摘要: 提出了根据同名像点构成三角网 (TIN)来进行同名直线的匹配。依据TIN预测左影像上一条给定直线在右影像上同名直线的搜索范围,计算给定直线与候选直线的灰度相关系数,取最大相关系数所对应的直线为同名直线。实验证明,该算法简单、可行。

Abstract: This paper presents an algorithm to find homonymous line from images based on Delaunay triangulation(TIN). The search range on right image of a given line on left image is decided from TIN. The relation coefficient between given line and selected matching line in search range of right image is computed. The line with the largest relation coefficient is homonymous line.The method is tested feasible.
