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 multi-modal recognition device and method based on human face, fingerprint and finger vein features; preparation and start-up of the multi-modal recognition device based on human face, fingerprint and finger vein features; after the intensity of the light source is stabilized, the first The camera collects the original image of the face, the second camera collects the original image of the finger inserted into the vein of the finger, and the fingerprint module collects the original image of the fingerprint; denoising and image enhancement processing are performed on the judged living image to judge the obtained human Whether the face, fingerprint and finger vein images are all live; if there is a prosthesis in the image, delete the prosthetic image; extract and judge the features of the living image separately; fuse the extracted features in the feature layer to obtain new features; use fusion The obtained new features train the classifier; generate a training feature library, and use the training feature library to perform multi-modal identity authentication for testers. Solve the problem that single biometric identification is vulnerable to damage and forgery, and the success rate of identification is low and unstable.

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, ...
