Comparative Analysis Of The Application Of Rtk And Ppk Methods In Uav Photogrammetry Process

Abstract

As part of this master's thesis, a comparison was conducted between two methods of spatial data collection using an unmanned aerial vehicle (UAV): the method involving ground control points (GCPs) and the kinematic method with post-processing (PPK). A complete photogrammetric processing of the collected data was performed, including the generation of point cloud and a digital terrain model. For each method, the accuracy of the obtained results was analyzed, especially in terms of horizontal and vertical accuracy. The obtained data were compared and critically analyzed from the aspect of accuracy, efficiency and applicability in different conditions.
