Abstract

Na točnost fotogrametričnega bloka vpliva število oslonilnih točk, uporabljenih v izravnavi bloka. V nalogi smo preverili, če je možno z letalnikom, opremljenim s sprejemnikom GNSS RTK, ki omogoča izmero položaja senzorja na letalniku v realnem času, in inercialno mersko enoto, doseči primerljivo točnost fotogrametričnega bloka z manj oslonilnimi točkami kot z letalnikom, ki tega sprejemnika nima. Na območju izmere smo vzpostavili geodetsko mrežo točk z visoko položajno natančnostjo, ki so predstavljale oslonilne in kontrolne točke. Izbrani fotogrametrični blok smo dvakrat obravnavali. Pri prvi obravnavi smo upoštevali meritve RTK sprejemnika, pri drugi teh meritev nismo upoštevali. V vsaki obravnavi smo naredili več izravnav fotogrametričnega bloka. V izravnavah fotogrametričnega bloka smo upoštevali različno število oslonilnih točk. V analizi smo primerjali točnosti fotogrametričnega bloka z uporabo različnega števila oslonilnih točk.

Secondary title: Influence of the number of ground control points on the accuracy of the photogrammetric block
Secondary abstract: The positional accuracy of photogrammetric block is influenced by a number of ground control points used in the adjustment. In the thesis we checked if it was possible to achieve comparable accuracy of the photogrammetric block with fewer ground control points between an unmanned aerial vehicle (UAV) equipped by GNSS RTK receiver and IMU (Inertial measurement unit) and an aircraft without such equipment. The area where we made measurements was established by a geodetic network of points, which represent the ground control points and check points in the adjustment of the photogrammetric block. The selected photogrammetric block was examined twice. Firstly we considered the RTK measurements, yet the second time we did not take those into consideration. During the adjustment of the photogrammetric block we considered different numbers of ground control points. The accuracy of the photogrammetric block in which we considered RTK measurements was later compared with the accuracy of the photogrammetric block where the RTK measurements were not considered. In each case of the adjustment we used a different number of ground control points. In the analysis, we compared the accuracy of the photogrammetric block using different numbers of ground control points.
