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。
Based on the skeleton representation of the runway area, skeleton skeletal motifs are detected from the skeletal map, the saliency measures of the branch motifs are calculated, and the adjacency relationships between the branch motifs are established. According to the geometric characteristics of airport runway area, the spine primitives are used to represent the stripe regions. The width, length and direction information of the spine primitives are taken as the salient measure of spine elements. With prior knowledge, Yuan, identify the main runway. Select an airport remote sensing image as an experimental analysis to verify the feasibility of the algorithm.
