AI中文摘要：
合成孔径雷达（SAR）图像中的船舶检测对海上态势感知至关重要，尤其针对非法捕鱼、走私或边境违规等各类海上非法活动。采用神经网络的现代船舶检测方法通常需要大型训练数据集，但SAR领域的此类数据集远少于光电领域。尽管存在若干该任务的免费数据集，但其可用性和实用性各不相同。本文提出了基于知名的OpenSARShip 1.0数据集构建的OpenSARShip-船舶检测数据集（OSSDD），用于训练SAR船舶检测的神经网络。OSSDD可免费获取，包含15197个Sentinel-1的VV和VH极化幅度图像块、船舶二值掩码、轴对齐边界框和旋转边界框标注，共涉及55759艘船舶。本文展示并讨论了该数据集的构建过程、可下载数据的内容与结构，以及对Faster R-CNN、FCOS、DETR三种常用检测器模型开展的实验，实验结果可作为未来实验的基准。该数据集在Hugging Face上可通过此网址获取。
英文摘要：
Ship detection in Synthetic Aperture Radar (SAR) images plays an important role for maritime situational awareness, especially with respect to different illegal activities at sea such as illegal fishing, smuggling or border violations. Modern ship detection methods using neural networks usually require large training datasets, which are considerably scarcer in the SAR domain than in the electro-optical domain. While several free datasets exist for this task, their availability and usability vary. In this paper, OpenSARShip-Ship Detection Dataset (OSSDD), a new dataset based on the well-known OpenSARShip 1.0 dataset is proposed for training neural networks for SAR ship detection. OSSDD is freely available and contains 15,197 Sentinel-1 amplitude patches in VV and VH polarization, binary ship masks, axis-aligned bounding box and rotated bounding box annotations for a total of 55,759 ships. The construction of the dataset, the contents and structure of the downloadable data and experiments with three common detector models (Faster R-CNN, FCOS, DETR) are shown and discussed. The results serve as benchmarks for future experiments. The dataset is available on Hugging Face at https://huggingface.co/datasets/sylviaHoch/OpenSARShip-Ship-Detection-Dataset.
