| 摘 要： | 基于嫦娥一号CCD数据的空间特征,开展月球表面陨石坑和线性构造目标识别的探索研究。利用图像边缘检测算法将影像分割成许多目标体;为了解决过度分割和错分问题,根据分割结果对分割后的目标体进行合并;为获取地质意义和语义信息更丰富的陨石坑和线性构造目标,将合并结果导入ArcGIS进行手动修改。最后,以影像数据的空间特征为基础,基于规则分类原理,根据研究需要设定不同的识别规则,进行陨石坑和线性构造的自动识别,取得了较好的效果。

| Abstract: | Based on spatial features,the authors identified preliminarily impact craters and linear tectonics by using Chang'E-1 satellite CCD data.First,many targets were segmented by using the edge detection method and then merged in order to reduce excessive and wrong segmentations.Second,the merging result was manually updated by using ArcGIS software so as to obtain geologically significant information.Finally,different identification rules were proposed for identification of impact craters and linear tectonics b... |
