Investigation of 3D models acquired with UAV oblique images

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