Abstract

Tema ovog rada je usporedba mogućnosti skenera Creality CR-Scan 01 i Tupel 3D Dental Scanner pri skeniranju osnovnih geometrijskih oblika, te usporedba pripadajućih programskih aplikacija. 3D skeniranje je proces stvaranja digitalnog zapisa nekog fizičkog objekta, okoline ili čovjeka, čija primjena je sve učestalija u različitim područjima, te nastavlja rasti s razvojem novih tehnologija 3D skeniranja. Ovaj rad ponajviše opisuje tehnologiju strukturiranog svijetla koja se koristi u radu navedenih 3D skenera. Također, opisani su i parametri koji utječu na proces skeniranja, pojašnjeni su koraci procesa skeniranja te koraci naknadne obrade dobivenih skenova, za svaku programsku aplikaciju zasebno, kako bi sama usporedba njihovih mogućnosti kasnije bila jasnija. Provedeno je probno skeniranje kako bi se definirao smislen testni postav geometrijskih oblika za usporedbu, koji se sastojao od kocke kao osnove i promjenjivih nastavaka: polukugla, stožac, valjak, kocka i piramida. Korišteno je osam kombinacija izmjenom nastavaka na kocki s jednim utorom te kocki s dva utora za nastavke. Dobiveni i obrađeni 3D modeli uspoređivali su se s referentnim modelom u izabranim karakterističnim točkama.

Abstract (english)

The topic of this thesis is a comparison of the capabilities of the Creality CR-Scan 01 scanner and the Tupel 3D Dental Scanner when scanning basic geometric shapes, and a comparison of the associated software applications. 3D scanning is a process of creating a digital record of a physical object, environment or person, with increasingly common application in different areas and continuous growth along with the development of new 3D scanning technologies. This thesis mainly describes structured light technology that is used in the work of the mentioned 3D scanners. Also, the parameters that affect the scanning process are described, the steps of the scanning process and the steps of post-processing of the resulting scans, for each software application separately, so that the comparison of their capabilities would be clearer later. A test scanning was performed to define a useful test set of geometric shapes for comparison, which consists of a cube as a base and variable extensions: hemisphere, cone, cylinder, cube and pyramid. Eight combinations were used by changing the extensions on a cube with one slot and a cube with two extension slots. The obtained and processed 3D models were compared to the reference model at selected characteristic points.
