| 摘 要： | 针对近景影像自动相对定向过程中初匹配点对中误匹配率较大的情况,将基于三角形约束方法引入近景影像匹配.首先利用Harris算子提取特征点集,经初匹配后运用基于RANSAC方法和P-H算法的相对定向构建核线几何得到内点集,删除误匹配点生成同名Delaunay三角网；在同名三角形的约束下通过缩小Harris特征点阈值得到新内...

| Abstract: | A new image matching method is introduced based on triangle constraint into the process of automatic relative orientation of close-range imaging considering the large proportion of outliers.Firstly,this method used an algorithm for Harris corner detection to extract the keypoints,then the RANSAC method and pope-hinsken algorithm were led into the process of relative orientation to construct the epipolar geometry after the initial matching.Secondly,it triangulated the well-defined inliers based on the Delaun... |
