摘要
纸币的防伪与检伪水平关系着国家的金融安全,研究模式识别技术在人民币检伪中的应用,是为了探究如何不断提高人民币真伪判定的准确率,从而为相关的设备开发奠定基础。首先对模式识别技术做了简要总结。从人民币宽度检测和磁性信号检测两个方面,对模式识别技术在人民币检伪中的具体应用进行讨论。针对货币检测过程中的信号变化,以宽度检测和磁性信号的检测为实例,对信号的采集、信号的处理、真伪的判断开展了研究。相关研究结果可以应用在线性CCD信号的处理和分析之中。为货币的真伪检测方法与判定策略提供了参考实例。
Anti false and false detecting level of paper currency relates with the country＇s financial security. Its pattern recognition technology in false detecting of RMB, /s to explore how to continuously improve the accurate rate of RMB authenticity, so as to lay the foundation for the development of related equipment. It gives a brief summary of the pattern recognition technology. It discussed the application of the pattern recognition technology in RMB identification from two aspects： the width detection and the mognetic signal detection of RMB. It took the width detection and the magnetic signal detection as examples, studying the ways of signal acquisition and processing,and the judgment of results. Related research results can be used in the signal processing and analysis of CCD. It provides application examples for the detection of currency.
