Abstract
A method of optimizing a pick list using image data from a barcode scanner. An example method includes comparing a reference background image captured by a scanner to an image of a produce item to be purchased, calculating attributes from the image, comparing the calculated attributes to reference produce attributes in a produce database, selecting reference produce attributes associated with reference produce items that are closest to the calculated attributes as the top candidates in the pick list.
Claims17
A pick list optimization method comprising:
- capturing, by a scanner, an image of an item to be purchased when the item is sensed on an weigh plate of the scanner that is integrated into the scanner by directing the image of the item from a horizontal mirror situated beneath the weigh plate to a camera of the scanner and capturing the image by the camera, wherein capturing further includes controlling, by the scanner, a level of illumination from scan field lighting to minimize glare while the camera captures the image;
- calculating, by executable instructions executing on a processor from a non-transitory computer-readable storage medium, attributes from the image;
- comparing, by the executable instructions, calculated attributes to reference item attributes in an item database;
- selecting, by the executable instructions, reference item attributes associated with reference items that are closest to the calculated attributes as top candidates in a pick list;
- and
- displaying, by the executable instructions, the pick list with the top candidates within a transaction screen for a transaction at a Point-Of-Sale (POS) terminal.

- extracting, by the executable instructions, a foreground image substantially containing only produce item;
- applying, by the executable instructions, a color correction to the extracted image to enhance its color accuracy and produce a color corrected image;
- calculating, by the executable instructions, attributes from the color corrected image;
- comparing, by the executable instructions, calculated attributes to reference produce attributes in a produce database;
- selecting, by the executable instructions, reference produce attributes associated with reference produce items that are closest to the calculated attributes as top candidates in a pick list;
- sending, by the executable instructions, the top candidates to a point of sale (POS) system for display;
- displaying, by the POS system, the top candidates in a pick list on a POS display within a transaction screen during a transaction with the POS system.

A scanning system comprising:
- a scanner;
- lighting;
- a processor configured to activate the scanner to capture an image of an item when the item is sensed on an weigh plate of the scanner that is integrated into the scanner by directing the image of the item from a horizontal mirror situated beneath the weigh plate to a camera of the scanner and capturing the image by the camera, to activate the lighting during operation of the camera for the scanner, to control a level of the lighting to minimize glare while the image of the item is captured by the camera, to calculate attributes from the image, to compare the attributes to reference item attributes in an item database, select reference item attributes associated with reference items that are closest to the calculated attributes as top candidates in a pick list, and display the pick list within a transaction screen on a Point-Of-Sale (POS) display during a transaction.
