Abstract

The invention discloses an earth surface deformation prediction method and system based on an InSAR technology and behavior characteristic deep learning, is applied to the technical field of earth surface deformation monitoring of the InSAR technology, and is used for obtaining image data, obtaining a prediction model based on an earth surface time sequence deformation prediction method combining the InSAR technology and a 3D-CNN network, and carrying out earth surface deformation prediction by combining noise reduction processing. According to the method, the ground surface settlement is monitored in a large range and with high precision through the InSAR technology, the economic investment of ground surface time sequence settlement monitoring can be effectively reduced, then the 3D-CNN network is utilized to learn ground surface time sequence deformation characteristics, the future ground surface deformation trend is predicted, and auxiliary decision making and technical support are provided for preventing ground surface settlement disasters; the method does not need to select a stable region to estimate deviation on a regional scale, carries out statistical analysis operation on the image after removing null values and abnormal values, can globally and automatically correct strip noise, and can retain useful information of a landslide deformation detection result to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of surface deformation monitoring of InSAR technology, in particular to a method and system for predicting surface deformation. 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. Therefore, facing the problem of land subsidence, it is urgent to monitor, analyze and p...
