Character interaction behavior identification method in restaurant scene and safety monitoring system

The invention discloses a figure interaction behavior recognition method and a safety monitoring system in a restaurant scene, and belongs to the technical field of video analysis, and the method comprises the steps: determining the pictures of each video monitoring collection region, and carrying out the data preprocessing, and other tasks; establishing a restaurant employee face and human body target, customer human body and restaurant common article label library; the method comprises the following steps: establishing a label library of limb-related action behaviors interacted with common articles in a restaurant and interaction between people, judging the safety/non-safety of the behaviors and establishing labels; constructing a double-task double-flow parallel learning network, and extracting feature information of target recognition and feature information of character interaction action behaviors; according to the method, feature information extracted by a fusion model network is processed, a network m
