Embodiment Construction

[0049] 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.

[0050] refer to figure 1 , figure 1 It is a schematic flowchart of a method for detecting a new version of RMB provided by an embodiment of the present invention.

[0051] Such as figure 1 As shown, the method for detecting the new version of RMB includes:

[0052] Step 101, intercepting the area to be identified in the new version of RMB to be detected, the area to be identified includes the area of ​​the second security line feature;

[0053] Specifically, such...

Abstract

The invention discloses a method and apparatus for checking a new-edition RMB banknote. The method comprises the steps of intercepting an area to be checked in a new-edition RMB banknote to be checked, and the area to be checked containing a second safety line feature area, conducting binary processing for the second safety line feature area, calculating the left and right boundaries according to a second safety line feature, matching a second safety line feature within a scope defined by left and right boundaries with a template, and determining the new-edition RMB banknote is authentic if the second safety line feature within a scope defined by left and right boundaries matches with the template. The method is low in algorithm complexity, and the time efficiency is high for the feature template matching algorithm. Selection of a binary threshold is set according to the proportion actually occupied by a black block, the binary effect is good, and the interference of noise is unlikely to occur. The method for checking black-and-white characteristics based on template matching ensures high accuracy.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of banknote identification, and in particular to a method and device for detecting a new version of RMB. 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 authent...
