Abstract
Description
Technical Field
[0001] This application relates to the technical field of geological disaster monitoring, and particularly to a method, system, and storage medium for distinguishing InSAR deformation types with multi-level constraints. Background Art
[0002] The InSAR technology is one of the important means of ground observation technology and has been widely used in long-term monitoring of small surface deformations. By obtaining surface deformation information through multi-temporal interferometric measurement and mastering the mechanism and trend of surface deformation, it helps to evaluate potential risks. Currently, the InSAR deformation type distinction method mainly uses the persistent scatterer interferometric measurement technology to obtain a discrete point set PS composed of high-coherence pixels, calculates the deformation of it, and separates the active PS and inactive PS points through a clustering method. Combining additional data sources such as landslide catalog data, urban vector data, and terrain data in the study area, it uses expert interpretation to semi-automatically distinguish landslide active deformation areas, ground settlement deformation areas, etc. However, currently, using the persistent scatterer interferometric measurement technology to distinguish deformation area types involves a large amount of data and low operation efficiency, and there are certain limitations for the monitoring application of large-scale and wide-area surface deformations.

However, for the different spatial distribution characteristics of landslides, mining collapses, settlements, and glacier deformations, the degree of automation of InSAR deformation area classification detection is relatively low.
