成像光谱图像处理中的光谱吸收指数及吸收鉴别模型

王晋年,郑兰芬,童庆禧:成像光谱图像光谱吸收鉴别模型与物填图研究。环境遥感,199611(1)

(1)成像光谱图像处理中的光谱吸收指数模型:

式中,,为吸收的对称性参数;,为吸收波段宽度;分别为吸收左肩端的反射率和波长位置;分别为吸收点的反射率和波长位置;分别为吸收右肩端的反射率和波长位置;a为放大系数;为传感器的光谱响应;为目标的辐照率;为大气的透过率;为反射率;7为地形因子。

(2)成像光谱图像光谱吸收鉴别模型:

式中,分别为吸收肩端图像与吸收图像的灰度值;为波段的光谱采样间隔;为大气辐射;为“暗电流”值;值包含程辐射和成像光谱仪光谱响应、放大增益等信息。
