Real-Time Three-Dimensional (3D) Shape Validation

Abstract:

A three-dimensional image (3D) image for a shape of an orientation of an item is captured when an item barcode for the item is captured by a scanner during item checkout at a terminal. Edges for the shape and dimensions for the shape are calculated from the 3D image based on the orientation. The shape dimensions are compared against expected dimensions for a candidate item that is identified from item information in the item barcode and a decision is made as to whether to validate the item barcode for the item during item checkout or as to whether to invalidate the item barcode and suspend item checkout at the terminal for an audit of the item checkout.
