System and method for tracking refrigerator inventory based on per-camera changes in sizes of bounding boxes encompassing inventory objects

Abstract

A refrigerator system includes a main body, at least one camera and at least one computing device in operable connection with the camera(s). The camera(s) is/are positioned to have a field of view that includes an entrance opening leading to a storage compartment(s) and is/are configured to capture images of an item being loaded into or being removed from the storage compartment(s). The computing device(s) is/are configured to instruct the camera(s) to capture the images, to analyze the captured images and generate a bounding box around an object of interest in the captured images that contain the object of interest, and to assign a direction of movement for the object of interest being at least one of into, out of or internally within the refrigerated enclosure. The direction of movement is assigned based on changes in size of the bounding box around the object of interest among the analyzed images.
