Abstract

The invention discloses a method and a device for monitoring surface deformation and data processing equipment. The method comprises the following steps: obtaining satellite radar images of a target area; obtaining pixels of the satellite radar images of the target area; obtaining an interferogram of the target area by applying complex operation to the pixels; and obtaining the surface deformation data of the interferogram. According to the invention, the interferogram, which is obtained from the pixel data of the satellite radar image data sent by the satellite, contains data information representing surface deformation and other data information, and the data information representing surface deformation can be obtained by filtering other information, so as to quickly and accurately detect the sedimentation effect of a mining area.

Description

technical field

[0001] The invention relates to the field of surveying, in particular to a monitoring method and device for surface deformation and data processing equipment. Background technique

[0002] Excessive mining of mineral resources can easily damage the underground geological structure of the mining area, causing accidents such as surface subsidence, landslides, avalanches, debris flows, ground fissures, ground subsidence, and ground water, and even water seepage accidents in the mining area, causing serious safety hazards and even casualties. Through the long-term and dynamic subsidence monitoring of the mining area and the analysis of the subsidence law of the mining area, the damage degree of the geological environment of the mining area can be grasped in time, so as to formulate corresponding emergency treatment plans according to the actual situation. At the same time, the surface deformation data information of the mining area can provide data support for th...
