The Design And Implement Of Eye Tracking Based On Embedded Linux

Eye localization is a hotspot research in the field of image processing and recognition problems,both in the field of human-computer interaction and in the aspect of behavior analysis has very important value and significance.And the development of the computer is very fast,embedded technology is becoming a hot spot of the information industry.It is based on ARM platform,uses the Linux operating system.Eye view real-time positioning system was designed and implemented.1.The vision detection are introduced in detail the research status of application and the development of the future,compared to the line of sight of the existing test methods.2.On the hardware system and software development for this article.Mainly includes the ARM as the core of hardware system,the transplantation of Linux system with cross compile;Myeclipse RXTX using Java used serial communication.3.In detail in this paper,the design of the overall framework and specific function module,and key technologies were introduced in this article.4.Detailed introduces the vision detection algorithm based on image processing method.Some of the basic algorithm was improved.Algorithm is improved to improve positioning accuracy and precision,so as to achieve real-time performance5.The system test To test the design of the whole system to evaluate positioning accuracy and precision.Analysis system still existing problems,propose solutions and the prospect of the future.The whole system with ARM board as hardware platform,software and hardware together.Hardware to guxtim as the control core,designed the peripheral expansion board,Linux system running.Software,mainly use the Debian/Linux operating system of Vim,GCC to compile debugging.Final terminal using Java write visual interface,the line of sight control reading,achieve the final result display.
