[0070] GPFX atmospheric correction is completed in two steps: (1) write the atmospheric correction program; (2) run the atmospheric correction program for atmospheric correction.
[0071] (1) Write the atmospheric correction program:
[0072] The GPFX atmospheric correction program adopts Visual Studio C#2008, and according to the technical plan ① the satellite remote sensing image is calibrated into a reflectivity image; ② the reflectivity image is separated into a ground object image and an atmospheric image; It is QB9963, with a total of 6673 lines of source programs, in which formulas (1)-(18) are rewritten into C# language programs to complete the above three operations, and supplementary image reading and writing, image browsing, parameter input and other auxiliary codes constitute QB9963. All the images of atmospheric correction results in this paper are completed by QB9963, and the "AA" version of QuickBird satellite remote sensing images is used to test the effect of ...
