舰船斜框检测数据集(RSDD-SAR)

舰船斜框检测数据集(Rotated Ship Detection Dataset in SAR Images, RSDD-SAR)，采用了国产高分3号卫星数据和欧空局TerraSAR-X卫星数据。该数据集由84景高分3号数据和41景TerraSAR-X数据切片及2景未剪裁大图，共127景数据构成，包含多种成像模式、多种极化方式、多种分辨率切片7000张，舰船实例10263个，具有旋转方向任意、长宽比大、小目标占比高和场景丰富的特点。图1为RSDD-SAR数据集典型场景切片示例。The Rotated Ship Detection Dataset in SAR Images (RSDD-SAR) is constructed using SAR data from the domestically-developed Gaofen-3 (GF-3) satellite and the TerraSAR-X satellite of the European Space Agency (ESA). This dataset consists of 127 scenes in total, including 84 cropped scenes from GF-3 data, 41 cropped scenes from TerraSAR-X data, and 2 uncropped full-size images. It contains 7000 image slices with diverse imaging modes, polarization modes and spatial resolutions, as well as 10,263 annotated ship instances. The dataset features arbitrarily rotated ship targets, large aspect ratios, a high proportion of small-sized targets, and diverse background scenarios. Figure 1 shows examples of typical scene slices from the RSDD-SAR dataset.
