Intelligent system for automatically recognizing objects at a point of sale (POS) station by omni-directional imaging of the objects using a complex of coplanar illumination and imaging subsystems

摘要

A digital image capture and processing system for automatically recognizing objects at a point of sale (POS) station. The system comprising a system housing having an imaging window, and containing a digital image capturing and processing engine including a plurality of coplanar illumination and imaging stations. The stations generate and project a complex of coplanar illumination and imaging planes through the imaging window, and within a 3D imaging volume definable relative to the imaging window for omni-directional imaging of objects passing through the 3D imaging volume, and generate digital linear images of the object as the object intersects coplanar illumination and imaging planes within the 3D imaging volume during system operation. A database is provided for storing one or more object libraries representing objects that can be recognized by the system. A digital image processing subsystem automatically (i) processes digital images generated by said coplanar illumination and imaging stations, (ii) extracts object features from processed digital images, and (iii) recognizes objects which are represented by the object libraries and producing information representative of recognized objects for display at the POS station.
