V raziskovalnem delu obravnavamo UAV inšpekcijske preglede na premostitvenem objektu – viaduktu Slatina. S SfM/MVS fotogrametrijo in terestričnim laserskim skeniranjem smo izvedli meritve za namene inšpekcijskih pregledov. Na podlagi meritev smo izdelali oblake točk, digitalne modele površja in ortofote. S primerjavo oblakov točk terestričnega laserskega skeniranja in UAV fotogrametrije smo analizirali prisotnost šuma v fotogrametričnem oblaku točk. Analizo primernosti ortofotov za namene UAV inšpekcijskih pregledov smo naredili s primerjavo ortofotov stebra viadukta z različno prostorsko ločljivostjo.

Abstract

In the research work, we analyse UAV inspections on the bridge facility - the Slatina viaduct. With the SfM/MVS photogrammetry and terrestrial laser scanning, we perform measurements for inspection purposes. Based on the comparison of point clouds of terrestrial laser scanning and UAV photogrammetry, we analyzed the presence of noise in the photogrammetric point cloud. We analyzed the quality of orthophotos for the purposes of UAV inspections by comparing orthophotos of the viaduct pillar with different spatial resolutions.
