【摘要】：以高光谱分辨率的空间外差光谱仪为例,针对其获取地表目标干涉数据的特点,提出一种利用高空间分辨率遥感图像中海岸线区域的大面积均匀地貌且地表反射率有突变的特征来对空间外差光谱仪进行指向配准的方法,实现了不同轴成像遥感设备与非成像遥感设备之间的匹配应用.利用空间外差光谱仪在多个对地观测点的结果干涉数据和相同经纬度区域的高空间分辨率图像数据进行地基测试实验,将配准校正值结果与其标称值进行对比,误差范围在-3%~5%.结果表明,该方法可为星载不同轴成像遥感设备与非成像遥感设备之间匹配应用提供参考依据.
[Abstract]:Taking the spatial heterodyne spectrometer with hyperspectral resolution as an example, aiming at the characteristics of obtaining the interference data of the surface target, A method of pointing registration of spatial heterodyne spectrometer based on large area homogeneous landform and abrupt surface reflectivity in high spatial resolution remote sensing image is proposed. The matching application between different axis imaging remote sensing equipment and non-imaging remote sensing equipment is realized. The interference data obtained from the spatial heterodyne spectrometer at multiple observation points and the number of high spatial resolution images in the same longitude and latitude region are used. According to the foundation test experiment, By comparing the registration correction results with its nominal values, the error ranges from -3 to 5. The results show that this method can provide a reference for the matching between space-borne imaging remote sensing equipment with different axes and non-imaging remote sensing equipment.
