Finger vein and hand shape combined intelligent acquisition system and recognition method

The invention discloses a finger vein and hand shape combined intelligent acquisition and recognition method. A near-infrared acquisition unit acquires images of hand shapes and finger veins, extracts characteristic point information in the images and matches the characteristic point information with the stored characteristics to obtain a final judgment result. The method comprises the following step that the near-infrared acquisition unit acquires images of the finger veins and the images of finger shapes, and performs characteristic fusion on the two kinds of information. Two-finger acquisition increases information quantity of suspected biological characteristics (for one-finger acquisition, the vein images cannot be acquired due to difference of human bodies, and the information quantity is low and the recognition error probability is high if the hand shape is only acquired), and improves the positioning accuracy simultaneously. In addition, two-side lighting facilitates placementof fingers of users, whil
