Embodiment Construction

[0019] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, a banknote detection system includes a Yuanyang number identification and verification system for detecting the consistency of the horizontal and vertical numbers of the banknotes and the number on the back of the dirty number, and an OCR identification and verification system for detecting the consistency of the banknote invalid ticket and replacement ticket number ;

[0021] The Yuanyang number identification and verification system includes a double-sided image acquisition unit for image acquisition of the set positions on both sides of the banknote, a number identification and comparison unit for number identification and comparison of the images collected by the double-sided image acquisition unit, and A print-through detection unit that detects anti-dirty conditions according to the reverse image collected by the...

Abstract

The invention discloses a bill mandarin-duck-number recognition and check system. The system comprises a double-sided image acquisition unit, a number recognition and comparison unit and a strike-through detection unit, wherein the double-sided image acquisition unit is used for collecting images of set positions of the obverse side and the reverse side of a bill; the number recognition and comparison unit is used for conducting number recognition and comparison on the images collected by the double-sided image acquisition unit; the strike-through detection unit is used for detecting the anti-offset condition of the reverse side image collected by the double-sided image acquisition unit. Through the bill mandarin-duck-number recognition and check system, a horizontal row of numbers and a vertical row of numbers of each bill can be compared and checked, the comparison and check speed is high, comparison and check are more accurate, the labor intensity of workers is lowered, the detection efficiency is improved, and the bill printing quality is improved.

Description

technical field [0001] The invention relates to the field of banknote printing and minting, in particular to a paper banknote mandarin duck number identification and verification system. Background technique [0002] Banknote printing requires a high degree of precision, and each banknote needs to be carefully inspected. The consistency of the detection number is particularly important, that is, the horizontal number and the vertical number on the same banknote must be exactly the same, and when a banknote When the horizontal number and the vertical number on the banknote are inconsistent, it is called a mandarin duck number. When the Yuanyang sign appears on a banknote, the banknote needs to be invalidated. Similarly, when other printing errors occur, such as when a banknote prints through (that is, the number on the back is dirty), it is also necessary to pull out the banknote and invalidate it. [0003] And all the banknotes that are invalidated need to be supplemented ...
