<p>PROBLEM TO BE SOLVED: To eliminate influence of the atmospheric air by correcting the radiance measured by a spectrum sensor even when a uniform and flat subject is distributed in a large range in an observation region of the spectrum sensor.SOLUTION: The image processing system includes a spectral reflectance acquisition unit 5 that identifies, from one or more radiance patterns set by a radiance pattern setting unit 4, a radiance pattern most coincident with the radiance pattern of a low reflection object extracted by a histogram analysis unit 2, and acquires, from a ground surface spectral reflectance storage section 3, a spectral reflectanceρon the ground surface corresponding to a known low reflection object having the most coincident radiance pattern.</p> |
