基于结构特征的军用机场识别与理解

Recognition and Understanding of Airfield Based on the Structure Feature

提出了军用机场结构特征的提取、识别与理解方法 .首先对军用机场图像进行分割、细化、断线自动修补和毛刺分枝自动删除等处理 ,提取出机场的线状几何结构 ;然后根据机场主、辅跑道的平行直线特征 ,与它们之间相连的道路一起构成“日”字、“目”字等结构特征 ,识别出军用机场 ;最后根据机场中各设施的几何结构关系识别并理解它们 .

A method of the structure feature extraction, recognition and understanding for airfield is proposed. The linear geometric structure of airfield is extracted after the airfield image is segmented, thinned, broken lines and burr branches deleted. The airfield is recognized according to the parallel lines structure features of main and additional runways and structure feature of Chinese “ri(sun)”, “mu(eye)” words consisting of the runways and the paths connecting with them. The geometric structure relationship of various facilities in airfield is finally understood. The experiments show that this method can accurately recognize airfield and understand the various facilities in it.
