Design Of Embedded Multi-modal Biometrics's Identify Based On ARM

Biometric ideniification refers to an identification technique of a Person, based on his/her inherent biologic charaeteristic by computer.Due to the uniqueness and in variability of biologic charaeteristic,the biometric identification is more attractive,compared with traditional methods such as password and ID certificate.However,Most of traditional high performance automation biometric identification system is based on PC online application.Nowadays,because of the wide use of the automation ideniification system,it is required to be easier to carry and use.Therefore embedded biometric identification system becomes a hot topic. Such a system can be fulfilled as embedded technology grows rapidly.Abiometric identification system is mainly made up of the general module which consists of control system and the distinct module which consists of the image-collected equipment and recognition algorithn.This thesis focus on the interface of the general module and the distinct module so that the embedded system we design can work well.We design the core circuit,expand circuit,switching circuit,and transplant the real-time OS Linux to the hardware,we also complete the drivers of many modules in the develop circuit,and compose the program of Multi-camera's cutover.In addition to this,we solve the light-atuomatic-control equipment.
