| With the fast development of modern information age, the information to beprocessed is skyrocketing immensely. The researches and applications of imageprocessing catch great attentions from researchers all over the world. In recent years,the development of DSP technology has put the theory achievement of digital signalprocessing field into practical systems, and pushed the progress of new theory andapplication. At the same time, it plays an important role in the field of imageprocessing.With the development of infrared imaging technology and infrared focal planearray (IRFPA) solid image detectors, IRFPA is widely used in various imaging systemin the military, industrial and commercial fields. Typical applications include missileguidance, aerial survey, infrared hunting and tracing system, custom suppresssmuggling, salvage equipment and forest fire control etc. The requirements of thequality of infrared imaging is becoming higher and higher.In this dissertation, the software design of infrared image pre-processing systembased on TMS320C6203B is studied. According to the thorough analysis ofperformance and characteristics of TMS320C6203B and characteristics of infraredimaging, the software implementation scheme of infrared image pre-processingsystem based on TMS320C6203B is put forward. After analyzing non-uniformity ofinfrared image, an improved algorithm called one-plus-two point correction algorithmis proposed. Firstly, the system structure and the software and hardware constitute issimply introduced. Then the design data transmission by DMA is expounded. Theanalysis and implementation of key algorithms are introduced in detail. The design ofinterrupt is studied. The design of interface is analyzed. Meanwhile, the design ofserial port is discussed. According to the practical measurement of this system, theperformance of both hardware and software all meet with such requirements asstability, reliability and real time etc. And functionally, it is general to some extent. |
