An omni-directional digital image capturing and processing system comprising a plurality of coplanar illumination and imaging stations for producing a plurality of coplanar linear illumination and imaging planes which intersect within a 3D imaging volume. Each coplanar illumination and imaging station includes a linear image detection array, a linear illumination array, and an object motion and velocity detection subsystem for automatically detecting the motion and velocity of an object that passes through at least a portion of one coplanar linear illumination and imaging plane, and automatically adjusting one or more parameters relating to the exposure and/or illumination control within the coplanar illumination and imaging station. By virtue of the present invention, it is possible to capture and process high quality digital images of objects passed through 3D imaging volumes, at point-of-sale (POS) retail stations and like environments.
