【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。更多还原

【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.更多还原
