Ocena višinske točnosti DMR iz posnetkov iz letalnika : diplomska naloga

Zaviršek, Marko (author), Pavlovčič Prešeren, Polona (mentor), Grigillo, Dejan (comentor)

V diplomski nalogi smo ocenili višinsko točnost DMR, izdelanega iz fotografij, zajetih z letalnikom DJI Phantom 4 Pro. V prvem delu diplomske naloge smo opisali določitev oslonilnih točk s hitro statično metodo izmere GNSS, zajem detajlnih točk z elektronskim tahimetrom in zajem fotografij z letalnikom. V drugem delu diplomske naloge smo predstavili postopek obdelave fotografij in ocenili višinsko točnost izdelanih DMR. Ugotovili smo, da je povprečno višinsko odstopanje izdelanega DMR pod 1 cm, višinska točnost DMR pa približno 2 cm.

• Title: The evaluation of height accuracy on the basis of the recordings from the drone : graduation thesis

Abstract

In the bachelor’s thesis, we evaluated the height accuracy of digital terrain model (DTM), made of photographs recorded by the drone DJI Phantom 4 Pro. In the first part of the thesis, we described the determination of ground control points with the rapid static method GNSS measurement, recording of the detailed points with an electric tachometer, and the recording images by drone. In the second part of the thesis, we presented the procedure of processing of the images. We evaluated the height accuracy of the produced DTMs. We have found that the mean height error of the produced DTM is below 1 cm and the DTM accuracy is approximately 2 cm.
