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.

A method by an imaging controller of detecting item facings from image sensor data, the method comprising:
- 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.
A computing device, comprising:
- a feature detector configured to:
- obtain image sensor data corresponding to a support structure containing at least one item;
- and
- identify a set of matched keypoint pairs from keypoints of the image sensor data;
- a peak detector configured to:
- determine a separation distance between the keypoints of each matched keypoint pair;
- detect a count of item instances represented in the image sensor data based on the separation distances;
- and
- a boundary generator configured to present item facing detection output including the count of item instances.
A non-transitory computer-readable medium storing computer executable instructions that when executed by a processor cause the processor to perform the operations of:
- obtaining image sensor data corresponding to a support structure containing at least one item;
- identifying a set of matched keypoint pairs from keypoints of the image sensor data;
- determining a separation distance between the keypoints of each matched keypoint pair;
- detecting 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.
