Robot Vision System Design Based On Embedded System

With the development of computer technology, machine vision has been successfully used in industry, agriculture,national defence and so on. According to the environment on which it is used, the machine vision can be classified as PC-based system and PLC-based system. Both of them are somewhat expensive, complicated in hardware and software, and large in volume, therefore their application is limited.The research is chosen at the connection of machine vision and embedded system,aimed at combining them and designing machine vision system based on embedded system. The result proved that the trying is successful. A machine vision algorithm based on embedded system is brought forward through recalling some algorithms, on the basis of which a hardware and a software system are built. A lot of simulating and experiments proved that the result is good and the objective attained.The dissertation includes five chapters. In the first chapter, machine vision,embedded system and robot are introduced briefly, and then the objective and content of the research work presented. In the second chapter,ARM and DSP were introduced briefly,then RTOS uc/OS-Ⅱwas referred.In the third chapter, the hardware/software system is designed according to the requirements presented in first chapter and the technology of hardware designing which is popular presently and introduce Emedded operation system porting.The fourth chapter is contributed to the research of algorithm,bring forward two navigation methods applicable to this kind of embedded robot’s vision system.In last chapter, some experiment results on the hardware, algorithm and software have been discussed and make a hope.
