Fast power line detection in images is useful in photogrammetry applications such as measuring wire tension and sag. To make these measurements, images of entire power line spans must be used which may include large amounts of curvature. Previous work in power line detection has focused on aerial or close proximity images where no power line curvature is visible. This paper assesses feasibility of ground-based imaging utilising smartphone cameras together with fast and robust power line detection using two common Hough transform techniques, and a line tracing algorithm.
