Water body extraction method, equipment, medium and product

Abstract

The invention discloses a water body extraction method and device, a medium and a product, and relates to the field of remote sensing image processing.The method comprises the steps that a plurality of independent water body indexes with the water body extraction precision meeting the preset requirement are screened out from a plurality of independent water body indexes and recorded as candidate water body indexes; combining the plurality of candidate water body indexes in pairs to obtain a plurality of initial combined water body models; determining the initial combined water body model with the highest water body extraction accuracy from the plurality of initial combined water body models, and recording the initial combined water body model as the highest combined water body model; and extracting all water bodies in the regional range from the remote sensing image based on the highest combined water body model. The water body extraction precision is improved.
