Method of reading bar code symbols on objects at a point-of-sale station by passing said objects through a complex of stationary coplanar illumination and imaging planes projected into a 3d imaging volume

Abstract

Digital image capture and processing systems and methods for generating and projecting coplanar illumination and imaging planes and/or coextensive area-type illumination and imaging zones, through one or more imaging windows, and into a 3D imaging volume in a retail POS environments, while employing automatic object motion and/or velocity detection, real-time image analysis and other techniques to capture and processing high-quality digital images of objects passing through the 3D imaging volume, and intelligently controlling and/or managing the use of visible and invisible forms of illumination, during object illumination and imaging operations, that might otherwise annoy or disturb human operators and/or customers working and/or shopping in such retail environments.
