Abstract

A finger vein recognition device, the finger vein recognition module is connected with a camera and an infrared lamp in communication, a finger vein collection channel is provided in the box body, the end of the finger vein collection channel is an opening and is set on the surface of the box body, and a finger vein collection channel is provided at the head end for Lifting and lifting device, the head end of the finger vein collection channel is provided with a button to control the camera and infrared light, the channel gradually expands from the end of the finger vein collection channel to the head end, and the upper surface of the lifting device is provided with a touch switch for opening the lifting device. The middle section of the vein collection channel is provided with upper and lower two through holes, the upper through hole is provided with a camera, and the lower through hole is correspondingly provided with an infrared lamp, the infrared lamp is arranged on the circuit board, and the camera is connected to the finger vein recognition module for data. The advantages are as follows: firstly, when the finger is placed on the platform, the finger can be raised and lowered to make the finger straight, so as to facilitate better recognition of the finger vein; second, the three-dimensional recognition of the finger vein in all aspects of the whole finger improves the recognition efficiency and accuracy.

Description

technical field [0001] The invention relates to a finger vein recognition device. Background technique [0002] In the prior art, when the finger vein is used for identity authentication, the image features of the finger vein are obtained, which refer to the features that only exist in a living body. In this system, non-living fingers cannot obtain vein image features, so they cannot be identified, and thus cannot be faked. When using finger veins for identity authentication, the vein image features inside the finger are acquired instead of the image features on the surface of the finger. Therefore, there is no recognition obstacle due to damage, abrasion, dryness or too wet of the finger surface. Finger veins are used for identity authentication. When obtaining finger vein images, the finger does not need to touch the device, and the recognition can be completed with a light release. But the degree of bending of the finger will affect the efficiency of recognition. Con...
