The Design Of High Speed Image Acquisition And Processing Based On DSP

With the rapid development of computer, image processing becomes more and more convenient, which becomes a very important and basal technic in the modernistic communication processing field. At present, image processing, has a patten of camera to frame to computer. It's disadvantage is low processing speed and accessible to entironment. The embedded image acquisition and processing system proposed by the dissertation can deal with long-distance and real-time data independently.In the paper, the real-time mark points in the process of test driver tested and processed, based on the test and dynamic adjust of three dimension dynamic parameter ,such as tilt angle, pendulum center, motion track, motion speed, accelerated speed, in the process of the rocket engine cold or heat test-drive. After known the application and develop status, aimed at the requirement of the high speed and real-time, a preliminary plan of embedded real-time image acquisition and processor system is put forward based on the DSP&FPGA.In the dissertation, the whole hard-system is designed and the software aimed to process the image is programmed. TMS320C6416T from TI is used as image processor, and EP1C6 from ALTERA is used as time sequence controller.In the design of the hardware, except the choose of the key chips, the design of the interface of camera and the embedded system, DSP and FPGA, DSP external memory, DSP external serial port, DSP electric source are included. In the design of software, programme is designed for the test of the system feasibility. The key programme is given, for example the programme of how to set-up the cmd file. The boot loader programme is introduced stressly, including the boot approach.The system is specialized in two aspects: one is the high-speed of the devices and the code-optimization, the other lies in lower consumption and better cost-effective.
