Abstract:

在前人研究基础上,提出了一种基于SPOT5图像和DEM数据自动提取泥石流的方法。首先利用归一化差值植被指数(NDVI)、归一化差值土壤亮度指数(NDSI)和图像经主成分变换得到的第一主成分(PC1)等3种遥感指数获取新的主成分变换图像,进而利用阈值自动选取算法提取包含泥石流的裸地信息;然后基于1:10000的DEM数据,利用改进的沟谷中心线提取算法提取沟谷中心线,并利用数学形态学滤波算法生成沟谷范围;最后将提取的疑似泥石流图斑与沟谷范围匹配,并对矢量化后的结果进行面积、坡度和顺坡性等筛选,得到泥石流或潜在泥石流信息。实验表明,本文构建的泥石流提取模型具有较高的提取精度和效率。
