Identifikacija nihanja na podlagi korelacije digitalnih slik

Šimic, Tilen (author), Slavič, Janko (mentor)

V zaključni nalogi so predstavljene metode identifikacije kinematike na podlagi korelacije digitalnih slik. V programskem okolju Python smo razvili aplikacijo za namene določanja nihanja in njegovih lastnosti s hitro kamero, na podlagi metode Lucas-Kanade. Opisana sta preizkusa aplikacije s sintetičnim posnetkom in posnetkom iz realnega primera, na katerem smo preverili vpliv nekaterih parametrov na izračun pomikov.

• Title: Vibration identification using digital image correlation

Abstract

In this final thesis methods of kinematics identification based on digital image correlation are presented. An application with the purpose of identifying vibrations and its characteristics using high-speed camera, based on Lucas-Kanade method was developed in the Python ecosystem. Experiments with syntetic and real recordings on which the effect of analysis parameters were tested are also presented.
