基于伪双目立体成像自动识别新技术

New Auto Identification Technology on Paper Currency Using Pseudo Binocular Stereo Imaging

现有的人民币伪钞等打印信息的识别技术主要是对钞票上的安全线、水印、磁性油墨、荧光油墨等物理特性进行识别。随着伪造技术的发展,特别是随着HD90、TJ55、AZ88、WL15、YX86等仿冒手段不断提高的伪钞的出现,对人民币的鉴伪技术提出了一种更高的要求。提出了一种基于人民币凹版印刷特性,利用普通平板扫描仪进行钞票的伪双目立体成像,对其浮雕纹理进行计算机自动识别,进而实现真、伪钞鉴别的新方法。通过实验验证了该方法的正确性和实用性。给出了基于此方法的伪双目立体成像扫描仪的快速验钞机原型设计。

The current paper money identification techniques are based on safe-line,watermark,magnetic inks,fluorescence ink,etc.Alone with the development of fake technology,the anti-counterfeit technology needs new ways.This paper presented a brand-new anti-counterfeit method,which is based on the intaglio character of the paper currency,using a common flatbed scanner to achieve the pseudo binocular stereo image of the paper currency,and recognizing the relief texture to identify the real or fake currency.Furthermore,we also brought out a pseudo binocular stereo scanner prototype,which is a better currency detector with high efficiency.With the benefits of this scanner,our method can be applied automatically and is much faster.
