Abstract: An item stowed at an inventory location may rest on a surface such as a shelf or may be supported above the surface. The item may exhibit a footprint that is representative of a physical perimeter of the item. For example, the footprint may be an edge of a shadow cast by the item. Information about a size and shape of a footprint associated with a particular item may be stored. An optical sensor array may acquire sensor image data indicative of the footprint of one or more of the items stored at an inventory location. A quantity of items at the inventory location may be determined by comparing the sensor image data with the stored data.

Abstract: 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.

Abstract: Sensors in a facility generate sensor data associated with a region of the facility, which can be used to determine a 3D location of an object in the facility. Some sensors may sense overlapping regions of the facility. For example, a first sensor may generate data associated with a first region of the facility, while a second sensor may generate data associated with a second region of the facility that partially overlaps the first region. Sensors may fail at times as determined from sensor output data or status data. In response to identifying a failed sensor, an undetected region corresponding to the failed sensor is identified, as well as a substitute sensor that partially senses the undetected region. Sensor data from the substitute sensor, such as 2D data, is acquired and used to estimate a 3D location of an object in the undetected region.

Abstract: Described is a multiple-camera system and process for determining an item involved in an event. For example, when a user picks an item or places an item at an inventory location, image information for the item may be obtained and processed to identify the item involved in the event and associate that item with the user.

Abstract: Frames of sensor data may be obtained from many sensors arranged throughout a facility. These frames may be time synchronized to support further processing. For example, frames containing image data obtained at about the same time from many cameras within the facility may be used to create an aggregate or “stitched” view of the facility at that time. The synchronization may involve storing the frames from several sensors in buffers. A time window may be specified and used in conjunction with timestamps of the frames to select a set of sensor data from the buffers that are deemed to be synchronized data. The synchronized data may then be used for further processing.

Abstract: This disclosure describes an item drop location for placing items that have been picked from an inventory location within a material handling facility but have not yet been transitioned from the materials handling facility and a return location for returning items that have been transitioned from the materials handling facility. Likewise, described is a system and method for identifying an item placed at a drop location or an item placed at a return location, processing the placed item and providing confirmation to a user that placed the item and facilitating a return of the item or a removal of the item from an item identifier list associated with the user.

Abstract: This disclosure describes a system for assisting users in locating items from inventory locations and/or obtaining additional information about items. In some instances, a user may experience difficulty in locating an inventory item in a materials handling facility. By detecting one or more expressions presented by the user, an inventory management system may determine that assistance is to be provided to the user, determine and provide the appropriate assistance to the user.

Abstract: Systems involving a plurality of cameras with clocks may not remain time synchronized during operation. Described in this disclosure are techniques for synchronizing one or more of the clocks of a plurality of cameras or the images produced by the plurality of cameras. In one implementation, a timestamp projector produces an optical timestamp encoding data indicative of timing. One or more cameras may acquire images of a scene that include the optical timestamp. The images may be processed to recover the data indicative of timing. This data may be used to set the clock of the camera, set timestamps associated with the images for subsequent use, and so forth.
