Process of tree barrier modeling Time of process of traditional tree barrier modeling Time of tree barrier modeling by image recognition of transmission tower based on big data
Taking tilt photography photos of transmission lines The speed of fixed-wing UAV is 28 m/s, and the flight distance is twice of the transmission line [30] The speed of fixed-wing UAV is 28 m/s, and the flight distance is twice of the transmission line
Image recognition of transmission tower about 5 min within 10 s
Generating power lines 3 min per line span 2 min per line span
Point cloud classification about 35 min for 400 m line span about 35 min for 400 m line span
Measuring the distance between trees and wires 1 min per line span 1 min per line span
