Teaching scene intelligent analysis system and method based on group behaviors

The invention discloses a teaching scene intelligent analysis system and method based on group behaviors. The system comprises the following parts: M1: a multi-modal data acquisition module; m2: an individual behavior identification module used for converting the original multi-modal data related to the individual in the M1 into an individual behavior sequence; m3, a group behavior analysis module which is used for aggregating the individual behavior sequences of the students into a student group behavior matrix and analyzing individual behaviors from a group perspective; m4, a teaching scene judgment module used for carrying out teaching scene division and carrying out performance judgment on abnormal individuals; and M5, an education domain knowledge definition module which is used for forming teacher and student behavior classification coding specifications and teaching scene classification coding specifications. According to the intelligent teaching scene analysis system and method based on group behavior
