Distinguishing Between Stock Keeping Units Using Marker Based Methodology

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 depicting a plurality of items, the image including a reference marker with a known physical dimension. The image recognition application performs image recognition to identify an item in the image and a region of interest for the identified image. The image recognition application further determines a pixel-to-physical dimension ratio using the dimension of a region of interest of the reference marker and the known physical dimension of the reference marker. Finally, the image recognition application determines a stock keeping unit identifier of the identified item in the image based on the pixel-to-physical dimension ratio and a dimension of the region of interest of the identified item.

主权项

1. A method comprising:
receiving a first image including a plurality of items, the plurality of items including a reference marker with a known physical dimension; performing image recognition to identify an item in the first image and a region of interest of the identified item in the first image; determining a pixel-to-physical dimension ratio using a pixel dimension of a region of interest of the reference marker and the known physical dimension of the reference marker; and determining a stock keeping unit identifier of the identified item in the first image based on the pixel-to-physical dimension ratio and a dimension of the region of interest of the identified item.
