A Review of UAV Tilt Photogrammetry Technology for Digital Modeling of Hydropower Station Geomorphology

Unmanned aerial vehicle (UAV) tilt photogrammetry technology is a new technology that uses UAVs to obtain high-definition images, and has fast response data acquisition capabilities. In the hydropower industry, UAV tilt photogrammetry technology can obtain panoramic images, perform aerial monitoring, produce real-life three-dimensional models and achieve engineering calculations, providing intuitive geomorphological analysis and reliable data sources for projects. This paper briefly describes the types and system composition of UAV, and discusses the key technology of UAV tilt photogrammetry for digital modeling of hydropower station landform.
