3D Texture Pattern Synthesis Method Based on Dragonfly Visual Imaging Model Setting

Abstract

The invention discloses a three-dimensional texture pattern synthesis method based on dragonfly vision imaging model setting. The method comprises the steps that the two-dimensional texture patterns of the three-dimensional space under three different illumination angles are acquired; a dragonfly vision imaging model is established; multiple hexagonal texture pattern feature matching regions are set and aggregated into the three-dimensional texture patterns; a three-dimensional texture pattern feature matching function is set for performing image feature matching so as to perform three-dimensional texture pattern feature inputting and output the three-dimensional texture pattern matching features to perform matching; the optimal three-dimensional texture pattern feature matching distribution and the distribution region are set; three-dimensional texture pattern style setting is performed on the three-dimensional texture pattern style feature change; and feature matching optimization isperformed and the set three-dimensional texture patterns are synthesized. The three-dimensional texture pattern feature matching detail features are ensured not to be lost, the texture pattern features are continuous and the continuity and texture patterns of the three-dimensional texture pattern features can be greatly saved.

Description

technical field [0001] The invention belongs to the fields of computer vision and image processing, and in particular relates to a three-dimensional texture pattern synthesis method based on a dragonfly vision imaging model. Background technique [0002] When setting and matching 3D texture patterns, rich 3D textures are often required to enhance the realism of the scene. However, the three-dimensional texture patterns that people can actually obtain are very limited, and it is difficult to meet the needs of society's texture scene synthesis. How to automatically set a large number of 3D texture patterns required for realistic 3D texture patterns has become an important research and application problem in graphics. [0003] The 3D texture pattern synthesis method focuses on research: 3D texture pattern feature matching under different lighting conditions and viewing angles, 3D texture pattern synthesis and rendering of 3D texture patterns; using 3D texture models and geomet...
