DEFORMATION INFORMATION EXTRACTION METHOD USING INSAR, TERMINAL, AND STORAGE MEDIUM

摘要

Disclosed is a deformation information extraction method using InSAR, a terminal, and a storage medium. The method comprises: A. extracting multiple initial PS points of a target structure; B. performing cluster analysis processing on the multiple initial PS points, obtaining multiple aggregation points, and recording the number of initial PS points corresponding to each aggregation point; C. calculating a distance between two adjacent aggregation points, and calculating a difference between the number of initial PS points corresponding to the two adjacent aggregation points; determining whether there are two adjacent aggregation points satisfying a preset singular aggregation point decision condition, wherein the preset singular aggregation point decision condition is that the distance is less than a preset distance threshold and the difference between the numbers is greater than a preset number threshold; D. if so, removing one of the two adjacent aggregation points, namely the aggregation point having the lesser number of initial PS points, and repeating step C until no two adjacent aggregation points satisfying the preset singular aggregation point decision condition remain; E. if no two adjacent aggregation points satisfying the preset singular aggregation point decision condition remain, extracting deformation information according to the remaining aggregation points. The present invention improves processing speed and analysis accuracy.
