20.500.12556/RUL-187325 Izdelava digitalnih dvojnikov zgodovinskih predmetov z uporabo brezkontaktne tehnike zajema Creation of digital replicas of historical objects using noncontact capture Namen diplomske naloge je bil raziskati pripravo delovnega okolja in postopka za zajem odsevnih kovinskih predmetov in površin za potrebe digitalnega arhiviranja. Diplomsko delo je nastalo v sodelovanju z Narodnim muzejem Slovenije. Raziskava je obravnavala digitalizacijo deloma in popolnoma odsevnih kompleksnih predmetov z uporabo laserskega zajema geometrije, projekcije strukturirane svetlobe in fotogrametrije. Poudarek je bil na zmanjševanju odsevnosti površin pri fotogrametričnem zajemu ter natančnem zajemu geometrije in barvnih podatkov. Raziskava je bila razdeljena na teoretični in eksperimentalni del. V teoretičnem delu so bile obravnavane metode, tehnologije in oprema, potrebe za digitalizacijo fizičnih predmetov v njihove digitalne dvojnike. V eksperimentalnem delu so bili izvedeni zajem, obdelava podatkov in izdelava digitalnih dvojnikov. Opredeljeni so bili izzivi, ki so se pojavili pri zajemu odsevnih predmetov, primerjani pa so bili tudi uporabljeni postopki in rešitve. Kot rezultat raziskave je bila razvita metodologija za zajem deloma in popolnoma odsevnih kompleksnih predmetov za potrebe arhiviranja in restavriranja. Primerjava uporabljenih pristopov je pokazala pomen skrbno pripravljenega delovnega okolja, postopka dodelave in ustreznih postopkov zajema za zmanjševanje neželenih odsevov za doseganje zanesljive reprodukcije geometrije ter natančnih barvnih informacij. The aim of the bachelor’s thesis was to investigate the preparation of the working environment and the procedure for capturing reflective metallic objects and surfaces for the purposes of digital archiving. The thesis was carried out in cooperation with the National Museum of Slovenia. The research addressed the digitization of partially and fully reflective complex objects using laser geometry capture, structured light projection, and photogrammetry. Particular emphasis was placed on reducing surface reflectivity in photogrammetric acquisition and on the accurate capture of geometry and color data. The research was divided into a theoretical and an experimental part. In the theoretical part, the methods, technologies, and equipment required for the digitization of physical objects into their digital twins were examined. In the experimental part, data acquisition, data processing, and the creation of digital twins were carried out. The challenges encountered during the capture of reflective objects were identified, and the applied procedures and solutions were also compared. As a result of the research, a methodology for capturing partially and fully reflective complex objects for archiving and restoration purposes was developed. The comparison of the applied approaches demonstrated the importance of a carefully prepared working environment, a finishing procedure, and appropriate acquisition procedures in reducing unwanted reflections and achieving reliable reproduction of geometry and accurate color information. odsevni predmeti polarizirana svetloba fotogrametrija laserski zajem 3D rekonstrukcija geometrije reflective objects polarized light photogrammetry laser scanning 3D geometry reconstruction true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-10 09:02:33 2026-09-10 09:02:36 2026-09-11 04:28:25 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 116326 30498.pdf 30498.pdf 1 489316AE38FFBBC6A7E706D2BC53FC84 1d9a57ae0fae9d84d3e62fb99a323b64ffae6b4ea771e07f6f0c9c2039037fb8 94d06ea5-ace5-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246890 Naravoslovnotehniška fakulteta 0 0 0
