Title: Design of Width of Panchromatic Spectra of High Resolution Optical Remote Sensing Camera Based on Pansharpening
Abstract: The spectral distortion existing in the high resolution optical pansharpen image is mainly caused by the different width of panchromatic spectra from multispectral band of remote sensing camera.The paper firstly introduces the relative spectral response of multispectral and panchromatic band of some typical high resolution optical remote sensing satellites on-orbit.Then SPOT-5,IKONOS,GeoEye-1,ZY-3,Pleiades-1A and SPOT-6 images are selected to pansharpen experiment.The optimum width of panchromatic band 450-800nm is discussed in detail according to the minimum spectral distortion relative to the original multispectral image.The high spectral fidelity of pansharpen image can be produced by using the standard HIS and Brovey pansharpen algorithms with 450~800nm panchromatic image.
