Embedded iris identification device based on TMS320F28335

Abstract

The invention discloses an embedded iris identification device based on TMS320F28335, characterized by comprising a power module, an image acquisition module, an image processing module, a storage module, a human-machine interaction module and a data transmission module, wherein the image processing module is a core to the device and is connected with the power module, the image acquisition module, the storage module, the human-machine interaction module and the data transmission module. Iris images are acquired through OV7141; DSP (digital signal processor) TMS320F28335 is used to perform characteristic value extraction on images before registration or matching, and processing and displaying are finally performed. The advantages of the iris recognition technique, such as high uniqueness,high stability, high anti-counterfeiting property and zero invasion are utilized; the embedded iris identification device based on TMS320F28335 has the advantages of good extensibility, high working efficiency, low power consumption, good simplicity, safety, reliability and convenience and the like.

Description

technical field [0001] The invention relates to an identification device, in particular to an embedded iris identification device based on TMS320F28335. technical background [0002] As computers, ATMs, mobile phones, access control systems and other electronic devices continue to enter people's daily lives, it is becoming more and more urgent for personal security and convenient identity verification technology. The existing systems based on smart cards, ID numbers and passwords can only hover between security and convenience, and real security has never been realized. In order to obtain higher security, the complexity of the password must be increased. However, there are too many passwords around us, which are easy to forget, and using the same password leads to reduced security and increased risks. The iris is an open part of the human body. It is easy to monitor remotely through machine vision. Because of its physiological characteristics, the iris will not be forgotte...
