Abstract


Precision-guided weapons , the most important part of the guidance system , infrared imaging guidance has the advantages of high sensitivity , anti-interference ability , good for hiding , has become the mainstream of today's world of precision guidance technology development and research and direction . This paper focuses on the infrared seeker image processing system of infrared image preprocessing point target detection , target identification and target tracking detailed discussion and research . First, in the analysis of the infrared image midpoint target , background , based on noise characteristics of infrared radiation to pre-treatment to remove low-frequency background threshold divided to noise image sequence detection the three links centric , analyzed and discussed in a row effective infrared point target detection algorithms ; Second, from target identification system , and pre-processing of image segmentation binarization and edge detection , and target feature extraction , BP neural network is trained to identify the target , given the the simulation results proved the effectiveness of the algorithm ; then part in target tracking to study target tracking algorithm , prediction and filtering, the location and size of the gate to the identification and tracking control problem ; Finally, the infrared seeker image processing algorithm overall analysis .
