Embodiment Construction

[0023] 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.

[0024] 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

The invention provides a vein recognition device for recognizing finger veins. The vein recognition device comprises a reflecting part and an infrared camera; the reflecting part is equipped with a reflecting surface; the lights irradiates the finger veins and is transmitted through the finger veins to form an incident beam, the incident beam is incident into the reflecting surface to be reflected to form an imaging beam, and the imaging beam is incident into the infrared camera to image the finger veins. According to the vein recognition device, the incident beam and the imaging beam are spread in different directions, thus that the light source, the reflecting part and the infrared camera are accumulated in one direction can be avoided, and the thickness of the vein recognition device can be reduced. The invention further provides a mobile terminal system and a mobile terminal thereof.

Description

technical field [0001] The invention relates to a biometric identification device, in particular to a mobile terminal system and its mobile terminal, and a vein identification device. 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 a...
