Mining area image recognition model construction method and device

The invention provides a mining area image recognition model construction method and device, and the method comprises the steps: obtaining an original optical satellite remote sensing image, and carrying out the preprocessing of the original optical satellite remote sensing image, and generating a first image block set; for a corresponding first image block in the first image block set, using a preset feature extraction algorithm to extract texture features, spectral features and index features of the first image block; generating a corresponding texture feature map, a spectral feature map and an index feature map; obtaining mineral label information corresponding to the first image block; and inputting the texture feature map, the spectral feature map, the index feature map and the mineral marking information corresponding to the first image block into a deep learning model for model training, and obtaining a mining area image recognition model through training. And the mining area identification precision i
