摘要:
The invention relates to a ultraviolet anti-counterfeiting check verification method which solves subjective defect and time consuming problems of the traditional verification methods, and comprises the following steps: a. collecting ultraviolet gray level image by a 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 pixels of the ultraviolet gray level image and the first binary image; e. determining a top left corner locating position of a first binary image rectangle; f. extracting a second binary image from the tilt corrected ultraviolet gray level image; g. performing position correction on the second binary image of a check to be verified; and h. calculating the matching degree between the second binary image of the check to be verified and a second binary image of a real check to verify authenticity.
