在分析航拍和遥感机场跑道结构特征的基础上,提出了一种结合跑道方向特性的快速识别方法。具体介绍了方向小波变换检测边缘的算法和基于方向特性的改进Hough变换提取直线的方法。前者增加了检测结果的有效性和可靠性,后者加快了跑道识别速度,并能详细描述跑道。实验结果表明本算法是准确、快速、稳健的。

A Speedy Algorithm of Airport Recognition based on Directional Feature of the Runway

Based on analyzing the structure feature of runway in aerial and remote sensing images, a fast algorithm to detecting runway combined with its directional feature was presented in this paper.Edge detection with directional wavelet transform and straight-line extraction grounded upon orientation character were concretely introduced.The former increased the validity and the reliability of the detecting results, and the latter expedited the recognition speed as well as depicted the runway in detail.Experimental results indicate that this method is exact, speedy and robust.
