Description

technical field [0001] The invention relates to the technical field of surface monitoring, in particular to a method for monitoring surface deformation. Background technique [0002] Currently, the technologies available for surface deformation monitoring include traditional GPS measurement, leveling, ground displacement measurement, DInSAR and TS-DInSAR technologies. Surface deformation is a frequent geological disaster, mainly including land subsidence (vertical deformation), landslide, volcanic activity displacement, earthquake displacement, mine subsidence, glacier movement, deformation of buildings and structures, etc., which will cause serious damage to human life, property and economic development. serious hazard. It is of great practical significance to monitor the surface deformation and provide important reference and decision-making basis for disaster prevention and control. [0003] Traditional GPS measurement, leveling measurement, and ground displacement meas...
