All 1,248 players across the 48 teams at the 2026 FIFA World Cup were scanned before the tournament so that FIFA could create an exact 3D avatar for each one. The competition was followed across television, live-score services, betting markets and mobile products. Because an offside call can cancel a goal or stop an attacking sequence, confirmed decisions also affect the live match state used by betting markets, where football odds on bizbet can change once the official outcome is known.
Inside the officiating system, however, the avatars had a precise job: they supplied individual body measurements for marginal offside assessments and made the resulting 3D replays resemble the players involved. The upgrade built on semi-automated offside technology first used at the 2022 World Cup, while changing how quickly clear positional decisions could reach officials on the field.
Before the tournament, each player stood inside a scanning rig equipped with 36 cameras. A one-second capture recorded body shape and dimensions, and an AI-assisted process converted those images into a digital avatar. FIFA used the models only within its advanced semi-automated offside workflow and the related broadcast visualisations. The purpose was not to let an algorithm judge a player's intent or interpret the Laws of the Game. It was to improve the geometric model used when a decision depended on a shoulder, knee, foot or another playable body part being marginally ahead.
The system fused two streams of information. An optical camera array tracked up to 29 points on each player's body at 50 frames per second, while the connected match ball transmitted movement data at 500 measurements per second. The faster ball signal helped identify the kick point: the instant a teammate played the pass. Player coordinates from that same moment were then used to calculate whether an attacker was in an offside position. Machine-learning models supported the tracking and reconstruction, but the output remained a recommendation within an officiating process rather than an independent final ruling.
At the 2022 World Cup, the technology generated an alert for the video assistant referee team, which checked the proposed kick point and offside line before communicating with the on-field officials. The advanced 2026 workflow added a faster route for clear positional offsides. In those situations, the system could send an automated audio alert directly to the assistant referee, reducing the relay time through the video operations room. The assistant still made the on-field signal; the technology supplied the positional information sooner.
Faster confirmation also matters to services following the match in real time. Live betting depends on an up-to-date official score and match state, so a marginal offside that determines whether a goal stands can leave odds temporarily reacting to an unresolved event. Quicker communication reduces that interval once the referee team confirms the decision.
| Process step | 2022 World Cup | 2026 World Cup |
|---|---|---|
| Clear positional case | Alert checked in the VAR room | Audio alert can go directly to the assistant referee |
| Complex or judgement-based case | Human video review | Human video review remains necessary |
| Player representation | Tracked skeletal points | Tracked points combined with individual 3D avatars |
Offside is not always a purely positional question. Officials may still need to decide whether a player interfered with an opponent, attempted to play the ball or gained an advantage after a rebound. Tracking quality can also be affected when bodies overlap, a player is partly hidden from a camera or the relevant touch is difficult to isolate. Those cases remain with the video match officials and the referee. The distinction matters: AI can measure position and propose a line, but it does not replace every judgement required by the law.
Once a decision is confirmed, the same tracking points are used to generate the 3D animation shown in the stadium and supplied to broadcasters. On mobile, that replay may sit beside score alerts, clips and betting features, while a separate bizbet ะฐะฟะฟ ัะฐัะฐั link handles app installation rather than any part of the officiating feed. The 2026 avatars made the replay more recognisable because the visualisation used the scanned appearance and proportions of the actual players instead of a generic figure. This public-facing step does not make the underlying calculation infallible, but it gives viewers a clearer picture of the body point and kick moment used in the ruling.
A system operating at tournament scale depends on more than a single AI model. Computer vision identifies and tracks players, sensor fusion aligns optical data with the connected ball, and low-latency processing turns both streams into a recommendation quickly enough for a live match. Model validation is equally important because performance must be tested against crowded penalty areas, unusual body positions and temporary occlusion. Engineers also need clear audit trails so officials can inspect the kick point, tracked body part and generated line rather than receiving an unexplained answer.
The central change was not that AI suddenly began making every offside decision. FIFA combined more precise player modelling with a faster communication route for clear positional cases, while retaining human review for situations that required interpretation. That division of work is the most useful way to understand the 2026 system: machines supplied rapid measurement and reconstruction, and officials remained responsible for the decisions that could not be reduced to coordinates alone.
