3D Reconstruction of Power Lines Using UAV Images to Monitor Corridor Clearance

Article

Full-text available

Nov 2020

Regular power line inspections are essential to ensure the reliability of electricity supply. The inspections of overground power submission lines include corridor clearance monitoring and fault identification. The power lines corridor is a three-dimensional space around power cables defined by a set distance. Any obstacles breaching this space sho...

Accuracy Evaluation of Real-Time GNSS Precision Positioning with RTX Trimble Technology

Article

Full-text available

Dec 2018

In this paper, authors present results of accuracy verification of the Trimble RTX technology. The GNSS receiver Spectra Precision SP60 was used in Cyprus (Kato Paphos Archaeological Park). To evaluate the accuracy of the receiver, two measuring test networks (consisting of 30 and 55 control points) were established. All points were determined in f...

Czasoprzestrzenna analiza stanu osuwiska w Kłodnem, gmina Limanowa [Space-time analysis of the condition landslide in Kłodne village, Limanowa municipality

Conference Paper

Apr 2016

W 2010 roku w południowej części Polski wystąpiły intensywne opady atmosferyczne, które przyczyniły się do powstania lub odmłodzenia wielu osuwisk. Jedno z nich powstało we wsi Kłodne (gmina Limanowa). Od marca 2013 roku pracownicy oraz studenci AGH w Krakowie prowadzą okresowy monitoring geologiczny i geodezyjny. W pierwszym etapie wykonano kartow...
