Finger vein recognition system and method

A finger vein recognition system, comprising:

• a image catching module for catching a finger vein image;
• a image preprocess module, connected to the image catching module, for preprocessing the finger vein image in accordance with a predetermined procedure;
• a feature points calculating module, connected to the image preprocess module, for catching a plurality of feature points from the preprocessed finger vein image, and calculating a set of distances among the plurality of feature points;
• a feature database for pre-storing a set of feature data;
• a first comparing module, connected to the feature points calculating module and the feature database, for comparing the set of distances and generating a compared result of feature point distances;
• and
• a second comparing module, connected to the image preprocess module, the feature database and the first comparing module, for catching a set of vein shape and comparing the set of vein shape with the feature database for generating a compared result of shape similarity;
• wherein the second comparing module combines the compared result of feature point distances and the compared result of shape similarity for generating a recognized result of the finger vein.
