Delaunay三角网约束下的影像稳健匹配方法
数字摄影测量 影像匹配 Delaunay三角网 线段描述子
2020/5/11
影像匹配是数字摄影测量和计算机视觉领域的关键问题。本文主要研究基于Delaunay三角网约束下的稳健影像匹配方法。首先利用Delaunay三角网对随机初始匹配点进行组织，构建分布均匀、结构稳定的局部连接关系；其次利用线段描述子和空间角度顺序建立了局部辐射和几何约束模型，并将粗差剔除问题转换为分析Delaunay三角网和对应匹配图的相似性问题；然后利用对应三角形局部约束实现匹配扩展；最后在分层策略和...

The general idea that a Delaunay TIN (DT) is more appropriate than non-Delaunay TINs, due to ‘better’ shaped triangles, might be true for many applications, but not for height dependent analytical que...
