摘要

提出了一种基于LROC DEM数据的月球地形自动识别方法。该方法将地形因子和纹理特征参数结合在一起,形成特征向量,用于描述不同的月球地形。然后对这些特征向量进行归一化处理,得到更好的分类结果。将归一化特征向量聚类为月母和月高地两类。对近1000个不同地形的DEM数据样本进行了测试,与已知方法相比,新方法的测试结果令人满意,特别是在月海地区,新方法的正确识别率达到了88.29%以上,总体正确识别率达到了95%。

Lunar Terrain Auto Identification Based on DEM Topographic Factor and Texture Feature Analysis
A new auto method to identify the lunar terrain of LROC DEM data has been proposed. The new method combined topographic factors and the texture feature parameter together to form feature vectors for descripting the different lunar terrains of DEM. Then the new method will normalize these feature vectors for getting the better classifying results. Normalized feature vectors would be clustered to two categories, which are lunar mare and lunar highland. The new method has been tested by near 1000 different terrain samples of DEM data and the testing results were satisfied compared with known methods, especially for lunar mare areas, the correct recognition rates of the new method were more than 88.29%, and the overall correct recognition rates of the new method were up to 95%.
