Three-dimensional vein identification device applied to wearable device

Abstract

The invention, which belongs to the field of biometric features recognition, relates to a three-dimensional vein identification device applied to a wearable device. The three-dimensional vein identification device is composed of an intelligent control unit, an annular inner ring unit, an image sensor unit, a circular array type infrared light source unit, an annular outer ring unit and a drive control unit. The three-dimensional vein identification device has a novel structure. On the basis of a novel annular structure, the image sensor unit acquires information in a 360-degree angle during the vein image acquisition process; more vein information is obtained and identification becomes accurate; the reliability and robustness are high and an error rejection rate is low; the safety of identity information of the user is high; human-computer interaction is realized; the structure is simple; control becomes convenient; and the three-dimensional vein identification device is suitable for popularization.

Description

technical field [0001] The invention belongs to the field of biometric identification, in particular to a three-dimensional vein identification device applied to wearable devices. Background technique [0002] Vein recognition is a new biometric technology emerging in recent years. This technology uses the characteristics of human veins and blood vessels for identification, and has a very broad application prospect. Relevant medical research has proved that the distribution of veins in all people will be different, and once the distribution of veins in the human body is formed, it will basically not change over time. Therefore, veins have the characteristics of broadness, differentiation, persistence and repeatability that biometric identification should have. In addition, vein recognition also has many unique advantages that other biometric methods do not have, such as living body recognition, difficult to forge, non-contact recognition, etc., which makes vein recognition ...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides a three-dimensional vein recognition device applied to wearable devices to solve the following problems in the existing vein recognition technology: most of them are simple two-dimensional recognition, and the recognition results are easily affected by people's static postures and actions ; Fingers, wrists, and palms cannot be bent or deflected during the vein recognition process, which greatly damages the user experience and increases the false rejection rate; two-dimensional vein images are easy to forge, making security unsafe; based on binocular vision recognition The three-dimensional vein recognition device of the method can only obtain vein information within a certain angle. At the same time, it is very difficult to control because two cameras are required to shoot at the same time, and the device is very large and complex, and the cost is high, so it cannot be well applied to The popularity of wearable smart devices
