Patent number: 12333491Abstract: Described is a system for counting stacked items using image analysis. In one implementation, an image of an inventory location with stacked items is obtained and processed to determine the number of items stacked at the inventory location. In some instances, the item closest to the camera that obtains the image may be the only item viewable in the image. Using image analysis, such as depth mapping or Histogram of Oriented Gradients (HOG) algorithms, the distance of the item from the camera and the shelf of the inventory location can be determined. Using this information, and known dimension information for the item, a count of the number of items stacked at an inventory location may be determined.Type: GrantFiled: April 18, 2023Date of Patent: June 17, 2025Assignee: Amazon Technologies, Inc.Inventors: Xiaofeng Ren, Avishkar Misra, Ohil Krishnamurthy Manyam, Liefeng Bo, Sudarshan Narasimha Raghavan, Christopher Robert Towers, Gopi Prashanth Gopal, Yasser Baseer Asmi

Patent number: 11977359Abstract: Described is a method for determining when to transition devices between different states based on determined potential activity in an area near the devices. When the potential for activity near an input device is below a threshold, the device is maintained in an inactive state. When the potential for activity near the device exceeds the threshold, the device is transitioned to an active state before the potential activity can occur near the device. Likewise, when the device is in an active state, the implementations described herein provide the ability to determine when to begin and end transmission of data from the device to a remote computing resource for processing. For example, obtained video may be processed locally to determine if an activity is occurring. If an activity is occurring, relevant data is sent to a remote computing resource to determine if an action has been performed during the activity.Type: GrantFiled: March 3, 2021Date of Patent: May 7, 2024Assignee: Amazon Technologies, Inc.Inventors: Sudarshan Narasimha Raghavan, Michel Leonard Goldstein, Fan Sun, Ramanathan Palaniappan

Patent number: 11887046Abstract: A system may use sensor data from a facility to generate tentative values associated with an event, such as the identification of an item removed from a shelf of the facility. A confidence value associated with each of the tentative values may be less than a confidence threshold. In response, inquiry data seeking confirmation of a tentative value from an associate is generated and sent to one or more associates in the facility. Responses from the associates are collected to determine a selection of one of the tentative values. The selected tentative value is designated as output data for the system. Thereafter, the output data and the original sensor data are designated as training data, which can then be used to train or update machine learning systems. Subsequent use of the updated machine learning systems can yield more accurate results.Type: GrantFiled: July 31, 2020Date of Patent: January 30, 2024Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Christopher Andrew Stephens, Alexander Clark Prater, Alexander Michael McNamara, Sridhar Boyapati, David Echevarria Ignacio, David William Bettis, Korwin Jon Smith, Kevin Alexander Lee, Aaron Craig Thompson, Gary Paolo Raden, Sudarshan Narasimha Raghavan, Dilip Kumar, Félix Joseph Étienne Pageau

Patent number: 11657617Abstract: A system may generate image data of users within a facility. Such users may be part of a group that is unknown to the system. The system can predict group data for two or more users based on a resemblance or the users being within a threshold distance of each other. However, if a confidence level associated with the predicted group data is below a threshold value, the group data is deemed unreliable and assistance from an associate is deemed necessary. A user interface that includes a portion of the image data, information about the predicted group data, and other interface elements is presented to the associate via a display. Based on the input data received from the associate, the group data can be confirmed or rejected. If the group data is confirmed, an association is made between the users and a group identifier.Type: GrantFiled: February 14, 2022Date of Patent: May 23, 2023Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Thomas Meilandt Mathiesen, Maren Marie Costa, Nishitkumar Ashokkumar Desai, Christopher Richard Fescoe, Casey Louis Thurston, Jason Michael Famularo, Sudarshan Narasimha Raghavan, Waqas Ahmed, Danny Guan

Patent number: 11250272Abstract: In one or more implementations, groups of users enter a facility within a short time. Automated systems attempt to predict a grouping for various users, but the predicted grouping may not exhibit a confidence level above a certain threshold level. In such cases, a user interface is generated and presented to an associate to confirm the grouping of users. The user interface includes an image gallery and interface elements that allow for the selection of users into a group. The image gallery includes previously stored images of users, such as images obtained during a registration process or during a previous visit to the facility. In addition, the user interface also includes image data obtained from a camera at the facility depicting visitors at various times or locations. Once a grouping has been selected or confirmed by an associate, group data may be generated and stored for the group of users.Type: GrantFiled: October 11, 2019Date of Patent: February 15, 2022Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Thomas Meilandt Mathiesen, Maren Marie Costa, Nishitkumar Ashokkumar Desai, Christopher Richard Fescoe, Casey Louis Thurston, Jason Michael Famularo, Sudarshan Narasimha Raghavan, Waqas Ahmed, Danny Guan
