Sažetak
Rapid development and increased availability of unmanned aerial vehicles (UAVs) resulted in the exponential use of these systems in many scientific fields and activities. However, the application of photogrammetric models derived using the Structure from Motion (SfM) technique largely depends on the use of ground control points (GCPs). Since the acquisition of the GCPs requires the use of high-quality total stations or GNSS-RTK receivers, these procedures generally take up a lot of time. Execution of a photogrammetric process without using the GCPs is called direct georeferencing, and it is becoming an increasingly popular method. In this research, we tested three methods of RTK positioning using the system of the Matrice 210 RTK V2 and DRTK 2 mobile station. The following methods were tested: (a) D-RTK 2 as a base station ; (b) D-RTK 2 correction with the third-party base station ; (c) network NTRIP corrections CROPOS. An absolute accuracy assessment of each RTK positioning mode was done using 10 check points (CPs). By calculating the total RMSE, it was determined that (b) and (c) RTK positioning modes have a centimeter level of accuracy (<10 cm). In this research, it is determined that the tested UAV system for direct georeferencing can be used in a wide range of geographical applications and other disciplines where absolute accuracy of centimeter- level is required.
