DETERMINING ITEM QUANTITY AT CHECKOUT

Abstract: a depth image of items on a scale are captured. depth information for the depth image is processed to produce a three-dimensional (3d) map of the depth information. the items are identified as blobs within the 3d map. a plane is generated and projected into the 3d map and each separate blob that intersects the plane is counted to determine an item quantity for the items depicted in the original depth image. the item quantity is provided back to a terminal for item quantity verification of the items during a checkout transaction at the terminal. in an embodiment, the plane is projected onto the 3d map and animated to move from a top of the 3d map to a bottom of the 3d map while the separate blobs are counted for the item quantity determination as the plane moves.
