摘要： An apparatus includes a memory and processor. The memory stores a machine learning algorithm configured to decide whether to use a virtual shopping cart to verify all or a portion of a transaction performed with an algorithmic shopping cart. The processor receives feedback for a decision made by the algorithm, indicating whether the algorithmic and virtual carts match. The processor assigns a reward to the feedback. A first positive reward is assigned when the virtual shopping cart is not used for verification, and the feedback indicates that the carts match. A second positive reward is assigned when the virtual cart is used for verification, and the feedback indicates that the carts do not match. A first negative reward is assigned when the virtual shopping cart is not used for verification, and the feedback indicates that the carts do not match. A second negative reward is assigned when the virtual cart is used for verification, and the feedback indicates that the carts match. The processor uses the reward to update the algorithm.

摘要： An image sensor is positioned such that a field-of-view of the sensor encompasses portion of a beverage machine. The field-of-view includes a zone associated with operating the beverage machine. A subsystem receives a signal indicating beverage is dispensed and angled-view images from the image sensor. First image(s) associated with a start of beverage being dispensed are determined by detecting a hand of a person entering the zone associated with operating the beverage machine. A first identifier is determined for the person in the first image(s). Second image(s) associated with an end of the beverage being dispensed are determined by detecting a hand of the person exiting the zone. A second identifier is determined for the person in the second image(s). If the first identifier is the same as the second identifier, the beverage is assigned to the person with the first identifier.

摘要： An image sensor is positioned such that a field-of-view of the sensor encompasses portion of a beverage machine. The field-of-view includes a first zone associated with operating the beverage machine to dispense the beverage and a second zone in which a cup is placed to receive the beverage. A beverage assignment subsystem receives angled-view images from the image sensor. An event associated with an object entering one or both of the first zone and the second zone is detected. In image(s) associated with a start of the event, it is determined that both a hand of a person enters the first zone and the cup is placed in the second zone. If the cup remained in the second zone for at least a threshold time, the beverage is assigned to the person whose hand entered the first zone.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
