| 摘 要： | 针对指静脉身份认证需求,以手指静脉图像采集系统作为研究对象,设计了基于单侧光源与反射镜面相结合红外光源可调控的指静脉图像采集系统。研究了LED光源位置与角度对静脉图像质量的影响,提出了基于图像质量评价的指静脉认证方法,并运用实测方法进行了验证。实验结果表明:可以得到与传统正面光源采集同等质量的静脉图像,具有更高的认证通过率,达到98.8%,并更易于用户使用。

| Abstract: | Aiming at finger-vein identity authentication requirements, a near-infrared light source controllable finger-vein image acquisition system is designed based on single light source and reflection mirror. The impact of LED light source position and angle on vein image quality is studied, finger-vein authentication method based on image quality assessment,is proposed and verified by actual measurement method. Experimental results show that the proposed vein image acquisition system can obtain vein image of equal quality with traditional front light source acquisition has higher authentication passing rate of 98.8 %, and easy to use for user. |
