"A Practical Guide to UAV Mapping Production Line"


Unmanned Aerial Vehicles (UAV)s used for mapping applications face many problems. This is mainly because they carry nonmetric cameras which suffer from high geometric and radiometric distortions. This course aims at explaining the principles and challenges of using UAV photogrammetry for mapping applications. Not only the theoretical aspects but the practical procedures of conducting a typical project are discussed.

The topics included, but not limited to, are in two parts. Part I is an introduction to UAV photogrammetry and its role in mapping, components of a UAV, challenges of a UAV photogrammetry project, and its time and cost issues. In the part II, stages of a typical UAV Photogrammetry project are practically presented including planning issues such as GSD definition, flying height and overlap setting, GCP design with/without aerial kinematic GNSS observations. Then image acquisition with emphasis on permissions and safety issues, camera parameters settings and all things to check before the flight are presented. For processing step, some issues such as choosing the right hardware, aerial triangulation (observation weights, blunder detection and quality improvement) are studied. In continue, DEM and Ortho-photo generation and 2D versus 3D stereo plotting are presented.
