Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] The preparatory work for the implementation of the method of the present invention is to simultaneously collect images of banknotes online when the banknote detector is turned on, aiming at the consistent direction of banknotes here, all of the collected images are at the lower left corner of the banknotes, and the control system processes the collected images in time , to complete the online automatic identification of the number, the specific implementation steps are as follows:

[0022] Step 1. Initial positioning of the number area on the banknote:

[0023] Such as figure 1 , it can be seen that the number area on the banknote only occupies a very small part of the whole banknote, and the rest is irrelevant information. Therefore, in order to reduce the time spent on system recognition, it is best to perform binary processing on t...

Abstract

The invention discloses a paper currency number identification method based on a currency detector. A COMS (Complementary Metal Oxide Semiconductor) sensor is firstly installed on the currency detector and connected with a control system. The identification method comprises the following steps of: firstly, preliminarily locating a number region on paper currency; secondly, dividing the paper currency numbers which comprises the steps of: preliminarily dividing ten characters, precisely dividing the ten characters and scaling the characters; and thirdly, character identification which comprises the steps of calculating a gridding feature matrix of the divided characters, making a template matrix and identifying the characters by utilizing a matrix template matching identification method. The method mainly aims to Renminbi of 2005 version, adopts vision inspection of a computer as important technical means, utilizes a digital image processing technology, integrates image acquistion, number locating, number dividing and character identification into a whole, finally identifies 26 letters from A to Z and ten numbers from 0 to 9 and realizes the online automatic identification of the paper currency numbers.

Description

technical field [0001] The invention belongs to the technical field of automatic identification, and relates to a banknote number identification method based on a banknote detector. Background technique [0002] As an important ticket, banknotes are all printed with serial numbers, and their numbers are unique, so they can be used as an identification to distinguish banknotes. As the current production of counterfeit banknotes is becoming more and more sophisticated, but because of its fixed number, identifying counterfeit banknotes through banknote numbers is also a development direction for future banknote detectors. In today's advanced technology, the theoretical knowledge, technology and hardware technology required for automatic number detection are very mature. Banknote number recognition technology has been relatively mature especially in Britain, Japan, Germany and other western developed countries, and corresponding products have been widely used in banking busines...
