Glacier extraction method and system based on multi-source multi-resolution remote sensing image fusion

The invention discloses a glacier extraction method and system based on multi-source and multi-resolution remote sensing image fusion, relates to the technical field of glacier remote sensing image processing, and solves the problem that the robustness and precision are difficult to guarantee when an existing glacier extraction method faces complex scenes. The method comprises the following steps: screening a high-resolution panchromatic image and a medium-low-resolution multispectral image, carrying out preprocessing to obtain a sample image, and constructing a sample data set of glacier in a naked ice region by using the sample image; the preprocessing comprises multi-source image fusion and dimension reduction processing; constructing a glacier boundary intelligent extraction model and performing training optimization on the glacier boundary intelligent extraction model by using the sample data set; preprocessing a to-be-interpreted remote sensing image, and extracting vector data of a glacier boundary in
