Abstract:

A wide true color image processing method was proposed for the second generational medium resolution spectrum imager (MERSI-Ⅱ) on board the Chinese Fengyun-3D (FY-3D) polar orbit meteorological satellite.Using this method, the true color-composed image was realized by atmospheric correction and segmented enhancement for the three 250 m resolution visible bands of MERSI-Ⅱ.Then the seamless mosaic of multi-track images was realized based on pixel weighted fusion method and Wallis dodging algorithm.The application cases show that this method can obtain high-quality and intuitive remote sensing monitoring images, and effectively solve the limitation of scanning width of polar-orbit meteorological satellite's single-track data.This method is helpful to use polar orbit satellite data in monitoring services during emergency response.
