3D MODELLING PERFORMANCE AND USAGE AREA ANALYSIS OF POPULAR UNMANNED AERIAL VEHICLES IN THE SURVEYING AND MAPPING INDUSTRY
 
3D realistic models are used in many fields such as engineering, archaeology, and city planning. The most effective technique used to create these models is the photogrammetry technique. The hardware and software features of the unmanned aerial vehicles to be used to implement this technique are of great importance. Many unmanned aerial vehicles can be used for photogrammetric studies in the industry, and therefore users have difficulties choosing needed unmanned aerial vehicles for their studies. In this study, 3D modelling performance and usage areas of popular unmanned aerial vehicles used in the surveying and mapping industry were examined. For this, a business center building located in an area of approximately 10,771 m^2 was chosen as the study area. To create the building model, 6 ground control points were placed in the study area, and oblique RGB and thermal aerial photographs were taken with 7 different unmanned aerial vehicles. Using photogrammetry software, 3D textured RGB and thermal models were created with each unmanned aerial vehicle data. As a result of the analyses made by considering criteria such as positional accuracy, model quality, and cost, it has been recommended that the DJI Mavic 3 Enterprise model unmanned aerial vehicle with 2.1 cm horizontal and 5.9 cm vertical root-mean-square error is the optimum model that can be used for 3D modelling purposes. In addition, DJI Matrice 30 Thermal is recommended for thermal applications, and the WingtraOne Gen II model is recommended for large-scale city modelling projects.
