Computer-implemented method for identifying active geohazards based on fusion of multi-source remote sensing images

Abstract

Disclosed is a computer-implemented method for identifying active geohazards based on the fusion of multi-source remote sensing images, including: processing SAR images acquired by SAR satellites covering a research area, and selecting a suspected geohazard occurrence area covering the research area as a target area; acquiring a plurality of satellite remote sensing image data covering the target area through remote sensing satellites; performing image preprocessing on the satellite remote sensing image data; performing secondary processing on the preprocessed satellite remote sensing image data to obtain millimeter to-meter level deformation information; statistically identifying motion pixels in the millimeter-to-meter level deformation information using an MCD :method; processing the motion pixels using a DBSCAN method, and delineating a position and boundary of active geohazards; and setting a slope within the active geohazards range, and identifying the geohazards according to the slope to obtain an identification result.
