提出了一种可操作的正射校正解决方案，支持当前可用成像光谱测量数据的组合几何和辐射处理。所描述的参数地理编码程序（PARGE）严格考虑飞机和地形几何参数，并使用正向变换算法创建正射成像光谱测量立方体。讨论了目前应用的处理器的实现原理、辅助数据标定策略以及工作流程。识别了该方法的主要误差源，并展示了如何充分利用可用的辅助数据惯性导航系统/全球定位系统（INS/GPS）参数的可能性。 HyMap 和 AVIRIS 成像光谱测量数据的结果显示此类图像的绝对精度在 1-3 像素范围内。本文第二部分展示了 PARGE 与大气校正程序的结合。所描述的地球大气工作流程被提议作为现有和未来成像光谱测量数据的标准处理方法。
An operational ortho rectification solution in support of the combined geometric and radiometric processing of currently available imaging spectrometry data is presented. The described parametric geocoding procedure (PARGE) strictly considers the aircraft and terrain geometry parameters and uses a forward transformation algorithm to create orthorectified imaging spectrometry cubes. The implementation principles, the auxiliary data calibration strategies, and the workflow of the currently applied processor are discussed. The major error sources of the approach are identified, and possibilities are shown how to make the most out of the available auxiliary data Inertial Navigation System/Global Positioning System (INS/GPS) parameters. Results on HyMap and AVIRIS imaging spectrometry data show an absolute accuracy in the range of 1-3 pixels for this kind of imagery. The combination of PARGE with an atmospheric correction procedure is shown in part 2 to this paper. The depicted geo-atmospheric workflow is proposed as a standard processing approach for available and future imaging spectrometry data.
