A METHOD FOR EXTRACTING AND MANAGING INFORMATION OF SURFACE UNEVEN DEFORMATION OF AIRPORT IN RECLAMATION AREA

The present invention discloses a method for extracting and managing information of surface uneven deformation of airport in reclamation area, which mainly relates to the technology field of surface deformation monitoring and information processing, including: step 1: preprocessing the original SAR image, and based on the time series InSAR technology, acquiring the uneven deformation information of the airport surface with image coverage; step 2: dividing the airport in the reclamation area into n areas according to the time of reclamation construction (n is the number of reclamations), and then establishing the basic surface deformation database of the airport in the reclamation area according to the divided area; step 3: on the basis of the surface deformation database, calculating to obtain the surface deformation trends of n areas; step 4: with the continuous acquisition of external multi-source data, updating the basic surface deformation database of the airport in the reclamation area to form a benign cycle of monitoring the surface deformation in the study area. It constitutes a complete system for extracting and managing information of surface uneven deformation, and provides a strong basis for the scientific prevention and control of surface deformation in reclamation airports.
