Analysis and comparison of digitalization procedures for the purpose of reverse engineering

Magistrsko delo obravnava proces vzvratnega inženirstva na podlagi podatkov, pridobljenih z različnimi načini digitalizacije. Opisan je celoten postopek pridobivanja podatkov v obliki oblaka točk, na podlagi katerih je možno, v procesu vzvratnega inženirstva, rekonstruirati površine. Na praktičnih primerih uporabe treh različnih sistemov digitalizacije, je predstavljeno delo z vsakim posebej. Prav tako je za vsak digitalizacijski sistem, po korakih opisan način digitalizacije, in nekatera priporočila. V sklepnem dejanju, kjer smo izvedli primerjavo vseh treh, v praktičnem delu uporabljenih, sistemov digitalizacije in priporočila, kdaj je smiselno uporabiti določen sistem. Ugotovljeno je bilo, da ni možno enoznačno določiti optimalnega sistema digitalizacije, ampak je možno le izbrati najugodnejšega, za določeno vrsto aplikacije. Glede na to, da se na trgu pojavlja vse več različnih digitalizatorjev, je možno na podlagi ugotovitev, zbranih skozi nalogo pridobiti osnovno predstavo o možnostih, ki jih ponuja določen sistem.This master’s thesis deals with the process of reverse engineering on the basis of data, gathered with different methods of digitalization. It describes the entire process of data acquisition in the form of point-cloud, on the basis of which it is possible to reconstruct surfaces in the process of reverse engineering. With the use of three different systems of digitalization, I demonstrate how to work with each of them, using practical examples. I also include a step-by-step description for each separate digitalization process with additional recommendations. In the conclusion, where a comparison between all three systems was made, those used in practical examples and the recommendations when it is sensible to use a certain one, we found out, that it is not possible to unambiguously determine the optimal one, it is however possible to choose the one, that is the best fit for a specific application. Taking into account, that more and more digitizers are available on the market, it is possible, on the basis of my findings, to get a basic notion what a certain system has to offer
