摘要(Abstract)：

针对多视影像重叠度高、影像来源丰富等特点,提出了一种基于多视角影像的纹理择优映射算法,该方法对模型三角形进行逐个相机场景可见性分析,对模型在场景中不可见三角形和部分可见三角形进行选择性剔除,只对完全可见三角形及符合阈值计算的部分可见三角形提供候选纹理三角形,能有效解决模型不可见三角形和部分可见三角形被误贴纹理的问题,再通过对候选纹理三角形的视角分析,为几何模型表面三角形选择一个理论最优纹理,计算映射关系自动映射到模型表面。同时,本文将该纹理择优映射算法应用到基于近景影像的三维重建中,使用从运动中恢复结构SFM的方法进行相机标定及影像相对定向,通过CMVS/PMVS密集匹配方法从影像中获取点云模型,采用Possion算法重构模型三角网,最终利用提出的纹理择优算法确定最佳纹理并实现自动映射。通过与Smart3d、PhotoScan、lensphoto软件的对比证明了本文三维重建及纹理择优算法在近景影像三维重建中的有效性。
