NON-CONTACT METHOD OF MEASUREMENT USING 3D SCANNER

U samom uvodu ovog završnog rada objašnjeno je na koji način su nastali uređaji za trodimenzionalnu kontrolu. Razvoj industrije i proizvodnja složenih predmeta uvjetovali su razvoj trokoordinatnih mjernih uređaja (CMM) koji većinom rade na taktilni princip dok su se prema istom principu razvili i skeneri koji se pretežito koriste prilikom kontrole kompleksnih površina. U ovom radu detaljnije je predstavljen 3D skener tvrtke Creaform, HandySCAN 700, kojeg smo koristili za skeniranje te kasnije, koristeći prateći softwere VXelements, obradili podatke i izradili mjerni izvještaj. Princip korištenja VXelements softwera temelji se na podešavanju ispravnih parametara prije početka samog skeniranja objekta. Nakon skeniranja i brze kontrole skenirana datoteka detaljno se obrađuje te samim time dolazimo do željenog rezultata. Krajnji cilj bio nam je dobiti rezultate na osnovi usporedbe sa CAD modelom i poravnanjem na 2 različita načina. Nakon učinjenog poravnanja i usporedbe došli smo do zaključka da je za predmete od brizgane plastike BEST FIT najoptimalnije rješenje te nam ono daje realne rezultate mjerenja.In the introduction of this paper, it is explained how the devices for three-dimensional control have been invented. The development of the industry and the production of complex objects have caused the development of three-coordinate measuring machines (CMM) that mostly operate on a tactile principle, while according to the same principle, scanners that are used for controlling complex surfaces have been developed. In this paper the Creaform 3D scanner, model HandySCAN 700, has been presented. Later using the accompanying software VXelements data has been processed and a measurement report has been created. The principle of using the VXelements software is based on adjusting the correct parameters before the start of the scan. After scanning and quick control the scanned file is processed in detail. This way to desired result is achieved. The final goal was to get results based on a comparison with the CAD model and alignment in 2 different ways. After the alignment and comparison, we have come to the conclusion that the BEST FIT alignment is the most optimal solution for plastic-injection items and gives us realistic measurement results
