Abstract

A digital image capturing and processing system for automatically recognizing objects in a POS environment. The system includes a system housing having an imaging window; illumination and imaging stations for generating and projecting illumination and imaging planes or zones through the imaging window, and into a 3D imaging volume definable relative to the imaging window, for digital imaging an object passing through the 3D imaging volume, and generating digital linear images of the object as the object intersects the illumination and imaging planes or zones during system operation. A digital image processor processes the digital images and automatically recognizes the object, such as produce and fruit, graphically represented by the digital images.
