Zusammenfassung:The invention provides a laboratory safety management oriented personnel behavior monitoring method. According to the invention, based on a laboratory monitoring video, a face recognition result and human body position information in a video frame are calculated at the same time; transmitting the face recognition result to the human body based on the geometrical relationship between the face recognition result rectangular frame and the human body position information rectangular frame; the foot center position of the human body in each frame of the video is recorded, and the movement track of the human body in the video is extracted; a plurality of key points are calibrated in a laboratory plane graph, positions corresponding to the key points of the plane graph are searched in a video sequence, the same marks are made, a two-dimensional mapping relation between a monitoring picture and the laboratory plane graph is established, and the motion trail of the human body in the video is mapped into the laboratory
