DREGON: Dataset and Methods for UAV-Embedded Sound Source Localization

Abstract: This paper introduces DREGON, a novel publiclyavailable dataset that aims at pushing research in sound source localization using a microphone array embedded in an unmanned aerial vehicle (UAV). The dataset contains both clean and noisy in-flight audio recordings continuously annotated with the 3D position of the target sound source using an accurate motion capture system. In addition, various signals of interests are available such as the rotational speed of individual rotors and inertial measurements at all t… Show more

“…Drones have already been used by humanitarian organizations in places like Haiti and the Philippines to map areas after a natural disaster, using high-resolution embedded cameras, as documented in a recent United Nation report [1]. While research efforts have mostly focused on developing videobased solutions for this task [2], UAV-embedded audio-based localization has received relatively less attention [3], [4], [5], [6], [7]. Though, UAVs equipped with a microphone array could be of critical help to localize people in emergency situations, in particular when video sensors are limited by a lack of visual feedback due to bad lighting conditions (night, fog, etc.)…”

“…The problem of estimating the Direction of Arrival (DOA) of a propagating wave plays a fundamental role in many signal processing applications. More recently it has been of great interest for sound source localization, specially in search and rescue scenarios [1].…”

“…For the sound source localization problem, one of the main techniques employed is based on the time difference of arrival (TDOA), i.e., the delay that the propagating wave (sound) arrives at several microphones disposed in different locations [2]- [5]. However, in applications involving Unmanned Aerial Vehicle (UAV) the main problem arises from the ego noise and the fact that the sound source location and the microphones can be in movement [1].…”

“…Os estimadores do segundo tipo apresentam melhor desempenho com arranjos com sensores mais espaçados. Uma das principais vantagens do estimadores de DoAs baseados em TDoA com minimização LSé uma menor complexidade computacional quando comparados aos algoritmos baseados em busca em grade, típicos das técnicas SRP (do inglês, steered response power) [9], favorecendo aplicações em tempo real [10].…”
