Embodiment Construction
[0062] The embodiments of the present invention will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the embodiments of the present invention, rather than to limit the embodiments of the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the embodiments of the present invention.
[0063] refer to figure 1 , figure 1 It is a schematic flowchart of a banknote identification method provided by an embodiment of the present invention.
[0064] Such as figure 1 As shown, the method for banknote identification includes:
[0065] Step 101, intercepting a characteristic region from the banknote to be identified, and performing binarization processing on the characteristic region;
[0066] Specifically, such as Figures 2 to 5 as shown, figure 2 ...

The invention discloses a paper money identifying method and apparatus. The method comprises the following steps; intercepting a characteristics area from the paper money to be identified; performing binary processing to the characteristics area; obtaining a to-be-identified area of the characteristics area subjected to the binary processing; matching a template separately with a paper money denomination value area after the binary processing and a background area after the binary processing; determining whether the paper money denomination value area after the binary processing matches the template or not; and determining whether the background area after the binary processing matches the template or not; and if the paper money denomination value area after the binary processing and the background area after the binary processing both match the template, then determining a successful matching of the paper money to be identified. According to the invention, the height of the character denomination of the paper money is used to remove the influence of a security line on the impact other than the height, therefore, increasing the accuracy for matching. As for the template similarity processing, a mode is used featuring the matching of the position points and the matching of the numbers of the background points corresponding to a target so as to increase the accuracy for matching.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of banknote inspection, and in particular to a method and device for banknote identification. Background technique [0002] Banknote recognition includes face value-oriented recognition and banknote authenticity identification. The general identification process of banknotes is to perform preprocessing such as tilt correction on the banknotes, then identify the currency type and face value of the banknotes, and then identify the authenticity of the banknotes according to the face value of the banknotes. The face value recognition of banknotes plays an important role in the identification of banknotes. If the face value is not recognized first, it is impossible to talk about the authenticity of banknotes. [0003] Since the banknote identification system requires real-time performance, it is generally required to complete the face value-oriented identification and authenticity ident...
