An automatic extraction method and system for remote sensing coastlines based on residual space pyramid segmentation and double-dimensional attention

Abstract

The application provides a remote sensing coastline automatic extraction method and system based on residual space pyramid segmentation and double-dimension attention, and relates to the technical field of spatial analysis.The method of the application comprises high-resolution remote sensing image acquisition and preprocessing, land-sea segmentation network reasoning, probability graph thresholding, edge extraction and vectorization processing.The method improves segmentation accuracy through multi-scale feature aggregation and attention enhancement, generates coastline vector data with geographic coordinates by combining edge detection and topological repair, and is suitable for spatial analysis and coastline monitoring.
