摘要
针对高分辨率可见光遥感图像的航母目标识别问题,引入了最小惯性轴,提出了面积序列特征和长度序列特征的概念,并对其相似变换不变性进行了证明,通过最小惯性轴提取舰船目标区域的面积序列特征和长度序列特征,最后运用到对航母目标的识别中。实验结果表明,面积序列特征和长度序列特征具有良好的相似变换不变性,能够很好地表征舰船目标的轮廓和区域信息,准确地从舰船目标中分离出航母目标,对航母目标识别率高。
To identify the aircraft carrier in high resolution remote sensing visible light image,an method based on least inertia axis is proposed.The concepts of area and length sequence features of the ship targets are presented and explained,and both of them can be obtained by least inertia axis.Their similarity transformation invariance is proved and applied in aircraft carrier identification.Experiment results show that the area and length sequence features have good similarity transformation invariance.The outlines and region of ship targets can be well characterized by them.The aircraft carrier target can be precisely separated from the ship targets.The method has high correct identification rate.
