Based on the airborne image at a certain altitude, the reflectance was retrieved by the empirical linear method. The atmospheric reflectivity image was corrected by atmospheric radiation transmission software MODTRAN. The gray scale was obtained by the calibration coefficient of aerospace optical remote sensor.
