Specific type personnel identification method based on human skeleton key point detection

The invention relates to a specific type person identification method based on human skeleton key point detection. The method comprises the following steps: acquiring a monitoring video clip of a position where a specific type person is easy to appear; face detection, pedestrian detection, pedestrian tracking and human body skeleton key point detection are carried out on a single-frame image in the monitoring video clip; associating a corresponding face and a pedestrian based on a position relationship between a face frame of face detection and a pedestrian frame of pedestrian detection; judging whether the pedestrian performs the landmark action or not according to a human skeleton key point detection result of the pedestrian; when the time when the pedestrian appears in the monitoring video clip exceeds a set threshold value, or the number of times when the pedestrian performs symbolic actions in the monitoring video clip exceeds a set threshold value, judging that the pedestrian is a suspected person of a
