phisat2-s2-lightglue-triplets
收藏资源简介:
该数据集名为“PhiSat-2 / Sentinel-2 LightGlue Triplets”,包含从本地PhiSat-2与Sentinel-2卫星图像的LightGlue处理流程中生成的最终严格三元组输出。每个被接受的图像补丁包含多种数据层:真实的PhiSat-2影像、Sentinel-2 L1C级影像、模拟的PhiSat-2影像、OmniCloudMask云掩膜、ESA WorldCover土地覆盖数据以及Koppen-Geiger气候分类元数据。数据集采用严格的质量控制策略,仅当补丁通过配准、几何校正、无数据检查、PhiSat-2云检测、WorldCover和Koppen门控等多重检验后才被纳入。当前版本包含1个最终配对、53个被接受的严格三元组和115个被拒绝的严格三元组。数据组织方式为:聚合索引存储在dataset_index.csv文件中,而每对的具体输出则位于pairs/<pair_id>/lightglue_coregistration/目录下。该数据集适用于图像到图像转换、图像分割等计算机视觉任务,特别关注遥感影像的配准与多源数据融合。
The dataset named PhiSat-2 / Sentinel-2 LightGlue Triplets contains final strict triplets generated from the LightGlue processing pipeline of local PhiSat-2 and Sentinel-2 satellite imagery. Each accepted image patch includes multiple data layers: real PhiSat-2 imagery, Sentinel-2 L1C imagery, simulated PhiSat-2 imagery, OmniCloudMask cloud mask, ESA WorldCover land cover data, and Koppen-Geiger climate classification metadata. The dataset employs a strict quality control strategy, where patches are included only after passing multiple checks such as registration, geometric correction, no-data checks, PhiSat-2 cloud detection, and WorldCover and Koppen gating. The current version includes 1 final pair, 53 accepted strict triplets, and 115 rejected strict triplets. Data is organized with aggregated indices stored in the dataset_index.csv file, and specific outputs for each pair are located in the pairs/<pair_id>/lightglue_coregistration/ directory. This dataset is suitable for computer vision tasks like image-to-image translation and image segmentation, with a focus on remote sensing image registration and multi-source data fusion.
