摘要
在航空图像中提取道路信息具有十分重要的军事和民用价值。利用航空图像中道路与背景之间通常存在着灰度差异,结合数学形态学知识,提出了一种基于数学形态学细化的线性跟踪选择算法,并对算法进行了详细描述和算法优点分析,通过实验验证了算法的有效性,实验证明所设计的线性跟踪选择算法检测效率较高,参数易于选择,道路提取效果好,具有较高的应用价值。
Road extraction from aerial images shows increasing significance of military and civilian, usually, there is diffefence in the brightness of road and background in aerial images. In this paper,a track -selection algorithm based on mathematical morphological thinning for road detection in aerial images is introduced, the algorithm is described and the merits of algo- rithms are analyzed,and the validity of algorithm is validated by experiment. It indicates that the algorithm for road detection has merits of high detection efficiency,parameter is easily selected and has value in practice.
