Method, System and Apparatus for Detecting Item Facings

Abstract:

A method by an imaging controller of detecting item facings from image sensor data includes: obtaining, at the imaging controller, the image sensor data corresponding to a support structure containing at least one item; identifying, by a feature detector of the imaging controller, a set of matched keypoint pairs from keypoints of the image sensor data; determining, by a peak detector of the imaging controller, a separation distance between the keypoints of each matched keypoint pair; detecting, by the peak detector, a count of item instances represented in the image sensor data based on the separation distances; and presenting item facing detection output including the count of item instances.
