Patent ID: 11482031

Abstract:
The invention refers to the field of processing and analyzing video data received from video surveillance cameras, and more specifically, to technologies aimed at detecting a human in a frame and at analyzing their posture for subsequent detection of potentially dangerous situations by video data. The system for detecting potentially dangerous situations contains video cameras, a memory, a graphical user interface (GUI), and a data processing device. Data processing device is configured to receive real-time video data, analyze the received video data, obtain horizontal lines for each of the set corrective vertical lines, split the frame into zones, construct the leg vector based on a pair of the lower limbs key points and determine their belonging to one of the resulting zones, construct a back vector, determine the lower limbs tilt angle between the resulting back vector and the leg vector, determine the human's posture, and detect a potentially dangerous situation, if the human's posture is one of the postures indicating a potentially dangerous situation.
