Abstract The present invention provides an atmospheric scattering illumination removal-based cloud detection method and belongs to the meteorological field. The method includes the following steps of: sky image acquisition which is used for acquiring the color RGB image of the sky; an illumination background extraction which is used for determining an atmospheric scattering illumination background in the sky image so as to obtain an atmospheric scattering background image; illumination background removal which is used for removing atmospheric scattering background differences in the atmospheric scattering background image so as to obtain an illumination background removed image; threshold value segmentation: could in the illumination background removed image is detected through segmenting threshold values so as to obtain a threshold value segmented image; and sun perpendicularly irradiating region removal: a sun perpendicularly irradiating region is determined, could detection information in the sun perpendicularly ir
