Abstract

The invention relates to a three-dimensional model simplification method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring target information of vertexes on a triangular patch in an initial three-dimensional model; traversing all triangular patches in the initial three-dimensional model, and determining the grid type of the triangular patches according to the target information of the vertexes on the triangular patches; the grid type comprises a two-dimensional manifold grid and a non-two-dimensional manifold grid; determining a common edge between the triangular patch of the two-dimensional manifold grid and the triangular patch of the non-two-dimensional manifold grid, and simplifying an edge to be simplified in the triangular patch of the two-dimensional manifold grid to generate a simplified triangular patch; and constructing a simplified three-dimensional model based on the simplified triangular patch and the triangular patch of the non-two-dimensional manifold grid. By adopting the method, the problem of surface breakage occurring when the three-dimensional model is simplified can be solved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a three-dimensional model simplification method, device, computer equipment and computer-readable storage medium. Background technique [0002] With the development of image processing technology, 3D model technology has been widely used in many fields. For example, substations in the power field are often represented by 3D models. The 3D models of substations are often described by polygonal mesh models, especially triangular mesh models. More triangles. The huge number of triangular faces is a big challenge for computer analysis, display and storage. Therefore, it is necessary to simplify the complex 3D model with a large number of triangular faces in order to reduce the storage space of the computer and speed up the processing speed of the computer. [0003] Existing 3D model simplification methods mainly include vertex clustering algorithm and edge colla...
