遥感仪器的定标是遥感信息定量化分析的关键技术之一,介绍高光谱成像仪实验室辐射定标的几种常用算法,结合实例分析采用两点法进行辐射校正后图像中出现条带的原因,给出解决方案,最终提高辐射校正的精度和图像质量。
The calibration of remote sensing instruments is one of the key technologies for the quantitative analysis of remote sensing information. Several commonly used algorithms of hyperspectral imager laboratory calibration are introduced, and the combination of two-point method is used to analyze the radiation bands in the images The reason for this is to provide solutions that ultimately improve the accuracy and image quality of radiation correction.
