Vpliv barvne globine sinusnega vzorca na natančnost merjenja tridimenzionalnih površin z metodo faznega zamika [Elektronski vir]Kladnik, Andraž ; Pavlovčič, Urban ; Jezeršek, MatijaPotreba po hitrem merjenju kompleksnih tridimenzionalnih površin je vedno večja, saj omogoča nadzor kvalitete izdelkov, hitrejše vzvratno inženirstvo in rekonstrukcijo delov človeškega telesa. Ker so ... merilne razdalje kratke, zahteve po natančnosti pa visoke, je uporaba triangulacijskih metod v kombinacij s strukturiranim osvetljevanjem zelo pogosta. Ena zanimivejših metod je metoda faznega zamika v kombinaciji z Grayevo kodo, ki omogoča kratke čase merjenja in visoko natančnost tudi pri nezveznih površinah. Za izračun faznega zamika moramo na merjeni objekt projicirati tri sinusne vzorce, katerih barvna globina je najpogosteje 8 bitna. Namen eksperimenta je bil okarakterizirati vpliv barvne globine na natančnost meritve. Projiciranje manjših barvnih globin je ugodno, saj je zahtevan čas osvetlitve projektorja pri njih krajši, kar posledično skrajša čas merjenja. Na podlagi opravljenih preizkusov smo ugotovili, da razlik med natančnostjo meritve ob projiciranju 8, 7 ali 6 bitnega vzorca ni, medtem ko je ob projiciranju vzorcev manjših globin prišlo do nepravilnosti na izmerjeni površini. Uporaba 6 bitnega vzorca na primeru uporabljenega merilnega sistema omogoči več kot trikrat krajši čas merjenega osvetljevanja objekta.Source: [Zbornik del] [Elektronski vir] (F. 23-29)Type of material - conference contributionPublish date - 2017Language - slovenianCOBISS.SI-ID - 15654171
