Abstract: Modern football intelligent monitoring technology utilizes computer vision and data analysis methods to monitor and analyze events and data on the field, aiming to optimize team tactics, integrate training plans, and evaluate players' performance. Compared to other monitoring technologies, intelligent monitoring technology minimizes interference with players' technical actions, exhibiting a greater adaptability to the environment. In fine-grained recognition tasks of individual events such as ball control and passing, intelligent monitoring technology demonstrates superior performances; while in global tactical analysis and player performance evaluation, it showcases a precise data mining and intuitive visual analysis. Furthermore, the referee assistance module within football intelligent monitoring technology contributes to establishing a more objective and accurate refereeing mechanism, ensuring fairness in competition, enhancing the viewing experience of football matches, and fostering improvements in refereeing standards.
