Summarization of Rigorous Geometric Location Model for Images from High Resolution Remote Sensing Satellites

成像几何模型是遥感影像几何处理和地球空间信息提取的理论基础。在不同类型的几何定位模型中,严格几何定位模型具有高精度、高可靠性的优点,因此对严格几何定位模型的研究有非常重要的意义。综述了近年来国内外新出现的高分辨率卫星遥感影像严格几何定位模型,分析了典型的3种模型:SISAR软件实现的严格几何定位模型、基于单位四元数的严格几何定位模型和基于对偶四元数的严格几何定位模型,阐述了其理论基础和优缺点。由于基于对偶四元数理论所建立的几何模型可将光线束的位置和姿态统一用对偶四元数表示,因此对该模型的研究是一个新的具有内在潜力的发展方向。

Imaging geometric model is the foundation of geometric analysis of the remote sensing images and spatial information collecting.For different geometric location models,rigorous geometric models have the advantages of high-accuracy and high reliability,so it has great significance for the study of rigorous geometric models.In this paper,rigorous geometric models for images from high resolution remote sensing satellites in recent years are presented.Three typical rigorous geometric models,including the rigorous model implemented in the software SISAR,geometric models based on unit quaternion and geometric models based on dual quaternion,were introduced in special detail.Dual quaternion can describe the position and attitude of space image,so the study of geometric models based on dual quaternion has great development prospects.
