| 摘 要： | 提出了一种利用空间拓扑模型自动检测居民地变化类型的方法。在新正射影像与旧矢量数据配准的基础上,把已有的居民地范围作为样本区域,利用Law的能量模板和纹理谱进行影像分割,提取新的居民地边界,运用空间分析的方法自动检测出居民地的6种变化形态。实验结果证明了此方法的可行性和有效性。

| Abstract: | A new method is proposed for automated recognzing the change types of residential areas using topological relations between new and old boundaries of residential areas.The residential areas samples on new rectified images are selected by existed boundary of residential areas on old maps.In order to obtain correct ranges of residential areas on the new rectified images,a two-step algorithm is applied.The first step is to do initial extraction of residential areas based on Law's Temples.The second step is to adjust the initial results using Grain table.To recognize the six change types of residential areas,the topology relations of new boundary on the rectified images and old boundary on the existed maps are analyzed by a 4-intersection model.The experimental results show that the proposed method using topology relations can automatically identify the change types of residential areas and provide more accurate change information. |
