| 摘 要： | 基于骨架对跑道区域进行表示，从骨架图中检测骨架分支基元，计算分支基元的显著性度量并建立分支基元之间的邻接关系。针对机场跑道区域具有的几何特征，采用脊柱基元表示条状区域，将脊柱基元的宽度、长度和方向信息作为脊柱基元的显著性度量，借助先验知识，检测得到主跑道的脊柱基元，识别主跑道。选取一幅某机场遥感图像作为实验分析，验证了算法的可行性。

| Abstract: | By detecting the branches of skeleton image of the main-runway of airport, and computing the notability measurement of them, the adjacent relationship among branches is established. Considering the geometric characters of runway, the rachis element is used to represent the strip-shaped area,and some features such as width, length, and direction of rachis element are employed as notability measurement. The rachis element of main-runway can be detected in virtue of prior knowledge of airport, then the main-runway can be recognized. The processing of the remote sensing image of an airport verifies the feasibility of the algorithm. |
