dc.description.abstractGlavni fokus rada je procjena kvaliteta 3D modela terena dobijenih iz snimaka bespilotnih letjelica (UAV). Kvalitetni i detaljni modeli terena neophodni su, prije svega, za precizno određivanje promjena na području iskopa zemljišta. Analiza kvaliteta 3D modela uključuje stepen odstupanja geometrijskih i geomorfoloških karakteristika od stvarnog položaja terena i statusa u prirodi. Za određivanje geometrijske tačnosti primjenjuje se uporedni način ispitivanja, odnosno poređenje izmjerenih vrijednosti 3D modela sa podacima dobro definisanih geodetskih i kontrolnih tačaka a posteriori mjerenih primjenom Globalnih Navigacionih Satelitskih Sistema (GNSS). Analiza kvaliteta i poređenja se obavljaju vizualno, numerički, sračunavanjem zapremine iskopa i izradom profila terena. Rezultati sugerišu da su 3D modeli dobijeni iz snimaka UAV-a veoma kvalitetni. Takođe, važna prednost korišćenja slika UAV-a za generisanje 3D modela na području iskopa je njihova efikasnost, na primjer, češće ažuriranje i mjerenje visina nepristupačnog terena i određivanje lokalnih promjena na terenu.
dc.description.abstractThe main focus of the paper is the assessment of the quality of the 3D terrain models obtained from the images of unmanned aerial vehicles (UAV). Quality and detailed terrain models are necessary, above all, for precise determination of changes in the area of excavation. The quality analysis of the 3D model includes the degree of deviation of geometric and geomorphological characteristics from the actual terrain position and status in nature. To determine the geometric accuracy, a comparative method of testing is used, ie a comparison of the measured values of the 3D model with the data of well-defined geodetic and control points a posteriori measured using the Global Navigation Satellite Systems (GNSS). Analysis of quality and comparisons are performed visually, numerically, by calculating the excavation volume and creating a terrain profile. The results suggest that the 3D models obtained from the UAV images are of very high quality. Also, an important advantage of using UAV images to generate 3D models in the excavation area is their efficiency, for example, more frequent updating and measuring the height of inaccessible terrain and determining local changes in the terrain.
