Abstract

The invention discloses a paper money discrimination method and a device. The method comprises the following steps: acquiring a transmission image of a region with window-open type safety line indentation characteristics on paper money, wherein the region is transmitted by light beam; and analyzing and recognizing the indentation characteristics in the image so as to determine the authenticity of the paper money. The method and the device of the invention have advantages of good adaptability to various currencies, low hardware cost, a high detection and recognition rate, stable and reliable performance, etc.

Description

technical field [0001] The invention belongs to the field of photoelectric technology, and in particular relates to a banknote authenticating method and device. Background technique [0002] The core problem in the field of financial instruments is the identification of counterfeit banknotes. Security thread is a linear or strip-shaped additive that is continuously put into the paper during papermaking, parallel to the paper surface, and has anti-counterfeiting functions. The earliest safety thread in the world was spun into thread from natural hemp or silk, which was continuously added to the inside of the paper when making paper. At present, the security thread is often based on PET (polyester), on which various visible, optically variable and machine-readable anti-counterfeiting features are loaded. Present banknote security threads are generally 20-40 μm thick, 1-4mm wide, and the length is the same as the width of a single banknote after cutting. Security threads are...
