Embodiment Construction

[0077] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0078] Such as figure 1 As shown, a multi-modal recognition device based on face, fingerprint and finger vein information includes: a housing 1, which is provided with a finger insertion hole 7; the inside of the housing 1 includes a light source module, Wherein comprise several near-infrared light irradiation sources 4, and cover the frosted glass scattering plate on its surface; And be arranged on the first camera 31 above the light source module; A circuit module 6, the second camera 32 is covered with an infrared filter 2, and both the first camera 31 and the second camera 32 are near-infrared sensitive cameras; and the fingerprint collection module 5 on the opposite side of the finger insertion hole 7 .

[0079] The housing 1 is made of light and opaque material such as black acrylic board.

[0080] The near-infrared light irradiation source 4 i...

Abstract

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.

Description

technical field [0001] The invention relates to a multi-modal recognition device and method based on human face, fingerprint and finger vein features. Background technique [0002] Biometrics is a new identity authentication technology. In real life, everyone has unique biological characteristics that are different from other people. With the development of computer technology, people can extract their own biometric information, such as face, fingerprint, finger vein, iris, voiceprint, etc. This technology that relies on people's physical characteristics for identification is called biometric technology. [0003] Identification using only a single biometric feature (single-modal biometric feature) is easy to be forged and deceived. For example, a single fingerprint picture is easy to be forged, imitated and stolen, and fingerprint recognition was originally used in the criminal field to make some users exist. Resisting psychology, and the single fingerprint (finger vein, ...
