Wenyu Wang, Yuanjing Liu, Xianpei Wang · 2017
using small commercial UAV equipped with a simple visible light camerato obtain the depth information of power line and the ground through monocular or binocular vision is the focus of the research.And how to use digital image processing method to extract the power linerapidly, accurately, automatically is one of the core issues.Therefore, in this paper, three methods of power line extraction are analyzed, namely, the Hough transform, Radon transform and LSD algorithm, pointing out the problems existing in the three algorithms.Aiming at the problems, a method based on priori knowledge-restrained scope, was proposed, in order to improve the accuracy of the power line detection.The effectiveness of the algorithm is verified by the experiments.
