Image-guided Rockets Detection System Design

This thesis designed an image-guided rocket detection system based on embedded systems. This detection system is on the basis of the developing of image-guided rocket and based on ARM9 microprocessor.This paper completed the total design and the basical functions of the detecting system. The selections of the microprocessor, embedded operating system and graphical user interfacc are discussed. This thesis also completed hardware design of the detecting system based on the ARM9 processor of AT91SAM9261. The core board which is composed of SDRAM, AT91SAM9261, and Flash circuit and the functionalbottom board composed of video image acquisition and processing, Ethernet, AD/DA conversion circuit are made.On the basis of the hardware platform of detection system, this paper constructed an embedded-based software platform, including the setuping of development environment and the ompiling and transplanting of boot loader, kernel, file system, etc.Finally, this paper completed the design of embedded Linux device drive and the Qt4 application program based on the hardware and software platform of the detection system. The basic detection functions of the system which is designed in the beginning are realized.
