Abstract

The invention discloses a multi-view texture mapping method. The method can be used for carrying out high-realistic texture mapping on a three-dimensional model by an image sequence shot in multiple angles. The method comprises the steps of firstly converting multi-view texture mapping into a Markov random field problem, and obtaining an optimal texture image corresponding relation of each patch by an energy optimization method; then simplifying mapped texture data, and restoring invalid textures in part of invisible regions; finally eliminating the color difference of spliced boundaries of textures by a gradient merge method, and obtaining a seamless texture mapping effect. Compared with the conventional method, the method disclosed by the invention has obvious advantages in the two aspects of mapping of complicated sheltered textures and merging of large texture data in the model; high-quality texture mapping is still generated in a complicated scene; examples in a series of complicated scenes show the effectiveness and the robustness of the method.

Description

technical field

[0001] The invention relates to a high-quality texture mapping method for a three-dimensional scene, in particular to a high-quality texture mapping method for a complex three-dimensional scene. Background technique

[0002] 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 graphics, texture mapping allows users to collect real natural scene photos as 2D texture data, which is very important for expressing realistic 3D object models.

[0003] Each frame of video captures only a local area of the scene, so multiple frames of video need to be combined to create a complete texture map of the 3D model. Wang Lifeng et al's method (L.Wang, S.B.Kang, R.Szeliski, H.-Y.Shum: Optimal texture map reconstruction from multiple views.In CVPR, 2001.) and Baumberg's method (A.Baumberg:Blending images for texturing 3D models.In BMVC,2002:404–...
