This paper reports a new wrist vein biometric passive recognition sensor with preliminary verification based on a shuttle roller coaster structure. This sensor can obtain the vein images around the wrist to construct a 3D vein model for vein recognition. The experiment has proved that this sensor provide more information for the 3D vein modeling, which paves the way for the following design. It is...
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...
