  • Publication number: 20190045104
    Abstract: An article image capturing apparatus according to an embodiment includes a camera that captures an image of an article. A first lighting unit illuminates a first side of the article facing the camera. The article is positioned between a second lighting unit and the camera. The second lighting unit illuminates a second side of the article. The camera captures a first image of the surface when the first lighting unit is turned on. The camera captures a second image of the surface when the first lighting unit is turned off and the second lighting unit is turned on. A processor determines, based on the second image, an outer shape of the article. The processor extracts, from the first image, an image of the article based on the outer shape of the article. A storage device saves the extracted image of the article.

  • Publication number: 20170255899
    Abstract: An inventory management system includes an image capturing device, a data storage, and a processing device. The processing device is configured to process image data of one or more images of an inventory space for items of a same type captured by the image capturing device, and to extract, from the captured images, an identification code that is unique to the items and placed behind the inventory space when viewed from the image capturing device. When the processing device is able to extract the entire identification code, the processing device causes an update of an inventory record stored in the data storage to indicate that the items are out of stock if the inventory record for the items are present.
