| titleOfInvention | Water body atmosphere correction method and system based on image self statistical characteristics and storage medium |
| abstract | The invention discloses a water body atmosphere correction method, a system and a storage medium based on image self statistical characteristics, wherein the method comprises the following steps: firstly, selecting a water body pixel positioned in a shadow on an image, a non-shadow water body pixel close to the water body pixel, a cloud layer pixel close to an optical characteristic and a clean water body pixel, and counting the radiation characteristics of the four pixels; based on the four-pixel statistical characteristics, the atmospheric radiation contribution, the sky diffuse scattering descending irradiance and the total descending irradiance ratio are deduced and calculated by using a radiation transmission theory; assuming the reflectivity of a green wave band of the clean water body to be a fixed value, and calculating the reflectivity of a cloud layer; and finally, calculating the reflectivity of each pixel on the image through the cloud layer reflectivity, the radiation characteristics and the derivation relation between the atmospheric radiation contribution and the remote sensing reflectivity, and finishing the atmospheric correction of the water body. The method solves the problem that the conventional atmospheric correction of high-frequency multi-temporal image data is poor in comparability, and can realize atmospheric correction of turbid water bodies through the self statistical characteristics of the images. |
