航空影像特征匹配研究

Feature-based Image Matching for Aerial Images

  • 摘要: 基于格网和三角网的优点,提出了一种基于特征的影像松弛匹配方法。算法利用边缘提取算子提取影像特征信息,把提取的边缘特征点分配到预定的规则格网中进行登记,同时构建特征三角网。

     

    Abstract: Image edges are extracted with a simple algorithm,and the key points of edges are registered in grids.Then for every key edge point,several matching candidates are searched by finding the peak of correlation coefficients,and the initial matching probabilities are calculated with these coefficients.Last,a relaxation optimization algorithm is used to adjust the matching probabilities.From experiments,it can be concluded that the feature-based image matching can improve the accuracy and robustness.
