Patent number: 11974077Abstract: A system includes a sensor, a weight sensor, and a tracking subsystem. The tracking subsystem receives an image feed of top-view images generated by the sensor and weight measurements from the weight sensor. The tracking subsystem detects an event associated with an item being removed from a rack in which the weight sensor is installed. The tracking subsystem determines that a first person or a second person may be associated with the event. In response to determining that the first or second person may be associated with the event, buffer frames are stored of top-view images generated by the sensor during a time period associated with the event. The tracking subsystem then determines, using at least one of the stored buffer frames and a first action-detection algorithm, whether an action associated with the event was performed by the first person or the second person.Type: GrantFiled: October 15, 2020Date of Patent: April 30, 2024Assignee: 7-ELEVEN, INC.Inventors: Shahmeer Ali Mirza, Sailesh Bharathwaaj Krishnamurthy, Sarath Vakacharla, Deepanjan Paul

Patent number: 11861852Abstract: A system includes a sensor and a tracking subsystem. The tracking subsystem receives an image feed of top-view images generated by the sensor. The tracking subsystem detects an event associated with an item being removed from a rack. The tracking subsystem determines that a first person and a second person may be associated with the event. In response, the tracking subsystem dilates contours associated with the first and second person from a first depth to a second depth until the contours enter a zone adjacent to the rack. A number of iterations is determined for each contour to enter the zone adjacent to the rack. If the first person's contour enters the zone in fewer iterations, the item is assigned to the first person.Type: GrantFiled: August 16, 2021Date of Patent: January 2, 2024Assignee: 7-ELEVEN, INC.Inventors: Shahmeer Ali Mirza, Sailesh Bharathwaaj Krishnamurthy, Sarath Vakacharla, Deepanjan Paul

Patent number: 11625923Abstract: A system includes a sensor and a tracking subsystem. The tracking subsystem receives an image feed of top-view images generated by the sensor and detects an event associated with a portion of a person entering a zone adjacent to a rack. The tracking subsystem determines that a first and second person may be associated with the event. The subsystem tracks the item and calculates a velocity of the item as it is moved through the space. The subsystem identifies, based on the calculated velocity, a frame in which the velocity of the item is less than a threshold velocity. The subsystem determines whether the first or second person is nearer the item in the identified frame. If the first person is nearer, the item is assigned to the first person.Type: GrantFiled: March 31, 2021Date of Patent: April 11, 2023Assignee: 7-ELEVEN, INC.Inventors: Shahmeer Ali Mirza, Sailesh Bharathwaaj Krishnamurthy, Sarath Vakacharla, Deepanjan Paul

Patent number: 11568554Abstract: A system includes a sensor and a client. The client receives a set of frames of top-view depth images generated by the sensor. The client identifies a frame of the received frames in which a first contour associated with a first object is merged with a second contour associated with a second object. The client determines, at a first depth in the identified frame, a merged-contour region which is associated with the merged contours. The client detects a third contour at a second depth that is less than the first depth and determines a first region associated with the third contour. The client detects a fourth contour at the second depth and determines a second region associated with the fourth contour. If criteria are satisfied, the client associates the first region with a position of the first object and associates the second region with a position of the second object.Type: GrantFiled: October 25, 2019Date of Patent: January 31, 2023Assignee: 7-ELEVEN, INC.Inventors: Trong Nghia Nguyen, Shahmeer Ali Mirza, Sailesh Bharathwaaj Krishnamurthy, Sarath Vakacharla
