Abstract

In some embodiments, apparatuses and methods are provided herein useful to detecting a mis-scan of an item. In some embodiments, there is provided a system for detecting a mis-scan of an item for purchase comprising a checkout station; a first staging location; a second staging location; a first area of interest at the checkout station; a second area of interest at the checkout station; a camera; and a control circuit configured to: receive an identifier of a first item; detect a hand of a user purchasing the first item, the first item, and a scanner on a first image captured by the camera; in response to the detection of the hand, the first item, and the scanner, initiate detection of mis-scan items during a checkout process; determine that a payment transaction has been received; and stop the detection of mis-scan items.

Claims29

Dependent claims

A system for detecting a mis-scan of an item for purchase at a checkout station of a retail store, the system comprising:

a checkout station of a retail store comprising a scanner to capture an identifier associated with a first item of a plurality of items for purchase;
a first staging location to secure the plurality of items before the items pass by the scanner;
a second staging location to secure the plurality of items after the items pass by the scanner;
a first area of interest at the checkout station comprising a first proximate area encompassing the scanner and within a first threshold distance from the scanner;
a second area of interest at the checkout station comprising a second proximate area within a second threshold distance from the scanner, wherein the second area of interest encompasses the second staging location and is larger than the first area of interest;
a camera to:
capture a first image of the first area of interest at a first time during a checkout process;
and
capture one or more images of the second area of interest at a subsequent time;
and
a control circuit communicatively coupled to the scanner and the camera, the control circuit to:
receive the identifier of the first item;
detect a hand of a user purchasing the first item, the first item, and the scanner in the first image captured by the camera at the first time;
in response to the detection of the hand, the first item, and the scanner, initiate detection of mis-scan items during the checkout process, wherein the detection of mis-scan items is based at least on the plurality of items detected at the second staging location in the captured one or more images of the second area of interest at the subsequent time and receipt of one or more identifiers associated with the plurality of items located in the first staging location;
determine that a payment transaction has been received from a user purchasing the first item;
and
in response to the receipt of the payment transaction, stop the detection of mis-scan items.

at least one camera to:
capture a first image of the first area of interest at a first time during a checkout process;
and
capture one or more images of the second area of interest at a subsequent time;
and
a control circuit communicatively coupled to the scanner and the at least one camera, the control circuit to:
receive the identifier of the first item;
detect a hand, the first item, and the scanner at the first area of interest in the first image captured by the at least one camera at the first time;
and
in response to the detection of the hand, the first item, and the scanner, initiate detection of mis-scan items during the checkout process, wherein the detection of mis-scan items is based at least on the plurality of items detected at the second staging location in the captured one or more images of the second area of interest at the subsequent time and receipt from the scanner of one or more identifiers associated with the plurality of items.
