Abstract

Z razvojem terestričnih laserskih skenerjev (TLS) se je izdelava 3D-modelov kraških jam zelo poenostavila, saj laserski skenerji v krajšem času omogočajo več zajetih točk. S tem so se povečale tudi natančnost, hitrost in gostota zajetih točk. Z novejšima laserskima skenerjema Leica BLK360 in Riegl VZ-400 smo izmerili Planinsko in Skedneno jamo, kjer smo s pomočjo GNSS-inštrumenta in klasičnih meritev določili oslonilne in vezne točke. Na osnovi teh smo pozneje izvedli registracijo in georeferenciranje oblakov točk, zajetih z obema laserskima skenerjema. V okviru magistrske naloge smo na koncu izvedli analizo oziroma primerjavo omenjenih laserskih skenerjev, in sicer smo primerjali natančnost, doseg, hitrost, gostoto in zahtevnost na terenu. S primerjavo smo zbrali prednosti in slabosti obeh laserskih skenerjev in določili, kateri inštrument je najbolje uporabiti v kraškem svetu.

Secondary title: ǂThe ǂcomparison of BLK360 and Riegl VZ-400 for cave scanning
Secondary abstract: With the development of terrestrial laser scanners (TLS), the production of 3D models of karst caves has become very simplified, as laser scanners allow more captured points in a shorter time. This also increased the accuracy, speed and density of the captured points. With the newer laser scanners Leica BLK360 and Riegl VZ - 400, we measured Planinska cave and Skednena cave, where we determined the support and connection points, with the help of a GNSS instrument and classic measurements. Based on these, we later performed registration and georeferencing of point clouds, captured by both laser scanners. As part of the master's thesis, we carried out an analysis and comparison between the aforementioned laser scanners, where we compared accuracy, range, speed, density and complexity in the field. By comparison, we gathered the advantages and disadvantages of both laser scanners and determined which instrument is best suited for use in the karst world.
