Abstract

V okviru magistrske naloge smo vzpostavili geodetsko mrežo, sestavljeno iz osmih točk. Meritve smo izvedli s klasično terestrično metodo izmere v kombinaciji s statično metodo izmere GNSS. Ločeno smo izvedli položajno in višinsko izravnavo meritev po metodi najmanjših kvadratov. Rezultate izravnave smo podali v državnem prostorskem koordinatnem sistemu. Vzpostavljeno geodetsko osnovo smo uporabili za izmero in izračun oslonilnih točk. Oslonilne točke smo uporabili za georeferenciranje oblaka točk terestričnega laserskega skeniranja. Oblak točk, ki smo ga registrirali, georeferencirali, očistili (filtrirali) in izvozili, je omogočal vizualno predstavitev cerkve sv. Janeza Krstnika in kamnitega mostu čez Jezernico v Bohinju. Med izmero je potekala določitev koordinat zvonika cerkve sv. Janeza Krstnika, saj je zvonik viden iz širše okolice in uporaben za orientacijo kasnejših izmer. Koordinate cerkvenega zvonika smo določili s kombinacijo klasične terestrične metode izmere in statične metode izmere GNSS ter s postopkom terestričnega laserskega skeniranja. Rezultate izračuna obeh metod smo ovrednotili in med seboj primerjali. Dodatno smo ocenili kakovost vsedržavnega modela trikotniške transformacije.

Secondary title: Processing a point cloud of St. John the baptist's church in Bohinj
Secondary abstract: As part of the master's thesis, we established a geodetic network consisting of eight points. The measurements were performed with the classical terrestrial measurement method in combination with the static GNSS measurement method. Horizontal and height adjustment was performed separately by the method of least squares. The results of the adjustment were given in the national spatial coordinate system. The established geodetic basis was used to measure and calculate the control points. The control points were used to georeference the terrestrial laser scanning point cloud. The point cloud, which we registered, georeferenced, filtered and exported, enabled a visual presentation of the church of St. John the Baptist and the nearby stone bridge over the Jezernica river in Bohinj. During the measurement, the coordinates of the belfry of the church of St. John the Baptist were determined, as the bell tower is visible from the wider surroundings and thus useful for orientation in the future measurements. The coordinates of the church belfry were determined with the classical terrestrial measurement method and the static GNSS measurement method, as well as with the terrestrial laser scanning. The results of the calculation were evaluated and compared with each other. We further assessed the quality of the Slovenian triangle-based transformation model.
