Abstract

A shelf system includes: a shelf body with at least one storage space; an item identification pattern on a horizontal edge of the storage space and extending by a preset length along a length direction of the horizontal edge; an image capture unit configured to obtain image information of the storage space, the image information including the item identification pattern; and a processor configured to, based on the image information, determine storage situation of a matching item that matches the item identification pattern and is stored in a preset placement range in the storage space. The preset placement range is an extension space which is in the storage space and which is defined by a horizontal plane corresponding to an extension range of the item identification pattern by a preset extension length. There is a preset correspondence relationship between the item identification pattern and the matching item.
