Appearance texture synthesis method and device for three-dimensional model

Abstract

The invention provides an appearance texture synthesis method and device for a three-dimensional model and relates to the field of three-dimensional model technology. The method comprises the steps that global geometric features of an appearance texture model, global geometric features of the three-dimensional model and similarity information of the appearance texture model and the three-dimensional model are determined; first-stage geometric texture enhancement is performed on the three-dimensional model to generate a first-stage geometric texture enhanced three-dimensional model, and a geometric feature map is determined; appearance and material cross-correlation synthesis is performed under the guidance of the geometric feature map to generate synthesized geometric texture and synthesized material texture; second-stage geometric texture enhancement is performed on the first-stage geometric texture enhanced three-dimensional model according to the synthesized geometric texture to generate a second-stage geometric texture enhanced three-dimensional model; the synthesized material texture is applied to the second-stage geometric texture enhanced three-dimensional model, and rendering is performed to obtain an appearance texture synthesis result of the three-dimensional model. Through the appearance texture synthesis method and device, the problems that in the prior art, appearance texture is not truthful visually, and appearance texture information cannot be captured sufficiently can be solved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional models, in particular to a method and device for synthesizing appearance textures of three-dimensional models. Background technique [0002] At present, the appearance texture information (geometric texture and material texture) of a 3D model is an important factor for its visual authenticity. Today's high-end computer games and movie special effects place a great demand on high-precision 3D models with realistic appearance. However, making such 3D models is time-consuming and labor-intensive even for experienced professional modelers. In order to make a high-precision 3D model with rich appearance and texture, modelers often need to use some pictures as creative sources or references. Today's great application and easy availability of digital images also enable computer artists to easily build their image material library as a creative source and reference. [0003] The current 3D mo...
