Key Technology Of Infrared Sub-imaging Study

The infrared guiding technique is the research focus of precise guiding weapon and the infrared sub-imaging guiding technique has become an important developing branch of infrared guiding technique. The study about the key techniques of infrared sub-imaging has been carried out in the following aspects:Based on the principle of rosette scan sub-imaging and the analysis of the target recognition and tracking features, the model of infrared sub-imaging target recognition and tracking is built up in this dissertation.The target recognition algorithm of infrared sub-imaging has been studied and its software has been developed. The flow diagram and implement of several important module of target recognition software is brought forward in this dissertation.Compression codec has been studied and SPIHT codec is introduced into the image guidance system. The simulated result shows that the memory space is maximally compressed.Based on SPIHT, the ROI codec and perceptually-tuned algorithm aiming at recognition system are put forward in this dissertation. The former improve probability of target recognition through advancing image quality of region of interest, but the latter through attaining more edge information.
