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.

A method of extracting price text from an image set includes: obtaining input data comprising (i) a plurality of images depicting shelves supporting products, and (ii) for each of the images, a set of text regions and corresponding price text strings; registering the images to a common frame of reference; identifying a subset of the text regions having overlapping locations in the common frame of reference; selecting one of the text regions from the subset; and presenting the price text string corresponding to the one of the text regions for further processing.

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.

A method in an imaging controller of correcting translucency artifacts in data representing one or more objects disposed on a shelf includes: obtaining a plurality of depth measurements captured by a depth sensor and corresponding to an area containing the shelf; obtaining (i) a definition of a plane containing edges of the shelf, (ii) a location in the plane of an upper shelf edge, and (iii) a location in the plane of a lower shelf edge adjacent to the upper shelf edge; generating a depth map containing, for each of a plurality of positions in the plane, a nearest object depth; detecting an upper object boundary in the depth map between the upper and lower support surface edges; updating each nearest object depth between the upper object boundary and the lower shelf edge to contain a depth of the upper object boundary; and storing the corrected depth map.
