Sliding type self-adaptive finger vein recognition device and method

Abstract

The invention discloses a sliding type self-adaptive finger vein recognition device which comprises an installation system, the installation system comprises an installation wall, and the installationwall comprises a control center, and an infrared detection module, a heart rate detection module, a slip sheet starting module, a voice broadcast module, a vein acquisition module and an annular motor control module which are electrically connected with the control center. Two cameras are adopted for vein collection, so that the collected finger vein veins are more accurate, an optical heart ratesensor can be used for effectively preventing people with other worries from cracking equipment by using false vein membrane materials, the safety of the device is improved, and the cameras can be rotated by using an annular motor control panel. Finger vein information is collected in a multi-dimensional mode to obtain a high-quality image, and the reliability of the device is improved. Accordingto the device, the contact pieces and the corresponding mounting contact pieces are arranged in the mounting wall, so that opening and closing of related detection can be controlled, and resources can be effectively saved.

Description

Technical field[0001]The invention relates to the technical field of finger veins, in particular to a sliding type adaptive finger vein recognition device and method.Background technique[0002]Finger vein recognition is a type of vein recognition. Near-infrared light is used to illuminate the finger, and the light is transmitted to the CCD camera through a filter to obtain an image of individual finger vein distribution. A special algorithm is used to extract the feature value of the finger vein on the finger vein distribution map, the image of the finger vein and the acquired feature value information are stored in the computer, and finally the image feature matching algorithm is used for authentication and recognition.[0003]The existing finger vein recognition device has poor security. A single camera captures a flat image. If someone with ulterior motives uses a transparent film or other thinner film material that can be penetrated by an infrared light, and use the corresponding f...

Problems solved by technology

[0004] The purpose of the present invention is to solve the low security caused by the inability of the existing finger vein recognition device to identify true and false finger vein information, and the inability of the existing finger vein device to solve the problem that different groups of people have different needs when collecting finger vein information, which leads to the inability to obtain finger vein information. A sliding self-adaptive finger vein recognition device and method is proposed due to the shortcomings of high-quality images. This invention improves the safety and reliability of the finger vein recognition device, and achieves convenient control and effective energy saving through sliding control.
