Infrared Image Target Identification And Tracking Technology And Its Dsp Implementation

The bicolor IR rosette scan guidance is the key technology of a terminal guidance system, and the important research subject of infrared imaging guidance0 It adopts the advantages of infrared and imaging guidance0 Instead of 1 pulse recognition, this technology uses image recognition to improve the resolution ratio and recognition distance 0 Additionally, being its advantages of lower cost, better portability, shooting facility, and good tracking performance, it is valuable and significant0 Based on the analysis of rosette scan principles , the sub梚maging characters are depicted in this thesis After analyzing the recognition and tracking features, we build up the model of infrared sub-maging target recognition and tracking. The functions of infrared sub-maging target recognition DSP system are introduced, and its program flow charts are given0 Also, the implementation of key modules are discussed The experimental results show that the system can work well0 The special figure and size of a seeker required that we should develop a new mini system, And so, we redesign the above system0 The mini one proves stable and efficient, which means it has the ability of real time process 0 Finally, the design and implementation of "foot Load?function in the new one is discussed0 Because the system's software has more redundancy, we modified its functional state as well as optimized its implemental ways. The results hnw that the process time of this new system is reduced from l6Oms to 25ms0 Obviously, the system's processing speed is largely improved0 "racking and Prediction?are key technologies in the aerial infrared target recognition and tracking system0 To compare the real-time and transplanting performance of four different algorithm, we developed a simulation software base on Windows 98 and Visual C++ 6. 0 platform0 And the conclusion is drawn that hybrid prediction method is the most suitable one to be implemented on a DSP system0...
