Wenlou Yuan, Yuanhang Xu, Huan Liu, Dong F. Wang · Procedia Engineering · 2016
This paper presents a novel structural design of a biometric recognition sensor based on wrist vein, comprised by an array of NIR light source, a charge-coupled device (CCD) and a circle frame for a moving camera, to obtain the 3D vein image for security identification in mobile environment. An algorithm based on this structure was also proposed and explored preliminarily. It is believed what has been proposed can improve the accuracy by 3D vein image, reduce the influence of hand positon and pose in vein recognition and be more applicable to wearable devices.
