Abstract
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.
