Three-dimensional cartoon face texture generation method and device

Abstract

The invention provides a three-dimensional cartoon face texture generation method and device. The three-dimensional cartoon face texture generation method comprises obtaining a standard texture mapping template of a three-dimensional cartoon face model and defining a texture Mask area in the standard texture mapping template; triangulating feature points inside a two-dimensional picture on the basis of a triangular mesh topological structure of the texture Mask area and obtaining a triangular mesh inside part of the two-dimensional picture corresponding to the triangular meshes inside the texture Mask area. The three-dimensional cartoon face texture generation method further comprises deforming the part of the two-dimensional picture and superposing the deformed part of the two-dimensional picture on the standard texture mapping template. The three-dimensional cartoon face texture generation method and device can generate a three-dimensional cartoon face texture mapping of relatively good effects simply by utilizing a single front face picture, and can enhance the similarity between a two-dimensional picture model and a picture to some extent.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a method and device for generating a three-dimensional cartoon human face texture. Background technique [0002] Texture Mapping, or texture mapping, is an important technology in the field of computer graphics and computational visualization. At present, texture maps are widely used in the development of shape design of industrial products, 3D simulation, 3D games, virtual reality scenes, etc. Texture mapping technology is a technology that maps and superimposes images (usually in the form of bitmaps) onto computer three-dimensional objects. Through texture mapping, it is possible to construct texture features on the surface of objects of various shapes, imitate various materials, and realize complete simulation of scenery and environment. Because texture mapping can achieve realistic visual effects without changing the geometric information of the 3D model, and it c...

Problems solved by technology

However, the problem with using a single photo is that due to the lack of side information, the texture generation effect of the side part is not good enough, which affects the overall effect

Moreover, the textures generated by existing methods are mostly aimed at realistic three-dimensional face models. For three-dimensional cartoon face models, how to use a single photo to generate cartoon textures and make the three-dimensional cartoon faces with the textures have better The overall effect of the problem is extremely challenging
