20.500.12556/RUL-112949 Geodetski monitoring v kraški jami Ulica pečina magistrsko delo Geodetic monitoring of the ground in karst cave Ulica pečina master thesis Slovenija je znana po svojih naravnih znamenitostih, med katerimi je tudi kraški svet in številne kraške jame. Kraška jama Ulica pečina je zaradi dveh vhodov in posledično prevetrenosti posebna, saj zaradi tega prihaja do večjih nihanj temperatur med letnimi časi. V magistrski nalogi smo z uporabo terestričnega laserskega skeniranja določali premike tal v kraški jami Ulica pečina. Premike tal v kraški jami, ki nastajajo zaradi meteoroloških vplivov, smo ugotavljali na podlagi dveh izmer v različnem časovnem obdobju. V praktičnem delu magistrske naloge smo v jami z uporabo klasične tahimetrične izmere vzpostavili lokalno geodetsko mrežo, ter z uporabo terestričnega laserskega skenerja skenirali jamo. Lokalno geodetsko mrežo smo izravnali, analizirali premike točk in ugotavljali stabilnost točk mreže. Podatke skeniranja smo obdelali s programom RiSCAN PRO in jih nato medsebojno analizirali s programom CloudCompare. Rezultate analize oblakov točk skeniranj v dveh različnih časovnih obdobjih, smo ovrednotili in prikazali najbolj aktivna območja tal jame v obravnavanem časovnem obdobju. Slovenia is known for its natural sights, which includes the Karst terrain and numerous karst caves. Karst cave named Ulica pečina is unique due to its two entrances and, consequently, the overburden, as this causes major fluctuations in temperatures during the seasons. In the Master's thesis, terrestrial laser scanning has been applied to determine the movement of the soil in the Karst cave Ulica pečina. These soil movements in the karst cave, which arise due to meteorological influences, were determined on the basis of two measurements in different periods of time. In the practical part of the Master's thesis, a local geodetic network was set up in the cave using a classical tachymetric measurements and the cave has been scanned using a terrestrial laser scanner. The local geodetic network has been adjusted and the movements of the points analyzed to determine the stability of the network points. The scanning data was processed with RiSCAN PRO. Afterwards it was mutually analyzed and compared with CloudCompare. The results of the analysis of point clouds of scans in two different time periods were evaluated and the interesting areas of soil pits were displayed. terestrično lasersko skeniranje lokalna geodetska mreža obdelava opazovanj kraška jama ulica pečina določitev premikov tal terrestial laser scanning local geodetic network observation processing karst cave Ulica pečina determination of ground movements true true false A.
