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...
