Two-finger vein verification device and method

The invention provides a finger vein verification device, which comprises a shell, a light source and an image collector. The upper surface of the shell is provided with double finger grooves; opticalfilters are arranged at the bottoms of the two grooves of the double-finger grooves, and the passing frequency of the optical filters is matched with the light frequency of the light source; the image collector is fixedly arranged in the shell and is used for collecting images of the double finger grooves; the light source is arranged on the upper surface of the shell, and the light angle of thelight source is right opposite to the double-finger grooves. The authentication accuracy can be effectively improved, and the false identification rate is reduced. Meanwhile, when the device is used,two adjacent fingers are put in at the same time, so that the fingers can be kept horizontal, the consistency degree of the finger vein authentication template and a registered template is improved, and the problem of verificat
