Texture map obtaining method and device, electronic equipment and storage medium

Abstract

The invention provides a texture map obtaining method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a plurality of groups of region images of different regions of a target object, each group of region images in the plurality of groups of region images being obtained by photographing the same region of the target object in different light source directions; performing mapping calculation on each group of region images in the plurality of groups of region images to obtain color maps and normal maps corresponding to the plurality of groups of region images; and performing projection transformation and abutted seam fusion on the color chartlets and the normal chartlets corresponding to the multiple groups of regional images to obtain a material chartlet of the target object. In the implementation process, mapping calculation is carried out on each group of area images in the multiple groups of area images, and projection transformation and abutted seam fusion are respectively carried out on the color mapping and the normal mapping corresponding to each group of area images, so that the material mapping capable of showing the sense of reality of the plane material is obtained, and the sense of reality of the plane material is effectively improved.

Description

technical field [0001] The present application relates to the technical fields of computer data processing and image processing, and in particular, to a method, device, electronic equipment and storage medium for acquiring texture maps. Background technique [0002] Texture Mapping, also known as texture mapping, is to wrap the bitmap stored in the memory on the surface of the 3D rendering object in computer graphics. The texture map provides rich details for the object and simulates it in a simple way. complex appearance. An image (texture) is pasted (mapped) onto a simple shape in the scene, just like a decal is pasted onto a flat surface. This greatly reduces the amount of computation required to create shapes and textures in the scene. [0003] At present, in the process of game animation and film and television video rendering, art works with flat materials such as calligraphy and painting are usually scanned and rendered to reflect color details to express a sense of...
