Problems solved by technology

However, after a long period of circulation of banknotes, there are often stains on the serial number, which makes it difficult for banknote counters to identify
In addition, when the banknote counter scans the serial number, the numbers or letters in the serial number may be distorted due to the angle relationship, making it difficult for the banknote counter to recognize

Abstract

The invention provides a method for identifying a serial number on a bill. The method includes the steps that a current identification serial number can be generated from the serial number on the bill according to a binaryzation algorithm, a connected component labeling algorithm, a linear classi er algorithm and a tangent distance algorithm, and the current identification serial number is checked through the other serial number (if the other serial number exists) on the bill and / or a check sum valve corresponding to the serial number on the bill. Thus, the identification accuracy of the serial number on the bill can be effectively improved.

Description

technical field [0001] The invention relates to a banknote serial number identification method, in particular to a paper banknote serial number identification method that can effectively improve the identification accuracy of the serial number on the banknote. Background technique [0002] The existing bill counter is an electronic device that automatically counts the number of banknotes. Due to the large scale of cash circulation and the heavy cash handling work at the bank teller counter, the bill counter has become an indispensable device. Generally speaking, most banknote counters have the functions of counting and identifying counterfeit banknotes. In addition, because the serial number on banknotes is encoded by special rules, it can be used as an application to track the flow of banknotes, and some banknote counters also have a serial number identification function. However, after a long period of circulation of banknotes, there are often stains on the serial numbers...
