Abstract: Disclosed is a method and apparatus for extracting rules-based events from a soccer match video. The method of extracting a rules-based event from a soccer match video includes setting rules for each category of events to be extracted from a sports match video; extracting ball possession and ball coordinates based on tracking coordinate data of at least one player and tracking coordinate data of a ball in the sports match video, identifying that an event of a specific category is started at a specific point in time of the sports match video when a condition for before a start of an event and a condition for after a start of an event in the rule are satisfied, and identifying that the event is ended at another specific point in time of the sports match video when a condition for an end of an event in the rule is satisfied.
