| 摘 要： | Hausdorff距离是用于二值图像比较的一种有效的相似度量。利用Hausdorff距离作为图像差异的度量进行地形匹配的算法，首先，提取地形结构线作为特征，计算Hausdorff距离，Hausdorff距离的最小值对应最佳匹配。实验结果表明该算法是有效的。

| Abstract: | The Hausdorff distance between planar sets of points is known as a good method to compare binary images. We present an algorithm to match terrain using the modified Hausdorff distance as the measure of the difference between two images. The terrain structural lines is obtained; then the Hausdorff distances are computed; finally the Husdorff distances is compared. The minimal Hausdorff distance means the best matching result. The experimental result shows that the proposed method is effective for matching terrain. |
