Abstract:

The improvement of the accuracy of Structure-from-Motion photogrammetric products is discussed in this paper. In most cases it depends on the number and distribution of ground control points (GCPs) for block orientation, although the placement and precise measuring of GCPs are often time-consuming in a UAS project. This paper presents the evaluation of two approaches including Post Process Kinematic (PPK) and Network Real Time Kinematic (NRTK) methods aiming to avoid GCPs establishment, taking advantage of a real time positioning service, where differential corrections are sent from a network of Reference stations directly to the UAS.
