Assignee:

APOLLO SYSTEMS, LLC - Boxborough MA

International Classification:

H04N 7/18

US Classification:

348 92

Abstract:

An apparatus to conduct an inspection of printed impressions placed on a conveyor transport system which is synchronized with an optical collection device that captures and digitizes the image of the impressions. The images are then reformatted and analyzed for defects using a reference image. The images are also filtered and converted to an LCH representation which further inspected using the CIE methodology. The final results of the inspection are presented to the operator in real time on a display monitor.

Abstract:

The edges of address elements such as address labels and window apertures located on a mailpiece, are detected by utilizing illumination from first and second alternating "on" and "off" light sources which illuminate the address elements at an acute angle. In the case of label detection, the edge closest to the on illuminating source generates a high contrast image, while the edge furthest from the "on" illuminating source is shadowed. In the case of illumination of an aperture, the opposite is true. That is, the light reflected from the edge which is furthest from illuminating source is high contrast, while edge closest to the illuminating source has a lower contrast. When the images generated due to edge illumination by the left and right light sources are subtracted from each other, the edges are further enhanced due to the fact that the remaining portions of the images cancel each other out.
