Robust Underwater Visual SLAM Fusing Acoustic Sensing

Elizabeth Vargas, Raluca Scona, Jonatan Scharff Willners, Tomasz Luczynski, Yu Cao, Sen Wang +1

ICRA 2021poster

In this paper, we propose an approach for robust visual Simultaneous Localisation and Mapping (SLAM) in underwater environments leveraging acoustic, inertial and altimeter/depth sensors. Underwater visual SLAM is challenging due to factors including poor visibility caused by suspended particles in w…

Impact of Microphone Array Configurations on Robust Indirect 3d Acoustic Source Localization

Elizabeth Vargas, Keith E. Brown, Kartic Subr

ICASSP 2018accepted

Acoustic source localization (ASL) is an important problem. Despite much attention over the past few decades, rapid and robust ASL still remains elusive. A popular approach is to use a circular array of microphones to record the acoustic signal followed by some form of optimization to deduce the mos…
