Patent attributes
Methods of and devices and systems for obtaining and using images of items as the items appear in an inventory area (e.g., storage bin) are disclosed. Images of inventory areas are captured before and after stow or pick operations. A difference between the before and after images is determined and extracted as an image of the item that was stowed or picked. The process may be repeated for numerous units of the item and one or more definitive item images are selected. The definitive item image may be displayed to pickers directly to facilitate picking, or may be used to determine the position of a unit of the item in a particular inventory area such that the position of the item to be picked may be indicated to the picker. Definitive item images may also be used for inventory validation, enforcement of pick and stow etiquette.
