摘要
本文针对机场跑道成像的线状结构和高灰度值的特征,提出了一种从SAR图像中检测机场跑道的方法。具体介绍了用跑道特征检测算子检测跑道边缘和基于边界跟踪的直线提取方法。实验结果表明,该算法有效地克服在边缘检测和直线提取过程中的噪声影响,提高了检测的速度和准确性。
Based on analyzing the runway characters of linear structure and high intensity,a algorithm to detection runway from SAR image was presented in this paper. Edge detection with the runway feature detector to obtain the edge of runway and extracting straight lines according to Edge-tracing were introduced. The experimental result showed that the algorithm could overcome the influ- ence of yawp in edge detection and extracting straight lines, expedited the speed, enhanced the veracity.
