Embodiment Construction

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

A vein identification device is used to identify finger veins. The vein identification device includes a light source, a reflector and an infrared camera. The reflector is arranged on one side of the light source, the infrared camera is arranged on the side of the reflector away from the light source, and the infrared camera is arranged opposite to the light source. The light from the light source is emitted to form a projection beam, which is projected on the finger vein and reflected by the finger vein to form an incident beam. The incident beam is incident on the reflective surface, and the incident beam is reflected by the reflective surface to form an imaging beam. Finger veins are imaged. The incident beam of the above-mentioned vein identification device is different from the propagation direction of the imaging beam, so that the accumulation of light sources, reflectors and infrared cameras in one direction can be avoided, and the thickness of the vein identification device can be reduced. A mobile terminal is also provided.

Description

technical field [0001] The invention relates to a biometric identification device, in particular to a mobile terminal and a vein identification device thereof. Background technique [0002] Vein recognition is a kind of biometrics. The vein recognition system first obtains the personal vein distribution map through the vein recognition device, extracts the characteristic value from the vein distribution map according to the special comparison algorithm, obtains the images of the finger, palm and back of the hand vein through the infrared camera, and stores the digital image of the vein in the computer system In , the feature values ​​are stored. When comparing veins, take vein images in real time, extract feature values, use advanced filtering, image binarization, and thinning methods to extract features from digital images, compare with vein feature values ​​stored in the host, and use complex matching algorithms to match The vein characteristics are matched to identify t...
