| 摘 要： | 针对遥感图像的特点,提出了一种遥感图像中机场跑道的提取方法.该方法利用数学形态学对遥感图像进行增强,然后采用最大类间方差选取阈值进行阈值分割,再提取机场连通域,最后经细化后对图像进行两次Hough变换提取跑道.首先对图像进行粗提取得到跑道区域,再对跑道区域进行细提取得出机场跑道.实验结果表明,该方法能够准确提取遥感图像中的机场跑道.

| Abstract: | Aiming at the remote sensing images,a method of extracting airfield runway in remote sensing images is proposed.In this method,mathematical morphology is used firstly to enhance the airport images;secondly the maximum between-cluster variance threshold selection is used to segment the image;and then,the connected component of the airport is extracted.Finally,after thinning,the runway is extracted with the Hough Transform two times.For the first time,the runway region is extracted;for the second time,the runways are acquired.Experimental results show that the method can extract the airfield runways in remote sensing images exactly. |
