Image overlaying and comparison for inventory display auditing

摘要

Example methods disclosed herein to perform inventory display auditing include comparing a reference image of an inventory display obtained during a prior audit of the inventory display with a current image captured by a camera to determine whether the current image corresponds to the same inventory display as the reference image. Disclosed example methods also include, when the current image is determined to correspond to the same inventory display as the reference image, identifying a difference region in the current image corresponding to a portion of the inventory display that changed relative to the prior audit. Disclosed example methods further include, while the current image is displayed on a display screen, modifying a characteristic of the current image in the difference region to indicate a change in product inventory in the portion of the inventory display.

1. A method to perform inventory display auditing, the method comprising:
comparing, by executing an instruction with a processor, a reference image of an inventory display obtained during a prior audit of the inventory display with a current image captured by a camera to determine whether the current image corresponds to the same inventory display as the reference image; when the current image is determined to correspond to the same inventory display as the reference image, identifying, by executing an instruction with the processor, a difference region in the current image corresponding to a portion of the inventory display that changed relative to the prior audit; and while the current image is displayed on a display screen, overlaying, by executing an instruction with the processor, an outline and text on the difference region in the current image to indicate a change in product inventory in the portion of the inventory display.
