  • Patent number: 12243310
    Abstract: An article determination apparatus (10) is used with two image capture units (20). One image capture unit (20), an article shelf (40), and the other image capture unit (20) are arranged in this order. The acquisition unit (110) acquires images generated by the two image capture units (20). The image processing unit (120) generates first size data and second size data by processing the images acquired by the acquisition unit (110). The first size data and the second size data indicate the size of an area in which an article is captured in an image generated by one image capture unit (20) and by the other image capture unit (20), respectively. The determination unit (130) determines that an estimation result of the article name of the article by image processing is correct when a relation between the first size data and the second size data satisfies a criterion.

  • Publication number: 20240242577
    Abstract: An image acquisition unit (11) acquires a recognition processing image. A recognition unit (12) recognizes a product in the recognition processing image based on an estimation model. A registration unit (13) registers a result of the recognition in recognized product information. An output unit (14) outputs a result of the recognition. A correction reception unit (16) receives an input for correcting a result of the recognition. A correction unit (17) changes a result of the recognition to a result of the recognition after a correction, and also stores correction information in which a result of the recognition after a correction and the recognition processing image are associated with each other. A learning unit (18) performs relearning by using the recognition processing image stored as the correction information and updates the estimation model, when a number of the recognition processing image stored exceeds a predetermined value.
