Povzetek

S sodobnim tehnološkim razvojem se razvijajo tudi posamezne veje geodezije kot stroke. Uporaba brezpilotnih letalnikov se je v geodeziji že uveljavila kot eden izmed virov zajema prostorskih podatkov. V diplomski nalogi smo analizirali podatke snemanja istega območja, pridobljene z dvema različnima brezpilotnima letalnikoma v istem dnevu. Ocenili smo kakovost obeh izdelanih vrst ortofota iz teh posnetkov in kakovost digitalnih modelov površja, ki sta bila uporabljena za izdelavo ortofota. Ugotovili smo, da z večanjem števila oslonilnih točk izboljšujemo položajno točnost ortofota. Ocenili smo tudi nekatere vplive na kakovost ortofota in kakovost digitalnega modela površja. Ugotovili smo, da ima zelo velik vpliv na kakovost ortofota in kakovost digitalnega modela površja prostorska ločljivost posnetkov. Posledica slabše prostorske ločljivosti v oblaku točk je bolj posplošena oblika in slabša točnost digitalnega modela površja.

Sekundarni naslov: Analysis of the quality of orthophotos generated from close range aerial images
Sekundarni povzetek: Along with the modern technological developments, also the individual branches of land surveying as a profession are developing. The use of unmanned aerial vehicles (UAV) is in land surveying already one of the established sources of acquiring spatial data. In this thesis, we analyzed the data obtained with two different unmanned aerial vehicles recording the same area on the same day. We evaluated the quality of the both types of the orthophotos that were made from these recordings, as well as the quality of the digital surface models (DSM) that were used for the production of the orthophotos. We found out that the increasing of the number of ground control points (GCP) improves the positional accuracy or the orthophotos. We also evaluated some of the effects on the quality of the orthophotos and the quality of the digital surface model. We found out that the image spatial resolution has a very greate impact on the quality of the orthophotos and the quality of the digital surface model. The consequence of the poorer spatial resolution of point cloud is more generalized and less acurate digital surface model.
