Terra Drone has conducted a long-distance power line inspection for the Electricity Generating Authority of Thailand (EGAT) and a power energy distributor in Poland.
It completed 12km of power line mapping in a day as part of a mission to research the distance between power lines and the surrounding vegetation.
It also created a detailed tree-trimming report and in turn, provided them with high-quality images of power line with about 1 cm GSD.
The work was carried out with a fixed wing RTK drone equipped with a Sony RX1R I.
Several flights with a maximum flight time of 60 minutes per flight completed a power line inspection with a distance of 50km in total.
Terra Drone uses its in-house 3D power line-recognition algorithm to process the data acquired from the flights.
Through this method, the company claims it could acquire 3D mapping data and a detailed report to allow infrastructure inspection and management to be much more accurate compared to the conventional visual inspection done by helicopter.
The firm went on to confirm that it will continue to help infrastructure owners manage power lines and vegetation in the future.
