针对机载红外弱小目标机载抖动、动态背景以及内在噪声等导致目标难检测问题，提出一种卷积模板并结合滤波算法，进行图像预处理，然后利用全局运动反射模型估计背景，再应用背景差分以及目标聚类识别，提取疑似目标，最后利用这些疑似目标进行管道区域化判定，即目标轨迹具有连续性出现的疑似目标是真目标，否则为假目标。
針對機載紅外弱小目標機載抖動、動態揹景以及內在譟聲等導緻目標難檢測問題，提齣一種捲積模闆併結閤濾波算法，進行圖像預處理，然後利用全跼運動反射模型估計揹景，再應用揹景差分以及目標聚類識彆，提取疑似目標，最後利用這些疑似目標進行管道區域化判定，即目標軌跡具有連續性齣現的疑似目標是真目標，否則為假目標。

According to the airborne jitter,dynamic background and internal noise of the airborne infrared weak targets, target detection has become a difficult problem.In this article,a kind of convolution template,which combined with filtering algorithm,is presented for image preprocessing.Then in order to estimate the background,the reflection model of global motion is proposed.What’s more,by using adaptive background subtraction algorithm and clustering recognition,the sus-pected targets can be extracted.Those suspected targets are used for pipeline regionalization,that is,suspected targets tra-jectory with continuity are the real goals,otherwise are false targets.
