Texture mapping method and system, computer and readable storage medium

Abstract

The invention provides a texture mapping method and system, a computer and a readable storage medium. The method comprises the following steps: performing plane clustering on each mesh triangular surface; the texture quality of the projection area of each mesh triangular surface on the corresponding candidate image list is calculated, and a corresponding optimization energy equation is listed; a corresponding texture block is obtained through optimization of the optimization energy equation; according to the vertex color on the boundary of each texture block, determining the difference constraint between the texture blocks and the barycentric coordinates in the triangular surface of the grid, so as to construct a corresponding sparse linear equation; fusing the boundary color of each texture block according to a preset linear equation; and splicing the fused texture blocks into a texture picture, and outputting a target grid model with the texture picture. By means of the method, the distortion and chromatic aberration problems of large-scale complex model texture mapping can be effectively eliminated, and more real three-dimensional model reconstruction can be achieved.

Description

technical field [0001] The present invention relates to the technical field of data processing, and in particular, to a texture mapping method, system, computer and readable storage medium. Background technique [0002] Along with texture mapping is the process of establishing the correspondence between the surface of a three-dimensional object and the pixel coordinates of a two-dimensional image space. In 3D reconstruction, texture mapping uses the real natural scene photos collected by the user as 2D texture data, but each frame image can only capture a local area of ​​the natural scene, so it is necessary to combine multiple frame images to create 3D texture data. The full texture map of the model. [0003] However, most of the texture mapping in the prior art can only deal with relatively smooth original mesh models or small and medium-sized image data, and cannot deal with significant color differences, and does not eliminate the textured partial area images caused by ...
