20.500.12556/RUL-150200 Fotogrametrična izmera geodetskih znamenj mariborske triangulacijske baze diplomska naloga št.: 137/TUN Photogrammetric survey of geodetic marks of the Maribor Triangulation Base graduation thesis no.: 137/TUN V diplomskem delu smo izvedli izmero dveh krajnih točk mariborske trigonometrične baze s fotogrametrično izmero. Točki mariborske trigonometrične baze, ki sta bili postavljeni leta 1860, sta sestavljeni iz dveh delov: zgornjega okoli 1,90 m visokega piramidnega dela in spodnjega okoli 1,25 m visokega kvadratnega dela. Severna bazna točka s številko 218 se nahaja na robu Orehove vasi, južna s številko 217 se nahaja na robu vasi Starošince, med njima je 6 km razlike. Oba spomenika smo fotografirali s fotoaparatom in z metodo grajenja strukture iz gibanja (SfM) orientirali fotografije, nakar smo z metodo večpogledni stereo (MVS) izdelali gosti oblak točk. Iz gostega oblaka točk smo naredili 3D model v obliki poligonske 3D mreže in ga opremili s teksturami. Iz orientiranih fotografij smo na podlagi 3D modelov naredili ortofote obeh spomenikov z vseh štiri strani. 3D modele smo med sabo tudi primerjali. Primerjava obeh spomenikov je pokazala, da sta skoraj enaka, razlike na posameznih ploskvah so med 0 – 25 mm. Razlike med karakterističnimi merami višin in širin posameznih sestavnih delov pa ne presegajo 1 cm. In the thesis, we carried out the survey of two terminal points of the Maribor trigonometric base using photogrammetric measurement. The points of the Maribor trigonometric base, established in 1860, consist of two parts: an upper pyramid part measuring about 1.90 m in height, and a lower square part measuring about 1.25 m in height. The northern base point numbered 218 is located on the edge of Orehova vas, while the southern point numbered 217 is situated on the edge of the village Starošince, with 6 km between them. Both monuments were photographed using a camera, and the Structure from Motion (SfM) technique was employed to orient the images. Subsequently, a dense point cloud was generated using the Multi-View Stereo (MVS) method. From the dense point cloud, a 3D model was created in the form of a polygonal 3D mesh and textured accordingly. Based on the oriented photographs, orthophotos of both monuments were generated from all four sides. The 3D models were also compared with each other. The comparison of the two monuments revealed their nearly identical nature, with differences on individual surfaces ranging between 0 to 25 mm. Differences in characteristic measurements of heights and widths of individual components do not exceed 1 cm. geodezija diplomska naloga VSŠ SfM/MVS fotogrametrija mariborska triangulacijska baza 3D model ortofoto južna bazna točka severna bazna točka geodesy graduation thesis SfM/MVS photogrammetry Maribor triangulation base 3D model orthofoto southern base point northern base point true false false [M.
