The invention discloses a multimode recognition device and a method based on features of a face,
fingerprint and finger
vein. The multimode recognition device based on features of the face, the
fingerprint and the finger
vein is prepared and started; after the intensity of a
light source is stabilized, the original image of the face is acquired by a first camera, the original finger image of the
vein of an extended finger is acquired by a second camera, and a
fingerprint module acquires the original
fingerprint image; the
living body image obtained through judgment is subjected to denoising and
image enhancement processing, and whether the face image, the
fingerprint image and the finger vein image are all living bodies are judged; if a dummy body exists in the images, the dummy body image is eliminated; features of the obtained and judged
living body images are extracted respectively; the extracted features are fused in a feature layer to obtain new features; the new features obtained through fusion are used to
train a classifier; and a training feature
library is generated, and the training feature
library is used to carry out multimode identity
authentication on a test person. The problems that destruction and forgery are likely to happen and the recognition success rate is low and the recognition is instable in the case of single living thing recognition can be solved.
