Distinguishing Between Stock Keeping Units Using a Physical Dimension of a Region Depicted in an Image

摘要

The disclosure includes a system and method for distinguishing between stock keeping units of similar appearance that vary in size. An image recognition application receives an image including a shelving unit stocking a plurality of items, identifies each item in the image, generates a region of interest for each identified item in the image, identifies a physical dimension of a portion of region depicted in the image, determines a dimension of the region of interest for each identified item and the portion of region in pixels, determines a pixel-to-physical dimension ratio using the dimension in pixels of the portion of region and the physical dimension of the portion of region depicted in the image, and determines a stock keeping unit identifier of each identified item in the image based on the pixel-to-physical dimension ratio and the dimension of the region of interest for each identified item.

主权项

1. A method comprising:
receiving, by an image processor, an image including a shelving unit stocking a plurality of items; generating, by the image processor, a region of interest for an identified item in the image; identifying, by the image processor, a physical dimension of a region depicted in the image; determining, by the image processor, a dimension of the region of interest for the identified item and for the region in the image, wherein the dimension is expressed in pixels; determining, by a pixel-to-physical dimension ratio engine, a pixel-to-physical dimension ratio using the dimension of the region and the physical dimension of the region depicted in the image; and determining, by a size engine, a stock keeping unit identifier of the identified item in the image based on the pixel-to-physical dimension ratio and the dimension of the region of interest for the identified item.
