摘要
论文以可见光卫星图像中码头停靠的舰船目标为研究对象,提出一种新的码头与停靠舰船的分割方法。该方法根据码头区域的平直几何特征,利用改进的Hough变换提取码头轮廓,通过二次分割将停靠舰船与码头分离,从而解决了由于停靠舰船与码头区域连接,无法根据灰度特性将舰船目标与码头区域完整地分割的困难,达到准确识别舰船的目的。
In this paper,the method for detection of ships stopped by dock from visual image is studied.Because stopped ships are closed with the dock and their gray feature is similar,it cannot deal them as moving ships by segmentation using their gray feature.Depending on the line regular geometry feature of the dock,it put s forward a new ship and dock target segmentation method and realizes the purpose of the exact ship detection.
