Remote sensing image retrieval network training method, application method, electronic equipment and medium

The invention relates to a remote sensing image retrieval network training method, an application method, electronic equipment and a medium. The method comprises the following steps: acquiring a remote sensing image data set; constructing an initial remote sensing image retrieval network; taking a remote sensing image as input of the initial remote sensing image retrieval network, extracting multi-scale features of the remote sensing image based on a feature extraction module to obtain multi-scale feature data, and determining a binary hash code based on a hash coding module; and determining a value of a loss function of the initial remote sensing image retrieval network according to a binary hash code and a classification code, and adjusting parameters of the initial remote sensing image retrieval network according to the value of the loss function until a convergence condition is met to obtain a completely trained remote sensing image retrieval network. The multi-scale features of the remote sensing images
