线阵推扫成像光谱仪几何校正误差的理论分析

THEORETIC ANALYSIS OF GEOMETRICAL RECTIFICATION ACCURACY FOR LINEAR PUSHBROOM IMAGING SPECTROMETER

针对本课题组研制的线阵推扫成像光谱仪和GPS/INS组合定位的集成系统,分析了姿态位置参数、焦距测量和安装角测量引入的几何校正误差,并利用航空试验数据计算出了定量化的误差结果.

For the integration system consisting of linear pushbroom imaging spectrometer and GPS/INS integration positioning, geometrical rectification accuracy deriving from position and attitude parameters, focal length measuring and installation angles measuring were analyzed. Moreover, a quantitative result of accuracy was calculated with airborne experimental data.
