一种三维数字城市自动纹理映射优化方法
|
摘要
在基于多视影像的纹理映射中,由于各种外界因素导致的影像间色彩的差异会在纹理贴图后产生一些不可避免的纹理接缝。为减少这种纹理接缝现象,在三角网模型选择最优影像后对纹理影像分布进行了优化。介绍了一套完整的纹理映射流程,综合马太效应和贪心算法的策略进行纹理分布优化。实验表明,提出的方法能得到更好的纹理映射效果。
In the multi-view image-based texture mapping, the color difference between the images due to various external factors will produce some unavoidable texture seams after the texture mapping. In order to reduce the texture seams, we optimize the texture distribution after choosing the optimal image in the triangulation model. In this paper, a complete texture mapping process is introduced, and the texture distribution is optimized by combining Matthew effect and greedy algorithm. Experiments show that the scheme proposed in this paper has a better texture mapping result.
