Rekonstrukcija zvoka na podlagi vibracij lamel glasbene skrinjice z uporabo hitre kamere

Kolovska, Evgenija (author), Slavič, Janko (mentor)

V zaključni nalogi je predstavljen postopek rekonstrukcije zvoka iz vibracij lamel glasbene skrinjice, posnetih s hitro kamero. Vibracije smo analizirali s pomočjo knjižnice pyIDI in usmerjenega algoritma Lucas-Kanade ter izračunane pomike pretvorili v zvočni signal. Rezultati bodo izpostavili prednosti in omejitve razvite metode ter nakazali njeno uporabnost na širšem področju optičnih pristopov zajem zvoka brez dotika, eksperimentalni mehaniki in diagnostiki strojev.

• Title: Sound reconstruction from vibrations of a music box comb using a high-speed camera

Abstract

This thesis presents a method for reconstructing sound from the vibrations of a music box comb recorded with a high-speed camera. The vibrations were analyzed using the pyIDI library and the directional Lucas-Kanade method algorithm, with the measured displacements converted into an audio signal. The results will point out benefits and limitations of the method and suggest usefulness within the wider scope of optical approaches to non-invasive sound recovery, experimental mechanics, and diagnostic practices in machines.
