摘要
Abstract
The super wide-field infrared staring system has unique characters such as vast detection airspace, passive detection, staring detection, and so on. However, when a super wide-field infrared staring system is used to detect weak and small targets, it may show complex background, more noise jamming and little target information. So the detection accuracy is always low. By using the idea of spatial-temporal fusion processing in super wide-field image, an improved method based on maximum background model prediction is proposed in the paper. Firstly, image preprocessing and multi-frame difference are carried out to select study regions. Then, the improved model is used to detect all suspicious targets in whole infrared image. At last, the real target is confirmed by neighborhood correlation rule. The experiment proves that:the Signal to Noise Ratio(SNR) of proposed method is increased more than5 times and the gray value of target is increased more than 10 times. Meanwhile, more target information is preserved than before. The time of target detection is decreased by more than 50% and the accuracy and efficiency of detection are improved.关键词
