A Method for Detecting Football Player Actions Using IMUs attached on Shin Guards

In football matches, players perform various actions such as running, walking, passing, trapping, and shooting. Analyzing these actions is crucial for players to assess their performance and strategize effectively. Currently, the standard method for analyzing these actions involves setting up multiple cameras in the stadium to record the match and then analyzing the video footage obtained. However, this method is costly and is mainly accessible to professional teams with significant financial resources. It is used in specific environments such as training facilities and stadiums. There is a need for a system that can be easily used by amateur football players. This study proposes a method for analyzing the actions of football players using IMUs (Inertial Measurement Units) attached to both legs. The evaluation of the proposed method revealed that it was feasible to detect three actions - passes with the right foot, passes with the left foot, and shots with the dominant foot with an average F-score of 0.884 for three subjects.
