APPARATUS AND METHOD FOR RECOGNIZING STAMPED CHARACTER AND SYSTEM FOR DETECTING STAMPED DEPTH OF CHARACTER USING THE SAME

摘要

An apparatus and a method recognizes stamped characters, detects stamped depths of characters using the same, and/or accurately recognizes characters even when an image distortion occurs at stamped portion due to different stamped depths of characters.

主权项

1. An apparatus for recognizing stamped characters, comprising:
a stamped character photographing unit that photographs stamped characters using lighting devices having different wavelengths; an image segmentation unit that segments images photographed by the stamped character photographing unit into each wavelength; an image synthesis unit that synthesizes binarization images for each wavelength segmented by the image segmentation unit; and a recognition control unit that recognizes the stamped characters in the image synthesized by the image synthesis unit.
