Research And Design The Man-machine Interactive Interface Based On ARM Embedded System

In the information highly developed in today's society,how to quickly and accurately identify a person's identity,protection of information security is a key in today's information age must solve the social problems.Based on biometric identification technology,with its advantages of convenient,quick,safe and reliable as a future alternative keys,passwords,smart card,etc.The best choice for the traditional identification technology.In this paper,from the Angle of the rubber seals,in meet the application requirements of easy collection,easy to accept,from speech recognition and face recognition of two single-mode identification technology,this paper has carried on the man-machine interactive interface based on ARM embedded system research and design.This paper first to the development process of the voice recognition and face recognition and elaborates the present situation,and the system design principles and design goals are analyzed in detail.Then carries on the analysis of multiple biometric authentication system,combining with the system requirements select parallel authentication mode.The system hardware design part in order to complete the optimal design of the system and to the specific performance analysis has been done for the various functional modules,completed the construction of hardware platform and component selection.Including the overall design of the hardware,the microphone,camera module selection and schematic diagram design.The software design part from two aspects of the system software and application software to carry on the design.The system software design includes the construction of the embedded Linux system development environment,the kernel of the tailoring and each module driver to transplant.Application software part in complete Qt,OpenCV installed library transplantation on the basis of voice recognition and face recognition and interactive interface design.Target and architecture design first,secondly to design of the interface between voice and face recognition,has the voice and face information collection,processing,and identify functions,finally the whole system is transplanted into the ARM development board for testing.After testing,the hardware and software system running well,Can realize voice and face of biometric identification and reach the expected goal.
