摘　　要：针对可见光遥感图像中的机场跑道检测问题,提出了一种基于方向预判的局部Hough变换方法。通过频谱能量楔向采样,确定频谱图中对能量贡献起主导作用的系数分布角度范围与机场跑道的对应关系,得到跑道的方向预判结果;利用方向信息对Hough变换角度的取值范围进行压缩,通过局部Hough变换进行直线检测得到机场跑道。实验结果表明:该方法能够较好地消除复杂背景中地物的干扰,快速准确地检测出机场跑道。In this paper, a local Hough transform method based on direction prediction is proposed for the airport runway detection of visible remote sensing image.The runway direction prediction is achieved by determining the correspondence between the coefficient distribution angle range with a dominant function in energy contribution and the airport runway.With the use of the direction information of the runway, Hough transformation range is reduced, and the airport runway is obtained via the line detection through local Hough transformation.Experiments show that, with this method, the disturbance from the ground objects in complex background can be better removed, and the airport runway can be detected with great speed and accuracy.
