AI Technical Summary
Technical Problem
It is difficult to quickly and accurately obtain underwater topographic data of large water bodies, especially in water bodies of strategic importance.
Method used
By partitioning the inversion water area, it is divided into deep water area and shallow water area transformed into water and land transformed. The spatial interpolation method and a model constructed based on band reflectivity information and underwater terrain elevation data are respectively inverted, and the topographic images of the two areas are finally stitched and fused.
Benefits of technology
More precise inversion of the underwater terrain of large water bodies is achieved, avoiding the errors caused by a single method to deal with complex and diverse water bodies, and improving the accuracy of inversion.

Abstract
The invention provides a large-scale water body underwater terrain inversion method and device and a medium, and the method comprises the steps: carrying out the partitioning of a to-be-inverted water body region, and obtaining a deep water region and a land-water conversion shallow water region; based on a spatial interpolation method, carrying out inversion on the land-water transformation shallow water area to obtain a land-water transformation shallow water area topographic image; a deepwater area water depth inversion model constructed based on the wave band reflectivity information and the underwater topographic elevation data performs inversion on the deepwater area to obtain a deepwater area underwater topographic image; and carrying out image splicing fusion on the land and water transformation shallow water region topographic image and the deep water region underwater topographic image to obtain the underwater topography of the water body to be inverted. In the face of a complex and changeable water body environment, a water body area to be inverted is divided into a deep water area and a land and water conversion shallow water area, and different and more targeted inversion methods can be adopted according to the characteristics of water bodies in different areas.
