To meet the demand, it is necessary to go beyond mere data collection and transform it into meaningful information that helps athletes improve their performance. Combining AI technology with domain knowledge from the field of sports science is key to the future development of AI in sports. Sports events or training usually involve the analysis of multiple sensor signals, including the aforementioned sensor-based and video-based technologies. During the 2022 FIFA World Cup, several high-tech tools were used to assist referees and ensure the smooth running of the event. Controversial situations were identified by AI, providing referees with clearer and more reliable decision-making bases, and ensuring that all players, coaches, and fans were satisfied with the results. This integration of sensor and imaging technologies, analyzed by AI for precise judgments, is an excellent example of the sensor fusion of sports technology.
