3D Mapping with UAV:
Procedure Analysis and Performance Evaluation with Field Tests


Due to the technical advancement of both computer hardware and software, the Unmanned Aerial Vehicles (UAVs) have the ability to provide alternative solution for surveyors to acquire 3D coordinates of ground objects, other productions include orthomaps, DSM/DTM, 3D model, etc. Compared with other techniques such as RTK GPS, total station survey and terrestrial laser scanner, itís a more productive and cost-effective method. This thesis project will reveal the background knowledge associated with UAV mapping; demonstrate the UAV mapping procedures including camera calibration, flight planning, data acquisition as well as image processing; display some of the most important productions; estimate the accuracy of UAV mapping and evaluate the influences of different factors on the results, influence factors such as the distribution and numbers of GCPs, flying heights, as well as software packages will be considered and analysed. The project establishs an optimized UAV mapping procedure, provides the feasibility of UAV use for surveying and mapping applications and proposes some possible improvements in the future as well as indicates whether UAV could be an alternative surveying and mapping solution to the current ground-based surveying techniques.
