摘　　要：水印条码是欧元引进的新防伪点,它携带欧元纸币的特定信息,因此研究出一套准确,快速识别欧元防伪条码的检测方法是有其实际意义和应用前景。本文采用TMS320VC5409数字信号处理器、MSP430单片机为主要器件,基于实现对欧元水印条码进行有效、准确、快速识别的目的,设计一套识别系统。并且对做出的系统电路进行实验研究,对采集到的不同纸币的水印条码曲线进行分析,并将新的面值为50欧元纸币的水印条码采集曲线与其他纸币的采集曲线进行分析比较,计算其相关度。最后结合水印的自身特点,水印条码的退化现象,以及实验条件等方面分析相关度出现较低现象的原因。最后对实验结果的误差进行分析,提出下一步研究的重点。Watermark bars are one of the new anti-counterfeit technologies applied by Euros.Because they carry Euros' special information so it is promising and practical to make research on the method to detect watermark bars quickly and accurately.This essay introduces our research on the detection system of watermark bars in Euros.The work use DSP and MCU as the main part to identify counterfeit notes efficiently and fleetly by the detection of watermark bars.We have made experiments by the detection system and get the signals and output.Made analyze of the results and experiment curves of watermark bars of different Euros of different value.And computed the correlation coefficient of watermark bars' curve and bring the advanced plan.
