Unmanned aerial vehicle foggy day optical image ground object identification method

The invention relates to the technical field of unmanned aerial vehicle foggy day identification, and discloses an unmanned aerial vehicle foggy day optical image ground object identification method, which comprises the following steps: a, image acquisition: acquiring a ground object image aerial-photographed by an unmanned aerial vehicle; b, decomposing the image: decomposing the foggy image to be processed into a basic component image and a detail component image; c, detail enhancement: performing detail enhancement processing on the detail component image; d, obtaining a grayscale image: obtaining the grayscale image Iray (x) of the detail component image after detail enhancement processing; according to the unmanned aerial vehicle foggy day optical image ground object identification method, firstly, a foggy image to be processed is decomposed into a basic component image and a detail component image, then, defogging processing is performed on a gray level image of the detail component image, detail enhanc
