摘　　要：针对红外掠海小目标对比度低,容易受到噪声、海面杂波、云层等干扰,导致跟踪失败的问题,提出了一种基于海天线的红外掠海小目标跟踪方法。通过对红外成像系统进行分析,利用拉普拉斯滤波抑制背景噪声,根据图像中海天线的位置信息,确定目标所在区域并进行目标检测。检测出可疑目标后,利用其灰度、尺寸、面积等特征信息,选出真实目标进行跟踪。实验结果表明,该算法对红外掠海小目标有很好的跟踪效果。In view of the problem of low contrast of infrared sea-skimming small target and easy interference from noise,sea clutter and cloud,which leads to tracking failure,a tracking method of infrared sea-skimming small target based on sea-sky line was proposed.Through analysis of infrared imaging system,the Pierre-Simon Laplace filter was used to suppress background noise,and according to position information of sea-sky line in image,the target area was determined and the target was detected.After detecting the suspicious target,the real target was selected by using feature information such as gray level,size and area.Experimental results show that the proposed algorithm has a good tracking effect for the infrared sea-skimming small target.
