摘要
目的对获取的丰镐地区航空高光谱遥感数据进行前期数据处理和校正。方法通过辐射校正、噪音去除、航带间差异调整、几何校正等图像处理方法对畸变和误差较大的遥感数据进行校正。结果获得了高质量、高精度的数据,为后续光谱定标、分类识别及信息提取提供了理想的图像。结论本方法对校正航空高光谱图像存在的较为严重的辐射畸变和几何畸变有良好效果。
Aim To correct the hyperspectral remote sensing images in Fenghao area. Methods Using radiometric correction, noise removal, image difference adjustment between flight courses, geometrical correction and other methods to correct the remote sensing data. Results High quality and high accuracy images were obtained, which ed images to the following spectral calibration, classification and information extraction. Conclusion This method have good effect on correcting the images.
