Abstract

The invention relates to the technical field of three-dimensional model construction, and provides a three-dimensional terrain model generation method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining contour lines forming a target model, carrying out the uniform sampling of the contour lines to obtain three-dimensional sampling points, and constructing a grid based on the three-dimensional sampling points; distributing the three-dimensional sampling points in grids of the grids, and taking Z coordinate values of the three-dimensional samplingpoints falling into the grids as basic elevation values of the grids; based on the existing basic elevation value on the grid, inserting a newly added elevation value into the blank grid of the gridby utilizing a preset interpolation algorithm; and generating a three-dimensional terrain model on the grid based on the basic elevation value and the newly added elevation value. According to the method, the surface of the three-dimensional terrain model can be smoother, and the visualization effect is better.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional model construction, in particular to a method, device, electronic equipment and storage medium for generating a three-dimensional terrain model. Background technique [0002] 3D terrain modeling is to establish a surface model that describes a certain part of the earth's surface and its characteristics, which can truly reflect surface characteristics and surface phenomena. It has been more and more widely used in geographic information, engineering construction, film and television animation, virtual simulation and other fields. . [0003] 3D terrain modeling requires the input terrain data source to be contour data, and then perform surface modeling based on the contour, and fit the 3D terrain according to the contour, usually using triangulation to construct the terrain, but the effect is poor and will produce The extra grade change lines do not correspond to the fact that t...
