Beschreibung
Zusammenfassung:	A safety monitoring and early-warning method for a man-machine interaction behavior of an underground conveyor belt operator is disclosed. The present invention determines a belt position in a video based on a camera calibration principle, and delineates a three-dimensional region of interest (ROI) based on the belt position and size. By using a "bottom-up" key-point extraction method, multi-person key-point detection of conveyor belt operators is performed by detection followed by clustering, thus guaranteeing the detection accuracy and improving the detection efficiency. The human body key-points and the ROI are separately projected twice, and a relationship between the human body and the belt position is estimated based on the two projections to screen out unsafe actions during man-machine interaction and give an early warning, so as to avoid a major safety hazard in the belt conveyor system caused by an abnormal contact of the operator with the belt region.
