Method and apparatus for product checkout in unmanned store

An unmanned store product checkout apparatus comprising:

• a transfer unit for transferring a product to scan the product desired by a user to purchase;
• a first product recognition unit installed at a first point where transfer of the product begins by the transfer unit, to recognize that the product is placed on the transfer unit;
• a height sensor installed at the first point, to measure the height of the product;
• a weight sensor installed at a lower one side of the transfer unit, to measure a weight of the product;
• a scan unit installed to be spaced apart from the transfer unit as much as a preset distance, to scan a barcode and an image of the product transferred by the transfer unit;
• a processor for identifying what the product is by using artificial intelligence learning data on the basis of the barcode and image of the product scanned by the scan unit and the weight of the product measured through the weight sensor;
• a product alignment unit installed at a second point where scan of a product begins by the scan unit, to align the product so that a recognition rate of the product through scan of the product increases;
• a second product recognition unit installed at a third point where scan of the product by the scan unit is terminated, to recognize that the product has arrived at the third point;
• a product classification unit installed at the third point, to classify the product on the basis of a result of the product identification;
• and
• a control unit for controlling operations of the transfer unit, the product alignment unit, and the product classification unit on the basis of a result of first product recognition performed by the first product recognition unit, the height of the product measured by the height sensor, a result of second product recognition performed by the second product recognition unit, and a result of product identification performed by the processor.
