| 摘 要： | 为在高分辨率遥感图像上准确识别地面塌陷、圈定其边界、提取其面积,总结了地面塌陷遥感影像识别标志,提出了一种边界提取方法。该方法以GeoEye高分辨率遥感图像为数据源,在图像融合的基础上,首先用Robert算子和方向算子对融合图像进行边缘增强;然后分别选择原始图像和上述2种边缘增强图像的第一波段进行假彩色合成(Original,Robert and Direction enhanced image,ORD);最后利用ArcGIS软件圈定地面塌陷的边界并提取其相关参数。研究结果表明,该方法可以有效地突出地面塌陷边界,提高其面积提取的精度。

| Abstract: | In order to extract surface collapse's boundary and calculate its area precisely,this paper summed up the identification keys to hazards and introduced a method for extracting the boundary of surface collapse.In this method,high resolution remote sensing image is used as the data source.Based on image fusion,the authors applied the Robert and Directional operators to the fused image respectively.Next,the first band in the original and two enhanced images were used to form false color image(Original,Robert a... |
