摘要

手指静脉识别是针对手指皮肤内部的静脉特征进行活体识别

具有非接触和安全性高等优点

但存在特征数量少的缺点;手指指节折痕位于皮肤表面

且具有稳定的生物学特性。因此

为解决单一模态手指静脉的可提取特征数量不足的缺点

设计了一种双模态生物特征图像采集系统

即针对手指相同位置

采集皮肤内部手指静脉和皮肤表面指节折痕2种不同类型图像。图像采集系统硬件主要包括USB202.0控制器、200万像素CMOS摄像头模组、可见光与红外光切换电路、微型步进电机驱动电路和I2C电路等。实验结果表明:该系统具有实时性

能够连续采集手指静脉和指节折痕2种清晰、稳定生物特征图像

为双模态生物特征识别系统提供了良好的软硬件基础平台。

Abstract

The advantages of finger vein are vivo identification

internal features

non-contact and high security

but features quantity of finger vein are insufficient

and finger crease is on the surface of finger skin

and it has some stable biological features.To solve the lack of finger vein feature quantity

a new dual-modal biometric image acquisition system is designed.The hardware system consists of USB 2.0 controller

CMOS camera module with two million pixels

visible and infrared light switch circuit

micro-stepping motor drive circuit

I2C circuit

and so on.Experimental results show that this system is real-time

continuously collect clear and stable finger vein image and the finger crease image and it provides good software and hardware platform for the dual-modal biometric system.
