The Study Of Real-Time Image Processing Based On DSP

Along with the development of the science and technology, the system that automatically target recognition(ATR) has become an extremely important part for the present and the future weapon system in military field. Among them weak signal target real-time examination, identify, catching and trace that has become the main study direction in the domestic and international range for photoelectrical measure equipments. In this theses, a method of real-time image measurement system based on DSP that is used to process weak signal is introduced. The high speed digital signal processor TMS320C6202 is a kernel device in this system, combined with FPGA. This system not only meet the real time request but also have the function to automatically identify and measure target.This theses mostly studied a series of arithmetic of image preprocessing, image segmentation and image matching for image data, referring to advance image processing technique overseas at present. Regarding the real-time image measurement system as the tool for debugging, it finds appropriate arithmetic to process real-time image and applies them to actual hardware equipment. The system has higher precision and more real-timely. It solved target detection problem of real-time image processing system in 4% contrast. This can make equipments away from dangerous zone. And perform full trajectory measurement and provide correct guiding data for other equipments. It pushes forward the defensibility of our country.
