Title:
HUMAN-MACHINE INTERACTION BEHAVIOR SECURITY MONITORING AND FOREWARNING METHOD FOR UNDERGROUND BELT TRANSPORTATION-RELATED PERSONNEL
Document Type and Number:
WIPO Patent Application WO/2020/253308
Kind Code:
A1
Abstract:
A human-machine interaction behavior security monitoring and forewarning method for underground belt transportation-related personnel, comprising positioning a location of a belt in a video on the basis of a camera calibration principle, and performing three-dimensional ROI delimiting on the basis of the location and size of the belt; performing detection before clustering multi-person keypoint detection on belt transportation-related personnel using a "bottom to up" keypoint extraction method to improve detection efficiency while ensuring detection precision; and respectively projecting human body keypoints and an ROI for two times, estimating a positional relation between a human body and a belt on the two projection planes, and screening out and forewarning an unsecure behavior during human-machine interaction to eliminate a severe security risk caused to a belt transportation system by an abnormal contact between personnel and a belt area.
