Abstract

The invention provides a multi-sample feature-based palm vein recognition method. The method comprises the following steps: acquiring a registered palm vein image and a to-be-detected palm vein image through a palm vein acquisition device; performing preprocessing and feature extraction on a registered palm vein image and a to-be-detected palm vein image acquired in the step to obtain a registered palm vein feature image and a to-be-detected palm vein feature image; performing feature fusion matching on a registered palm vein feature image and a to-be-detected palm vein feature image through a Fisher criterion to obtain a matching score of the fused registered palm vein feature image and the to-be-detected palm vein feature image; recognizing a to-be-detected palm vein image through the matching score obtained in the step; according to the invention, the direction of the palm projection lamp is adjusted in multiple directions to acquire multiple groups of data to recognize the palm vein, so that the problem of difficulty in palm vein recognition caused by different palm placement positions and angles and different personal postures is avoided.

Description

technical field [0001] The invention relates to the technical field of biological identification, in particular to a palm vein identification method based on multi-sample features. Background technique [0002] Palm vein recognition is a kind of vein recognition, which belongs to biometrics and belongs to internal physiological characteristics, and will not wear out; veins are blood vessels that lead blood back to the heart, starting from capillaries and ending at the atrium, superficial veins can be seen under the skin; Vein, as the name implies, is the vein in the palm. Palm vein recognition is a kind of vein recognition, which belongs to biometrics. The palm vein recognition system first obtains the personal palm vein distribution map through the vein recognition device, and extracts from the palm vein distribution map according to the special comparison algorithm. The eigenvalues ​​are obtained by the near-infrared CCD camera to obtain images of veins in the fingers, pal...
