The invention discloses a splicing type hyperspectral camera non-uniformity correction method and device and a storage medium, and the method comprises the following steps: independently carrying out the non-uniformity correction of each hyperspectral camera, and obtaining the correction coefficient of each hyperspectral camera; the method comprises the following steps of: performing non-uniform correction among different cameras on a spliced hyperspectral camera by utilizing an overlapped view field, and correcting a correction coefficient among the different cameras by utilizing a filtering algorithm when a spectral difference between a ground target in an overlapped region and a ground target in a non-overlapped region among the different cameras is greater than a preset error value, and the spectral difference is not greater than the preset error value, so that a hyperspectral image after non-uniform correction is obtained. The method has a good non-uniformity correction effect, retains the spectral chara
