Abstract
A method, a system, a device and a medium for landslide identification based on full Polarimetry Synthetic Aperture Radar (full PoISAR) are provided. The method mainly includes: registering target full PoISAR data with target optical remote sensing data and target digital elevation model data to obtain a first registration result and a second registration result; determining a polarization feature, a decomposition feature, and a terrain feature of a target area according to registration results; determining a texture feature and a hue feature of the target area according to the target full PoISAR data; determining a spectrum feature of the target area according to the target optical remote sensing data; fusing abovementioned multi-dimensional features to obtain a target fusion feature; and inputting the target fusion feature into a landslide mass identification model for identifying a landslide mass, so as to determine a landslide area in the target area.
