Description

technical field [0001] The invention relates to the field of atmospheric correction of remote sensing images, in particular to a method, system and storage medium for hyperspectral remote sensing image satellite-terrestrial collaborative atmospheric correction under the coordination of satellite-terrestrial observation data. Background technique [0002] The total radiance of the ground target measured by the remote sensor is not a reflection of the real reflected energy of the surface, which includes the radiation energy error caused by atmospheric absorption, scattering and other effects, especially the scattering effect. Atmospheric correction is the process of eliminating these radiation errors caused by atmospheric influences and retrieving the true surface reflectance of ground objects. Atmospheric correction refers to adjusting the measured values ​​of remote sensing images according to the atmospheric conditions to eliminate the influence of the atmosphere and carry ...

AI Technical Summary

Problems solved by technology

[0005] The existing atmospheric correction methods for hyperspectral remote sensing images have the following problems: (1) Inversion of atmospheric state parameters based solely on hyperspectral remote sensing images is mainly based on empirical models, and the accuracy is difficult to compare with synchronous observation data; (2) It is extremely difficult to observe atmospheric state parameters that have the same imaging area as hyperspectral remote sensing imaging and are strictly synchronized at all times, and the existing technical methods are not very operable
