Abstract
For safe transmission of electricity, it is necessary to determine the separation between transmission lines and forests around steel transmission towers. Unmanned aerial vehicles (UAVs) have low operational costs, and UAV image data are of high resolution that can be acquired at any arbitrary time. Therefore, to reduce the cost of determining the separation between transmission lines and forests, UAV data can be utilized for three-dimensional (3D) reconstruction of the transmission lines and forests. In this study, we developed a method for measuring the separation between transmission lines and forests using such a 3D reconstruction.

Summary
Electricity is an important utility in our daily life. Power transmission lines for transporting electricity have the following characteristics: (i) high voltages of 11.2 kV or more, (ii) supported by steel transmission towers, and (iii) several of them are placed in mountainous areas. On August 14, 2003, a major blackout occurred across parts of Canada and the United States[1]. The blackout reached 61,800 MW and affected approximately 50 million people. Complete recovery took more than a week in some areas. The blackout was caused by tree branches touching transmission lines. It is necessary to determine the separation between transmission lines and forests around steel transmission tower to transmit electricity safely
