Abstract: A method of object status detection for objects supported by a shelf, from shelf image data, includes: obtaining a plurality of images of a shelf, each image including an indication of a gap on the shelf between the objects; registering the images to a common frame of reference; identifying a subset of the gaps having overlapping locations in the common frame of reference; generating a consolidated gap indication from the subset; obtaining reference data including (i) identifiers for the objects and (ii) prescribed locations for the objects within the common frame of reference; based on a comparison of the consolidated gap indication with the reference data, selecting a target object identifier from the reference data; and generating and presenting a status notification for the target product identifier.

Abstract: A product status detection system includes a mobile automation apparatus having a sensor to capture data representing a shelf supporting products, responsive to data capture instructions. The system includes a server in communication with the mobile apparatus, having: a mobile apparatus controller to generate data capture instructions for the mobile apparatus; a repository to store captured data from the mobile apparatus; a primary object generator to generate primary data objects from the captured data, each including a location in a common frame of reference; a secondary object generator to generate and store secondary data objects based on the primary data objects; a detector to identify mismatches between reference data and the secondary data objects; and an alert generator to select a subset of the mismatches, and generate and transmit a status alert corresponding to the subset. The system also includes a client device to receive and display the status alert.
