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.
