Research on Fine Modeling and Visualization of UAV Tilt Photogrammetry

Unmanned aerial vehicle tilt photogrammetry has the characteristics of high efficiency and low cost in large-scale 3D modeling applications, but this method is prone to problems such as voids and scratches when displaying individual models. This article analyzes the factors that affect the accuracy of 3D models, and uses multi-scale oblique photogrammetry methods to achieve precise modeling and visualization of individual buildings.
