摘　　要：针对当前多数高分辨遥感卫星面向用户服务存在获取数据种类单一问题,该文公开了双清一号(珞珈三号01星)多模式成像样例数据集,涵盖了面阵推扫、面阵推帧和视频凝视等多种成像模式,包含城市、水体、山区、机场等不同目标区域的典型数据样本。该数据集由信号数据解码、Bayer插值、相对辐射校正、几何定位、视频稳像和3维重建等步骤处理构建;同时,对在轨定标、兴趣区产品快速生产、高清视频几何稳像和多角度3维重建等关键算法做了深入探讨和研究。最后,对样本数据集从图像标准产品、凝视视频产品和实景3维产品等3个方面进行了可视化展示和定量化精度评价。Herein,the Shuangqing-1(Luojia3-01)multimode imaging sample dataset is presented to address the problem of limited data types provided for user services by remote sensing satellites with the highest resolution.This dataset includes various imaging modes,such as push-scan,array push-frame,and video staring;hence,it covers typical data samples from different target areas,such as urban regions,water bodies,mountainous regions,and airports.The construction of this dataset involves signal data decoding,Bayer interpolation,relative radiometric correction,geometric positioning,video stabilization,and three-dimensional reconstruction.Additionally,in-depth discussions and investigations are conducted on key algorithms,such as on-orbit calibration,rapid production of area of interest products,high-definition video geometric stabilization,and multi-angle three-dimensional reconstruction.Finally,the sample dataset is visually displayed and quantitatively evaluated from three aspects:image standard,video staring,and real-world three-dimensional products.
