Person detection and action recognition system for item removal
A recently granted patent (Publication Number: US11974077B2) describes a system that includes a sensor positioned above a rack in a space, generating top-view images of the rack and a tracking subsystem that can detect events associated with a person entering a zone adjacent to the rack and removing an item from the shelf. The system can determine which person is associated with the event, store buffer frames of images during the event, and use an action-detection algorithm to identify the person performing the action based on contours associated with each person. The system can assign the action to the respective person based on the detection results.
Furthermore, the system can determine a region-of-interest in the stored frames, evaluate the results of the action-detection algorithm against set criteria, and apply a second action-detection algorithm if needed. The system can also analyze the relative orientation of the persons to the rack to associate them with the event. Additionally, the system can assign the item being picked up to the respective person based on the action detected. The patent also covers a method and a tracking subsystem that perform similar functions, including storing buffer frames, detecting actions, and assigning actions to specific individuals based on image analysis and algorithms, showcasing advancements in tracking and monitoring technology in retail or storage environments.
