Abstract

The concept of oblique image acquisition entered the literature long after the overhead photogrammetric acquisition techniques. The oblique image acquisition technique is applied to model the edge surfaces of buildings that cannot be obtained with vertical (nadir) image acquisition and eliminate the problems that arise in the orthorectification of high-rise buildings in urban areas. Oblique image acquisition by Unmanned Aerial Vehicles (UAV) independent of aerial photogrammetry is considered possible with unique flight plans. How convenient oblique image acquisition with the help of UAVs is and how it affects the final product is a popular topic studied by researchers. In this study, oblique image acquisition was performed using a rotary-wing UAV (Parrot ANAFI) whose camera can move 180°. With the help of the 3D models obtained, the building was drawn in vector and evaluated to scale. As a result, it has been understood that almost all structural deficiencies in the final products can be eliminated by oblique images. However, it has been revealed that there is still a need for other methods for structures that do not have patterns, such as flat walls.
