Publication number: 20240029274Abstract: A reference depth image of a platform is captured using a three-dimensional (3D) sensor. A plurality of secondary depth images are captured, wherein for each secondary depth image, a depth difference parameter is determined by comparing the secondary depth image and the reference depth image. In response to determining that the depth difference parameter has stayed constant at a value higher than zero for a duration of a first time interval, it is determined that an item has been placed on the platform.Type: ApplicationFiled: September 28, 2023Publication date: January 25, 2024Inventors: Xinan Wang, Kyle J. Dalal, Fahad Mirza, Jon Andrew Crain

Publication number: 20240029276Abstract: In response to detecting a first triggering event corresponding to placement of a first item on a platform, a plurality of first images are captured of the first item and a plurality of cropped first images are generated based on the first images. A first item identifier associated with the first item is identified based on the cropped first images. In response to detecting a second triggering event corresponding to placement of a second item on the platform, a plurality of second images of the first item are captured and a plurality of cropped second images are generated from the second images. In response to determining that the cropped first images match with the cropped second images, the first item identifier is assigned to the first item depicted in the second images.Type: ApplicationFiled: September 28, 2023Publication date: January 25, 2024Inventors: Xinan Wang, Kyle J.

Publication number: 20240029277Abstract: A device for object tracking receives an image from a camera, where the image shows a set of points on a calibration board placed on a platform. The device determines a pixel location array that comprises pixel locations associated with the points in the image. The device determines, by applying a first homography to the pixel location array, a calculated location array identifying calculated physical location coordinates of the set of points in the global plane. The device determines that the difference between a reference location array and the calculated location array is more than a threshold value. In response, the device determines that the camera and/or the platform has moved from a respective initial location when the first homography was determined. The device determines a second homography by multiplying an inverse of the pixel location array by the reference location array and calibrates the camera using the second homography.Type: ApplicationFiled: September 28, 2023Publication date: January 25, 2024Inventors: Xinan Wang, Kyle J. Dalal, Fahad Mirza, Jon Andrew Crain, Shahmeer A. Mirza

Patent number: 11823396Abstract: A scalable tracking system includes a camera subsystem, a weight subsystem, and a central server. The camera subsystem includes cameras that capture video of a space, camera clients that determine local coordinates of objects in the captured videos, and a camera server that determines the physical positions of objects in the space based on the determined local coordinates. The weight subsystem determines when items were removed from shelves. The central server determines which object in the space removed the items based on the physical positions of the objects in the space and the determination of when items were removed.Type: GrantFiled: November 29, 2021Date of Patent: November 21, 2023Assignee: 7-ELEVEN, INC.Inventors: Sailesh Bharathwaaj Krishnamurthy, Sarath Vakacharla, Trong Nghia Nguyen, Shahmeer Ali Mirza, Madan Mohan Chinnam, Caleb Austin Boulio, Deepanjan Paul, Fahad Mirza

Patent number: 11501454Abstract: An item position tracking system includes weight sensors each associated with a weight board. Each weight sensor transmits sensor data indicative of a weight of an item to its corresponding weight board. Each weight board is configured to assign a particular address number to its corresponding weight sensor. The weight boards transmit the sensor data and the address numbers to a circuit board that transmits the sensor data and the address numbers to a weight server. The weight server determines from which weight sensor data is originated based on the address numbers, and whether items were removed from the weight sensors.Type: GrantFiled: November 25, 2020Date of Patent: November 15, 2022Assignee: 7-ELEVEN, INC.Inventors: Fahad Mirza, Kyle Dalal, Ryan Jerman Jones, Shahmeer Ali Mirza

Patent number: 11450011Abstract: A system includes a weight sensor and a weight server. The weight sensor generates a signal indicative of a weight of at least one of an item. The weight server detects an event corresponding to a weight change on the weight sensor when a quantity of the item is removed from the weight sensor. The weight server determines the item quantity by calculating a result of dividing the weight change over a unit weight of the item. If the result is within a threshold range from an integer that is closest to the result, the weight server determines that a quantity of the item with the amount of the integer is removed from the weight sensor. If the result is not within the threshold range from the integer, the weight server uses weight change patterns of historically observed signals to determine item quantity that was removed from the weight sensor.Type: GrantFiled: November 25, 2020Date of Patent: September 20, 2022Assignee: 7-ELEVEN, INC.Inventors: Xinan Wang, Fahad Mirza, Shahmeer Ali Mirza
