摘    要:针对高分辨率TerraSAR-X船舶图像,提出一种基于结构特征的两阶段船舶识别方法。所识别船舶包括油船和货船两大类,根据船舶结构的不同将油船分为显示油管油船和不显示油管油船,货船分为闭合货船和不闭合货船。识别第1阶段根据船体内是否有孔洞将闭合货船与显示油管油船分为一类,不闭合货船和不显示油管分为另一类;识别第2阶段根据船体内最长直线是否在船体中部将闭合货船与显示油管油船分开,根据船体内是否可以截断直线将不闭合货船和不显示油管油船分开。实验结果表明,采用本文方法进行船舶识别能够得到较好的识别结果。

关 键 词:高分辨率  Terra SAR-X  船舶识别  结构特征  SAR

Abstract:In this paper,we present a two-stage vessel recognition method based on structural features of high resolution TerraSAR-X images.We analyze two categories of vessels:tanker and cargo ship.The tanker class includes tube-showing-tanker and no-tube-showing-tanker.The cargo ship class includes closed rail cargo ship and open rail cargo ship.In the first recognition phase we distinguish closed rail cargo ships and tube-showing-tankers as one class from no-tube-showing-tankers and open rail cargo ships based on whether the ship body possesses holes.The second phase discriminates closed rail cargo ship from tube-showing-tanker based on whether the longest lines of the ship exist in the middle region of the vessel or not.The discrimination of open rail cargo ship from no-tube-showing-tanker is based on whether or not the ship body could cut off line.We obtained good experiment result with our method.
Keywords:high resolution  TerraSAR-X  vessel recognition  structure feature  SAR
