Določitev spremembe geometrije deformabilne cevi iz oblaka točk terestričnega laserskega skeniranja : magistrsko delo = Determining the change in the geometry of a flexible pipe using terrestrial laser scanning point cloud data : master thesisSojer, UrošV magistrskem delu smo preverjali spremembo geometrije deformabilne cevi iz oblaka točk terestričnega laserskega skeniranja. Sprva smo s terestričnim laserskim skenerjem opravili meritve v cevi ter ... nasutja zemljine nad cevjo. Opravljene meritve so predstavljale osnovo za izdelavo registriranega oblaka točk. Z namenom preverjanja spremembe geometrije cevi iz oblaka točk smo izdelali programsko opremo. Dimenzijo cevi smo določali na način, da smo oblaku točk cevi izravnali elipso po metodi najmanjših kvadratov. Izravnana elipsa je predstavljala parametre premera cevi v vertikalni in horizontalni smeri. Rezultate premera cevi smo nato analizirali na primeru cevi, ki ni vgrajena in prosto leži na terenu, ter na dveh primerih vgrajene cevi. Prvi primer vgrajene cevi je cev, ki je zasuta s predpisanim materialom, drugi primer pa je cev, ki je v celoti betonirana ter nato zasuta s predpisanim materialom. Iz oblaka točk, ki predstavlja nasutje zemljine nad cevjo, smo dobili podatke o višini nasutja. Le-ti so nam omogočali analizo vpliva višine nasutja na spremembo geometrije cevi. Poleg meritev s terestričnim laserskim skenerjem smo meritve premera v horizontalni in vertikalni smeri na začetku, sredini in koncu vsakega sklopa cevi opravili z ročnim laserskim razdaljemerom. Različna metoda izmere nam je služila za ugotavljanje razlik med obema metodama izmere premera cevi. Magistrsko delo predstavlja poglobljen pregled in ovrednotenje uporabe terestričnega laserskega skenerja za potrebe določanja spremembe geometrije cevi.Type of material - master's thesis ; adult, seriousPublication and manufacture - [Ljubljana : U.
