Abstract:
1. A tunnel-type digital imaging-based system for use in checkout operations in retail store environments, said tunnel-type digital imaging-based system comprising: a conveyor structure installed at a retail point of sale (POS) station; a tunnel housing arrangement having an input port and an output port, and supported over said conveyor structure so that said conveyor structure transports objects from said input port to said output port, through said tunnel housing arrangement, during tunnel scanning operations; first and second dual PLIIM-based digital linear imaging panels (DIPs) mounted within said tunnel housing arrangement, and arranged on the opposite sides of said conveyor structure; wherein said first dual PLIIM-based DIP contains (i) a first planar light illumination and imaging module (PLIIM # wherein said second dual PLIIM-based DIP contains (i) a third planar light illumination and imaging module (PLIIM # wherein said PLIB# wherein said PLIB# a single PLIIM-based digital linear imaging panel (DIP) arranged on the upper side of said tunnel housing arrangement, above said conveyor structure, and containing (i) a fifth planar light illumination and imaging module (PLIIM # wherein said first, second, third, fourth and fifth coplanar illumination and imaging planes intersect within said 3D digital imaging volume above said conveyor structure, and within said tunnel housing arrangement, and support omni-directional imaging of objects passed therethrough during tunnel scanning operations so as to capture digital linear images of said objects; and a digital image processor for processing said digital linear images generated by said PLIIMs so as to read code symbols on said objects, and identify each said object being transported through said tunnel housing arrangement.
