摘要: 针对二维平面指纹图像防伪性不高的问题,设计了一种由1个摄像单元和2个平面镜构成的单目多视角立体机器视觉装置,通过该视觉装置从3个不同视角来获取手指的指纹图像;然后对不同视角的指纹图像进行三维融合拼接,得到一幅便于识别的三维指纹图像;最后对三维指纹图像进行指纹图像增强和识别等处理。实验结果表明,基于单目多视角立体机器视觉的装置能保证一次性获得多个视角的指纹图像,融合拼接后的三维指纹图像提高了指纹识别的防伪能力,装置具有很高的性价比。

Abstract: For the low security problem of 2D fingerprint image,a monocular multi-view device which consists of one camera and two flat mirrors was designed to obtain three fingerprint images from three different perspectives.Then three different perspectives of fingerprint images are fused,and a 3D fingerprint image with large effective area can be got.Finally image enhancement and recognition are used in 3D fingerprint image.The experimental results show that the design of monocular multi-view device can guarantee a one-time access to multiple perspectives of fingerprint image,and the result image enhances the security of fingerprint recognition.
