近年来，人们对利用遥感技术调查电力线外围的方法进行了一些研究。在使用无人机(UAVs)的测量方法中，正在研究的方法是由无人机拍摄电力线周围的环境，并通过重建电力线和植被之间的三维(3D)点云来进行分离测量。这种方法目前依赖于重建电力线，因此需要从靠近电力线的位置获取图像。然而，通过使用电力公司提供的关于塔架的位置和结构以及电力线的垂度的信息，可以在不进行3D重建的情况下计算电力线的位置。在这项研究中，利用无人机在不同时间获得的数据和传输设备上的信息，实现了对输电线路周围植被的时间序列管理。(C)2020年日本电气工程师学会。由威利期刊有限责任公司出版。
In recent years, several studies have been performed on methods of investigating the periphery of power lines using remote sensing. Among the survey methods using unmanned aerial vehicles (UAVs), those methods are being studied wherein the environment around power lines is photographed by a UAV, and separation measurements are performed by reconstructing the three-dimensional (3D) point cloud between power lines and the vegetation. Such methods currently rely on reconstructing the power line, making it necessary to acquire images from a position close to the power line. However, by using information available from the power company on the position and structure of pylons and the sag of power lines, it is possible to calculate the position of the power line without 3D reconstruction. In this study, time series management of vegetation around power lines was enabled using the data obtained by UAVs at different times and information on the transmission equipment.
