Abstract

A digital image capturing and processing system comprising a system housing having an imaging window, a plurality of coplanar illumination and imaging subsystems disposed in the system housing. Each coplanar illuminating and linear imaging station includes a dual-type coplanar linear illumination and imaging engine that supports automatic image formation and detection along each pair of coplanar illumination and imaging planes generated by the coplanar illuminating and linear imaging station. Each pair of coplanar illumination and imaging planes are projected into the 3D imaging volume, for capturing of linear digital images of objects moved therewithin, and subsequent processing thereof for recognizing information graphically represented in the captured linear digital images, and automatic imaging-processing based object motion and velocity detection within the 3D imaging volume.
