20.500.12556/RUL-159550 Mobilni telefon kot 3D optični čitalnik: zmogljivost in uporaba Mobile phone as a 3D optical scanner: performance and use 3Dčitalniki so draga oprema. Če hočemo kvalitetne rezultate, moramo odšteti veliko vsoto denarja. So pa na trgu mobilne aplikacije, ki omogočajo 3Dskeniranje zgolj s povprečnim mobilnim telefonom. V tem delu je podrobno vrednotena in prikazana uporaba mobilnega telefona kot 3Dčitalnika. Primerjane so tri najpogostejše metode (aplikacije) skeniranja z mobilnim telefonom, ki smo jih uporabili za skeniranje treh bistveno različnih predmetov. Tako smo dobili dobro sliko uporabnosti posamezne metode. Rezultati skeniranja nato služijo za prikaz procesa obratnega inženirstva, se pravi za prikaz modeliranja oblaka točk in prikaz simuliranja mehanskih obremenitev dobljenega modela. V teoretičnem delu zaključne naloge je zajeta teorija, nanašajoča se na obravnavano tematiko skeniranja, modeliranja oblakov točk in simuliranja. Po pričakovanjih se je izkazalo, da je vsaka metoda 3Dskeniranja uporabna za svoj nabor namenov. Z dobljenimi 3Dmrežami smo z minimalnimi težavami prišli do parametričnih modelov predmetov in na enem izvedli simulacijo obremenitev. 3D scanners are expensive. If we want highquality results, we must invest a considerable sum. However, there are mobile applications on the market that allow 3D scanning with just an average mobile phone. This paper extensively evaluates and demonstrates the use of a mobile phone as a 3D scanner. The three most common methods (applications) for scanning with a mobile phone, which were used to scan three substantially different objects, are compared. This provided a good overview of the usability of each method. The scanning results are then used to demonstrate the reverse engineering process, specifically for modeling point clouds and simulating mechanical loads on the obtained model. The theoretical part of the final thesis includes theory related to the discussed topics of scanning, point cloud modeling, and simulation. As expected, it turned out that each 3D scanning method is useful for its set of purposes. With the obtained 3D meshes, we were able to create a parametric model of the object with minimal complications and perform load simulations on it. 3D-skeniranje obratno inženirstvo optični čitalnik modeliranje simuliranje oblak točk 3D scanning reverse engineering optical scanner modeling load simulation point cloud true false false [N.
