基于伪双目立体成像自动识别新技术

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。

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

The current paper money identification techniques arc based on safcline, 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.
