Practical Experience of the Use of RGB Camera Images in UAV for the Generation of 3D Images in the Accurate Detection Distance of Vegetation Risk in Right-of-Way Transmission Line
The Brazilian National Interconnected System has an extensive power transmission grid, where the lines are mostly located far from the urban centers and in difficult access areas. This makes inspection and maintenance more expensive and complex. In this sense, it is important to monitor and apply technological innovations in terms of equipment (sensors, cameras), telecommunication systems and vehicles, which aim at reducing costs, reducing environmental impacts and increasing reliability. This work will investigate the use of 3D modeling of a training transmission line stretch using RGB images captured using sensor coupled in unmanned aerial vehicle. It is a first investigative step for the specific purpose of detecting, with high accuracy, the vegetation along the right-of-way. Exemplifications and conclusions are presented at the end of the paper.
