ULTRAVIOLET ANTI-COUNTERFEITING CHECK AUTHENTICITY VERIFICATION METHOD

摘要

Disclosed is an ultraviolet anti-counterfeiting check authenticity verification method, which solves the problems that a conventional verification method relies on subjectivity and is time-consuming and labor-consuming. The method comprises the following steps: a), collecting an ultraviolet gray level image by using an ultraviolet scanner; b), extracting a first binary image from the ultraviolet gray level image; c), calculating a tilt angle of the first binary image; d), calculating tilt correction positions of all pixels of the ultraviolet gray level image and the first binary image; e), determining a positioning position at the upper left corner of a rectangular frame of the first binary image; f), extracting a second binary image from the ultraviolet gray level image after tilt correction; g), performing position correction on the second binary image of a check to be verified; and h), calculating a matching degree between second binary images of the check to be verified and an authentic check to verify the authenticity.
