Domain Adaptation in Power Line Segmentation: A New Synthetic Dataset

Power line segmentation is a critical component of UAV intelligent inspection systems to ensure the safe and reliable operation of power grids. For challenging-to-label tasks like this, simulators can efficiently generate large amounts of labeled data. In this work, a large-scale annotated synthetic power lines dataset generated utilizing the unity game engine and the unity perception package ¹. To address domain shift between real and synthetic domain, input-level adaptation performed. Additionally, a new power line segmentation loss developed to mitigate the effects of unbalanced pixel distributions among power lines and background. Experiments demonstrate that our approach achieves state-of-the-art performance on power line segmentation task.
