Fast stereo edge-matching algorithm based on corner-guidance

  • 摘要: 提出了一种新的基于角点引导的快速立体边缘匹配方法.在匹配过程中,为了保证其快速性引入了两种新约束:角点约束与边缘约束.首先,利用匹配的角点信息引导边缘的匹配,对如何利用已匹配的角点引导边缘匹配进行了详细的阐述,同时,在引导过程中提出了只利用8个方向的区域扩张方法,进一步保证快速性.其次,提出边缘约束实现点与点的匹配,使搜索范围仅限制在几个像素内,再利用极线约束实现点的匹配,必要时可结合灰度相关约束.结果表明:该算法取得比较好的匹配效果,引入的两种约束在很大程度上提高了速度和正确率,边缘点匹配的正确率高达97%以上.
