most of the cameras are able to do that.

I think there’s a mistake around the 3-minute mark - in VAR decisions in the English Premier League, offside is already decided by “AI”. The referee more reviews instant replays of fouls and handballs, but offside is an objective decision based on technology stuff lol

@syverolesen7664 Рік тому

It's not decided by AI. the VAR refs can use technology as you say, but they have to manually create the lines. Which is why offside decision can take minutes, leading to frustrating break in play. Especially when reviewing multiple things at once, for instance first reviewing if a foul should be a pen, and then whether that pen should be voided because of an offside decision earlier in the play. In this years World Cup it's much more automated and the offsides are decided in seconds, not minutes.

@etidancal Рік тому

There is no advantage when a knee or a shoulder is a bit further. That could also be the players physiognomy. They have to really think about when it is advantageous for the team who did an offside. Back in the day was the line of the player’s feet. If the defense is not fast enough to go to the ball that’s not the forward’s fault.

@fep_ptcp883 Рік тому

The REAL problem imho is that this stuff should work as a challenge, like in volleyball or tennis. The team desires to modify the referee's call? Challenge it. If it was a good call, the team cannot complain anymore until half-time. Reviewing every single thing is a pain in the _ss, the game should flow and only the evident mistakes (noticed by the defending team) should be called out and modified. The player knows if he didn't commit a penalty, so alert the captain to ask for a review. This should push the players to act in a more fair manner, no point letting your team argue a penalty you DID commit. The current situation takes back lots of goals in milimeter-offside plays. Let the team judge if it is worthy reviewing the play. Or let the offside be automatic, but introduce the challenge for penalty/no penalty and red card/no red card

Free kicks are a powerful tool in football, so having a foul in favour on you can be a game changer. That also applies to yellow and red cards, if the other player have a yellow card it will play more carefully and you have more chances to pass them. Red cards leaves the other team with -1 player the whole game and that's an advantage that can make the game turn into your favour

@MattMcConaha Рік тому

Tracking a ball is a piece of cake compared to tracking a human. For a number of reasons. For instance, to track a tennis ball you might just know what color the ball is. It's that weird yellow-green. And you know it's a sphere. You place your cameras around the stadium, calibrate their pose relative to the court, and then you can process the video using fairly basic algorithms to find Circular objects that appear in frame which are the correct color and appear in the same ray-traced position on all cameras. And in a lot of sports they even mount a location sensor in the ball, which by itself could even be enough. For a human you can rely on their color, their shape, or pretty much anything else to write a basic algorithm to locate them like that reliably, especially when there are a bunch if them out there on the field.

On top of that a lot of refs aren't going to review footage for penalties when we should be reviewing it everytime. Players will throw themselves down in hopes of a penalty and sometimes it's just given 🤷🏽‍♂️ we have the technology but the refs are so inconsistent with whether or not they use it and when they do use it it's kind of just nitpicking at this point

@@renex_g3915 Because it implies the player with the ball in their example would not be allowed to run forward with the ball past the defenders. Now he does *very quickly* say "Or be behind where the ball is", implying the player cannot use any kind of lone (No team mates involved) manueve to get past the last defenders that results in him being closer to the goal than the ball, which is not true. It also doesn't differentiate between the offside position and the offside offence. If in their example, the player with the ball were to shoot and score, whilst his team mate was in the offside position, their implication is it wouldn't count because the team mate was in that offside position. But that team mate would only commit an offside offense, if they became involved in play. For example, if the player with the ball took a shot, it rebounded off the goal post and the team mate in the offside position then got the ball, that would be an offense. Or if the player with the ball passed the ball, past the 2nd to last defender, to his team mate who successfully receives the pass, that is an offside offense.

Being offside means you're behind the defense. So if when the ball was passed to you, you're already behind the enemy's defense, thats just not fair because they wouldnt have a chance at stopping you. Thats a clear advantage of being offside. But what this does is take away the advantage part which was the main point of the entire rule. If a finger was past the last defender, you're offside. Whether you had an advantage with that finger or not.

I think offside should be determined by a players center of mass, not whether their hand is over the line by inches. I've seen PL goals disallowed where a player was called offsides because they were raising their hand calling for the ball. There's no real advantage there. That said, if someone is leaning toward into the first step of a sprint, I do think that is a real advantage and should be called off. Admittedly center of mass is difficult to measure especially with cameras, but the tech here seems that it would be more than capable of producing very good estimates. But yeah, I think it's an essential but annoying rule that let's the defense off the hook more than it should.
