Real-Time Dense 3D Mapping of Underwater Environments

ICRA 2023poster

This paper addresses real-time dense 3D reconstruction for a resource-constrained Autonomous Underwater Vehicle (AUV). Underwater vision-guided operations are among the most challenging as they combine 3D motion in the presence of external forces, limited visibility, and absence of global positionin…

SM/VIO: Robust Underwater State Estimation Switching Between Model-based and Visual Inertial Odometry

ICRA 2023poster

This paper addresses the robustness problem of visual-inertial state estimation for underwater operations. Underwater robots operating in a challenging environment are required to know their pose at all times. All vision-based localization schemes are prone to failure due to poor visibility conditio…
