摘    要:针对恶劣成像条件下有碎云干扰的光学遥感图像中舰船目标的检测问题,结合干扰背景及目标自身的特点,本文提出一种鲁棒的舰船目标检测算法。该算法首先用双参数局部CFAR直接提取ROI;再结合改进的局部Radon变换及变换域峰值提取算法,提取舰船目标的外部信息——尾迹特征,完成对舰船的检测。实测数据的实验表明,该方法能够可靠地检测出舰船目标,并有效地去除了碎云干扰所造成的虚警。

关 键 词:舰船检测  碎云  双参数CFAR  局部Radon变换  尾迹

Abstract:Focusing on the problem of ship detection in poor imaging conditions,which means here,being disturbed by lots of ragged clouds in optical images,a robust ship detection algorithm is proposed based on the characteristics of the background and the target itself.Firstly,it extracts ROI using two parameters and local CFAR.Then it extracts the wake information by the improved local Radon transform and a peak value extraction algorithm in succession.The experiments of satellite images show that this method can reduce false alarms caused by ragged clouds effectively.
Keywords:ship detection  ragged clouds  CFAR  local Radon transform  wake
