Problems solved by technology

However, the existing finger vein collection devices are relatively large in size, and the automatic exposure of some devices will be excessive or insufficient, and some devices do not even have the function of automatic exposure, and the clarity of the vein image is relatively poor.
To avoid the shortcomings of single biometric identification, it is required to use multiple biometric identification to improve the authentication system.

Embodiment Construction

[0043] The present invention will be described below in combination with specific embodiments and with reference to the accompanying drawings.

[0044] a kind of like Figure 1~5 The fingerprint and vein collection device shown includes a housing and a fingerprint collector arranged in the housing. The fingerprint collector includes an optical single-fingerprint imaging module arranged in the housing, and a backlight unit 18 for fingerprint collection. The imaging module includes a triangular cylindrical prism 1 arranged along the optical path, an imaging component, an image acquisition unit for fingerprint acquisition and a light source,

[0045] The fingerprint image receiving surface of the image acquisition unit for fingerprint collection is provided with a CMOS sensor 14 for collection of fingerprints, which converts the received single finger fingerprint image into an electrical signal output. The bottom of the shaped prism 1 includes a main control chip 12, a storage u...

Abstract

The invention discloses a device for collecting fingerprints and veins, which comprises a shell, a fingerprint collector and a finger vein image collector, wherein a finger hole is arranged at the middle part of the shell; the position relative to the finger hole in the shell is a finger vein collection window which is at the same horizontal plane with a finger collection surface; the finger vein image collector comprises a circuit control module, an optical system, a CMOS (complementary metal-oxide-semiconductor transistor) sensor and a backlight unit, wherein the CMOS sensor is arranged below the shell and used for collecting the veins, and the backlight unit is arranged above the shell and used for collecting the veins; the circuit control module is a circuit control module of the fingerprint collector; and the optical system comprises an infrared optical filter, a planar reflector used for collecting the veins and a plano-convex lens used for collecting the veins; Modular design is adopted in the device for collecting fingerprints and veins; fingerprint identification and vein identification are integrated; and the device for collecting fingerprints and veins has anti-counterfeiting function, is strong in safety and high in identification precision, cannot be lost and stolen, has no burden for remembering the password, and can be combined with a computer to be used so as to finish finger vein collection, finger vein comparison of a user and abnormal alarm and can control the output of signals.

Description

technical field [0001] The invention relates to a method or device for biometric identification using electronic circuits, in particular to a fingerprint and vein collection device. Background technique [0002] Fingerprint recognition is based on the outer layer characteristics of human fingerprints, and it is difficult to prevent counterfeiting by related personnel forging fingerprints on the residual smooth surface, which has potential security risks. Finger veins are located under the skin of the human body and are almost unforgeable. Vein recognition, as an emerging biometric technology, has very high security, will not be lost, will not be stolen, and has no memory password burden. However, the existing finger vein collection devices are relatively large in size, and the automatic exposure of some devices may be excessive or insufficient, and some devices do not even have the function of automatic exposure, and the definition of vein images is relatively poor. To avoi...
