Taking identification method and system and storage medium thereof

The invention relates to the technical field of safety early warning, in particular to a fight recognition method and system and a storage medium, and the method comprises the steps: detecting pedestrians in a monitoring video through a target detection model; checking whether two or more pedestrians exist in the monitoring video or not, and judging whether detection frames of the pedestrians are intersected or not; and taking an intersection of the intersected pedestrian detection frames, and calculating a minimum outer surrounding rectangle of the intersection as a self-adaptive target area. And taking the target area as an input, sending the input to a recognition model, and recognizing whether the behavior is a fighting behavior or not. According to the fighting recognition method provided by the invention, the pedestrian interaction area in the monitoring picture is adaptively extracted through a prior technology to replace the whole monitoring picture, so that the input resolution is greatly reduced, th
