Since Lenovo became FIFA's first technology partner in October 2024, the "first AI World Cup" has been the core marketing theme for the 2026 FIFA World Cup in the United States, Canada and Mexico. This marks the first large-scale deployment of AI across multiple core systems, including TV broadcasting, referee decision-making, match analysis, and event operation, after nearly 20 months of preparation for the 39-day tournament. A key highlight is the "Referee View" footage, which now features more stable images and lower latency thanks to Lenovo's AI image stabilization algorithm. This algorithm optimizes high-speed footage from the referee's wearable camera in real time, reducing frame jitter by an average of 50% and a maximum of 70%. Li Bin, head of the Referee View AI Video Enhancement System, noted that referees often run more than 10,000 meters with sudden stops and turns, and the camera is limited to 17 grams, making hardware improvements unfeasible. The team integrated the two most common stabilization algorithms in the frequency domain and time domain. Compared with macro indicators such as 6.8 million on-site spectators and expected revenue of 15 billion US dollars, these technological innovations are key footnotes defining the tournament's historical coordinates and a rich legacy for subsequent events.
