METHOD AND DEVICE FOR RETAIL GOODS IDENTIFICATION Russian patent published in 2023 - IPC G06Q30/06 G06V10/22 G06V10/24 G06V10/40 G06V20/68 

FIELD: goods identification.

SUBSTANCE: methods for identification retail goods located on supermarket shelves. The product identification device contains a camera connected to an inertial measuring unit and a detector, a computing unit connected to an inertial measuring unit and a detector, a database, a comparison unit connected to the computing unit and the database. To identify the goods, an image of the rack with goods is taken using a camera. The angle between the optical axis of the camera when shooting and the direction of gravity is determined. An image of a product from a shelf caught in the captured image is detected. The position of the center of each bounding box in the image captured by the camera is determined. The angle between the horizontal plane and the ray connecting the center of the camera lens and the center of the bounding box is calculated. A set of images of known products is retrieved from the database, from which the image that has the highest degree of agreement with the detected image of the product from the shelf is selected, and the product is identified.

EFFECT: increasing the accuracy of identification of goods located on the shelf of the rack.
