Plateau wetland intelligent fine extraction method based on high-resolution remote sensing image

The invention discloses a plateau wetland intelligent fine extraction method based on a high-resolution remote sensing image. The method comprises the steps that high-spatial-resolution image data and DEM data of a target area are acquired and preprocessed; based on the high-spatial-resolution image data, sensitive features to water and vegetation are extracted; wetland hydrological characteristics and wetland ecological rules are extracted based on DEM data; fusing the sensitive features and the wetland hydrological features; performing multi-scale segmentation on the fused feature image to obtain a plurality of segmentation objects; dividing the plurality of segmentation objects into water body image data and non-water body image data based on the sensitive features and the wetland hydrological features; classifying the non-water body image data to obtain non-water body classification image data; and reclassifying the water body image data and the non-water body classification image data based on a wetland
