Title: THREE-DIMENSIONAL FINGER VEIN RECOGNITION METHOD AND SYSTEM
Abstract:
A three-dimensional finger vein recognition method and system, comprising the following steps: three cameras taking finger vein images from three angles to obtain three images; constructing a three-dimensional finger model according to finger contour lines; mapping two-dimensional image textures photographed by the three cameras into the three-dimensional finger model, respectively performing different processes on an overlapping region and a non-overlapping region; obtaining a three-dimensional finger vein image; and finally, performing feature extraction and matching on the three-dimensional finger vein image, to complete recognition. The method can acquire a better finger vein recognition effect, and has a higher robustness for a plurality of postures, such as finger rotation and inclination.
