Abstract

The invention provides a method and device for constructing a three-dimensional earth crust deformation model, and relates to the technical field of data processing, and the method comprises the steps: obtaining first target data in a target region, and constructing a time sequence of a plurality of time scales based on the first target data; performing optimal fitting on the time sequences of the multiple time scales by using a nonlinear autoregression model algorithm to obtain an optimal linear fitting time sequence of the CORS station; performing refining processing on the three-dimensional earth crust deformation field function model of the CORS station by using the optimal linear fitting time sequence of the CORS station to obtain an optimal time sequence of the CORS station; and constructing a three-dimensional earth crust deformation model of the target area based on the optimal time sequence, thereby solving the technical problem that the time resolution and the spatial resolution of the existing three-dimensional earth crust deformation model are relatively low.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for constructing a three-dimensional crustal deformation model. Background technique [0002] Crustal deformation is directly or indirectly related to human living environment, climate change, earthquakes, and geological disasters. The impact process of crustal deformation is extremely complex, not only has long-term linear effects such as tectonic movement and post-glacial rebound, but also is affected by nonlinear effects of complex surface dynamic environments such as atmosphere, surface water, groundwater, glaciers, snow-capped mountains, and sea level changes. Or there are large differences on different time scales. [0003] GNSS technology can directly observe the movement and deformation of the earth's surface with high precision. In actual research and application, mathematical methods such as Kriging method, inverse distance weighting method,...
