Abstract

Unmanned Aerial Vehicle (UAV) photogrammetry offers significant advantages in efficiency and flexibility for urban 3D modeling, yet balancing accuracy and efficiency remains a critical challenge. Advances in UAV flight stability, sensor accuracy, and data processing algorithms are ongoing. By optimizing flight paths, enhancing sensor performance, and employing data fusion techniques, higher accuracy and efficiency can be achieved. However, issues such as flight safety, insufficient standardization of data processing, and an incomplete quality control system still constrain its development. Future progress requires further optimization of the technical system and improvement of quality control to promote the widespread application of UAV photogrammetry in urban 3D modeling and provide strong support for smart city construction.
