Use of alternative scanning devices for creation of 3D models of machine parts

Snimanje 3D informacija bilo koje površine i danas je još uvijek veliki izazov. Neke komercijalne tehnike i tehnologije snimanja u uporabi su nekoliko godina, ali je potreban hardver i softver koji je još uvijek preskup za korisnike. Ovaj članak daje nekoliko jeftinijijih alternativnih postupaka snimanja površine, na temelju "open source" elemenata za komercijalnu uporabu beskontaktnih 3D skenera i dokazuje da su dobiveni podaci pogodni ne samo za hobi prostornu digitalizaciju, nego i za uporabu u industriji. U dijelu rada ukratko je opisan proces digitalizacije s nekoliko freeware i shareware programa.Capturing of 3D information about any kind of surface is currently a big challenge. A few proven commercial techniques and technologies are in use for a couple of years, but needed hardware and software are still too expensive for ordinary users of PC. This article provides a few cheaper alternatives based on open source elements to commercial non-contact 3D scanners and proves that the obtained data are suitable not only for hobby home spatial digitization but also for requisites in the industry. In various parts of the contribution there is a brief description of digitization process with mentioned freeware and shareware applications
