| 摘 要： | 提出了一种改进的Hough变换方法用于机场跑道的检测。传统Hough变换存在计算量大等缺陷,本文利用直线边缘的梯度相位信息把Hough变换中θ的取值限定在一个较小的范围内,同时减少用于计算的像素点数,大大降低了计算量。通过实验证明了本文方法切实可行。

| Abstract: | This paper presents a novel approach to the detection of airfield runway, which is based on improved Hough transform. To reduce the computational burden of Hough transform, information of gradient phase of straight lines was used to limit the parameter θ into a small range, which reduces the number of pixels used in transform. By this way, the amount of computation has been reduced. The results of experiment show that this algorithm performs well. |
