Abstract

Akustična kamera je naprava za lokalizacijo zvočnih virov. Sestavljena je iz polja senzorjev zvočnega tlaka in video kamere. S tem sega v področje akustike in slikovne obdelave. Z uporabo različnih algoritmov iz zajetega zvoka lahko izračunamo koordinate izvora. Večina algoritmov temelji na uporabi križne korelacije in principu razlike v času prihoda TDOA. Namen dela je bilo načrtovanje in implementacija lastnega prototipa. Iz tega razloga smo preučili delovanje in aplikacije akustičnih kamer. Poudarek je bil na mikrofonskih poljih , ki so njihov glavni del. Izdelan prototip bi se dalo izboljšati z uporabo več mikrofonov in nadgradnjo uporabljenih algoritmov.

Secondary title: Acoustic camera
Secondary abstract: Acoustic camera is a device for sound source localization. It consists of a sound pressure sensor array and a video camera. With this it combines fields of acoustics and image processing. With use of different algorithms we can calculate the coordinates of the sound source. Most of the algorithms are based on usage of cross correlation and principle of time difference of arrival TDOA. The purpose of this project was design and implementation of our own prototype. For this reason we have studied the operation and applications of acoustic cameras. The emphasis was on microphone arrays, which are their main part. Finished prototype can be improved with the use of more microphones and an upgrade of used algorithms.
