一种两点间直线搜索的输电线检测方法

在无人机应用于输电线巡检背景下,为了方便后续的输电线故障检测与分析,提出了一种两点间直线搜索的输电线检测方法。首先,通过方向可控滤波器对无人机图像进行分割。然后,通过所提出的基于圆搜索(CBS)直线段检测方法进行直线段检测。最后,通过所提出的连接算法进行直线段连接。通过在人造图像上的直线段检测实验,证明该方法是一种有效的直线检测方法。随后,通过在实际场景的无人机图像上进行实验,证明该方法是一种有效的输电线检测方法。

A power line detection method based on straight line search between two points

In the background of the application of UAV to the power line inspection, a power line detection method based on two point line search is proposed in order to convenient analyzing the power line. Firstly, the UAV image is segmented by the Canny filter or the Steerable filter. Then, a straight line segment detection method based on the CBS line segment detection method based on image geometric relationship is proposed. Finally, we connect the straight line segments through the proposed join algorithm. Experiments on straight line segments on artificial images show that the method is an effective line detection method. Subsequently, experiments on UAV images in real scenes prove that this method is an effective method for detecting power lines.
