Unsupervised regional change detection method and device for ground-based micro deformation monitoring radar image and storage medium

Abstract

This disclosure relates to a method, apparatus, and storage medium for detecting regional changes in unsupervised ground-based micro-change monitoring radar images. The method includes: acquiring a time series of images of a target area; obtaining the correlation between the time series images at equal intervals; obtaining an initial difference map based on the correlation images; and clustering the processed initial difference map to obtain change detection results. Through the various embodiments of this disclosure, the difficulties of ground-based micro-change monitoring radar, such as high noise levels, difficulty in distinguishing images before and after changes, and difficulty in obtaining difference maps, are overcome.
