ONERA/SARLO-80
收藏资源简介:
SARLO-80数据集是一个全球性的斜视SAR(合成孔径雷达)和光学图像配对数据集,包含119566对Umbra SAR和光学图像,以及相应的文本描述。SAR数据来源于Umbra SICD产品,经过重采样至固定的80 cm × 80 cm分辨率(方位和距离方向),并保持斜视几何。光学图像是高分辨率光学数据,经过重投影以匹配对应SAR获取的斜视几何。每对图像还包含三个自动生成的描述(短、中、长),这些描述是通过CogVLM2从光学图像生成,并经过Qwen LLM清理和后处理。数据集格式包括分辨率、模态配对和文本描述等信息,每个样本包含光学图像、SAR幅度图像、复数SAR数组、元数据和唯一键。
This dataset provides 119566 paired Umbra SAR, optical images in slant-range geometry and text description. SAR data come from Umbra SICD products, resampled to a fixed 80 cm × 80 cm resolution (azimuth and range) in slant-range geometry. Optical images are high-resolution optical data reprojected into the slant-range geometry of the corresponding SAR acquisition. Each pair also includes three automatically generated captions from the optical image using CogVLM2, then cleaned and post-processed with the Qwen LLM.
