Example Embodiment

[0030] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0031] Such as figure 1 As shown, an electronic lock unlocking method based on finger vein recognition includes the following steps:

[0032] S1. Obtain fingerprint feature images of the finger. The fingerprint feature images include fingerprint images, fluoroscopic vein images, and epidermal vein images.

[0033] The step S1 includes the following sub-steps:

[0034] S11. Put the finger in the image acquisition area, turn on the light source, and control the image acquisition device to rotate around the finger; the light source includes the first near-infrared LED light group installed on the opposite side of the image acquisition device and is installed on the image acquisition device obliquely The second near-infrared LED light group around.

[0035] S12. Th...

Abstract

The invention discloses an electronic lock unlocking method based on finger vein recognition. The electronic lock unlocking method comprises the following steps that S1. fingerprint feature images of fingers are acquired, and the fingerprint feature images includes an image, a perspective vein image and a cuticle vein image; S2. the feature data of the fingerprint image, the perspective vein image and the cuticle vein image in the step S1 are extracted; S3. the feature data acquired in the step S2 are compared with pre-stored sample feature data, and the process jumps to step S4 when the two sets of data are consistent; S4. whether the fingers are living bodies is judged, and an authorization code is acquired if the fingers are living bodies; S5. an unlocking logic signal is analyzed according to the authorization code; and S6. unlocking is performed according to the unlocking logic signal. Unlocking is realized through verification of the fingerprint image, the perspective vein image and the cuticle vein image of a user so as to be secure and convenient.

Description

technical field [0001] The invention relates to the technical field of electronic locks, in particular to an electronic lock unlocking method based on finger vein recognition. Background technique [0002] Biometric authentication technology is now widely recognized and has been certified by national certification bodies and is widely used in various industries. Due to its lifelong invariance, uniqueness and convenience, fingerprint has almost become synonymous with biometric identification. Fingerprints are the uneven lines on the skin on the front of the end of a person's fingers. The lines are arranged regularly to form different grain types. The starting point, ending point, joint point and bifurcation point of the ridge line are called the minutiae feature points of the fingerprint. However, the existing fingerprint recognition has the following defects: (1) Some people or certain groups have few fingerprint features, which makes it difficult to image; Fingerprint i...
