Abstract

A tunnel-type digital imaging-based self-checkout system capable of generating and projecting coplanar illumination and imaging planes into a 3D imaging volume within a tunnel structure. The tunnel structure is supported above a package conveyor in a retail POS environment, and employs automatic package identification, profiling and tracking techniques during self-checkout operations.
