Abstract

A 3D model appearance texture extraction method and a 3D model appearance texture extraction device of the invention relate to the technical field of 3D models. The method comprises the following steps: getting a preset initial proxy model, and getting a 3D input image input by a user; registering and fitting the initial proxy model according to the 3D input image and the initial proxy model to form a fitted proxy model; and performing intrinsic image decomposition on the 3D input image according to the fitted proxy model, generating the geometric shape of the 3D input image after intrinsic image decomposition and the albedo information of the 3D input image, and determining the secondary geometric texture and the material texture of the 3D input image. The secondary geometric texture and the material texture are appearance textures to be extracted. The problem that it is hard to realize fast and effective extraction of the appearance textures of a 3D model in the prior art is avoided.

Description

technical field [0001] The invention relates to the technical field of three-dimensional models, in particular to a method and device for extracting 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] There are many meth...
