diplomska naloga
Povzetek
Namen diplomske naloge je ugotoviti vpliv kakovosti koordinat oslonilnih točk na izračun prostornine gradbene jame iz oblaka točk. Oblak točk smo generirali iz fotografij zajetimi z brezpilotnim letalnikom. Koordinate oslonilnih točk smo najprej izmerili z GNSS RTK metodo, ki je hitrejša in manj natančna. Nato smo mrežo oslonilnih točk izmerili z natančnejšo klasično geodetsko izmero. Oceno natančnosti merjenih količin smo naredili po ISO standardu. Koordinate oslonilnih točk smo določili z izravnavo horizontalne in višinske geodetske mreže. Izračun prostornine gradbene jame smo naredili v programu 3D Survey, pri čemer smo uporabili koordinate oslonilnih točk, določene z različnimi metodami izmere. Rezultate izračunanih prostornin smo primerjali med seboj. Razlika prostornin je bila manjša od enega odstotka, kar pomeni, da je GNSS RTK metoda dovolj natančna za georeferenciranje oblaka točk za potrebe izračuna prostornine.

Impact of quality of coordinates of the ground control points to calculate the volume of point clouds close range photogrammetric capture |
Sekundarni povzetek: |
The purpose of this thesis was to determine how the quality of coordinates of the ground control points affects the volume calculation of construction excavation voids calculated from a point cloud. The point cloud was generated based on the photographs taken by an unmanned drone. The ground control points were initially measured using the faster but less accurate GNSS RTK method. Subsequently, we then measured the ground control points using a more precise classical geodetic measurement. The accuracy of the results of these measurements was then evaluated according to the ISO standard. The coordinates of the ground control points were determined by levelling the horizontal and vertical geodetic network. The volume calculation of the construction excavation void was carried out using the 3D Survey software, where the coordinates of the ground control points were defined with various methods of measurement. The volume measurement results obtained were then compared. The results showed the difference in volume amounting to less than 1 percent, proving the GNSS RTK method is accurate enough to be effectively used for georeferencing of a point cloud in order to accurately measure volume. |
