Structures oscillate with very small displacement amplitudes, particularly so at high frequencies, which are hard to measure with cameras. Camera measurements also produce large amounts of data, which should be analysed in a reasonable amount of time. A review of some of the Optical Flow methods used to identify displacements from videos and some modal parameter identification techniques is presented. The influential parameters and the potential of high-speed camera measurements are discussed. The greatest contributions of this work are the determination of the displacement resolution potential, the hybrid modal identification below the camera's noise floor and the developed measurement technique for identification of individual displacement spectral components from images produced by still-frame cameras"},{"@xml:lang":"sl","#text":"To delo obravnava uporabo kamer za meritev polnega polja dinamskih odzivov struktur. Strukture, predvsem pri višjih frekvencah, nihajo z zelo majhnimi amplitudami pomikov in so ti težko zaznavni s kamerami, poleg tega meritve s kamerami predstavljajo velike količine podatkov, katere je potrebno analizirati v smiselnem času. V delu je predstavljen pregled nekaterih metod identifikacije pomikov iz slik in metod identifikacije modalnih parametrov. Raziskani so vplivni parametri in potenciali meritev s hitrimi kamerami. Najpomembnejši izsledki raziskav so določitev potenciala ločljivosti premikov, hibridna modalna identifikacija odziva pod nivojem šuma in razvit merilni postopek za meritve spektralnih komponent nihanja s klasičnimi kamerami"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"visokošolska dela"},{"@xml:lang":"en","#text":"theses and dissertations"},{"@rdf:resource":"http://www.wikidata.org/entity/Q1266946"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-6G5ZW4G4","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-6G5ZW4G4"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-6G5ZW4G4/ac28200a0877abb66b370f4-218-2f-47f-a/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-6G5ZW4G4/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-6G5ZW4G4"}}}}
