An Integrated System for Geophysical Navigation of Autonomous Underwater Vehicles.

Geophysical Navigation of Autonomous Underwater Vehicles Using Geomagnetic Information ?

This paper addresses the general problem of Autonomous Underwater Vehicle navigation by exploiting the availability of terrain and geophysics-related data. Geophysical navigation algorithms are derived to estimate the position and velocity of an AUV in the presence of unknown ocean currents and sensor biases. The current implementation merges acoustic and magnetic measurements with dead-reckoni...

Mosaic Based Navigation for Autonomous Underwater Vehicles

We propose an approach for vision-based navigation of underwater robots that relies on the use video mosaics of the sea bottom as environmental representations for navigation. We present a methodology for building high quality video mosaics of the sea bottom, in a fully automatic manner, that ensures global spatial coherency. During navigation, a set of efficient visual routines are used for th...

Precision Navigation and Control for Autonomous Underwater Vehicles

Large-Area Visually Augmented Navigation for Autonomous Underwater Vehicles

This thesis describes a vision-based, large-area, simultaneous localization and mapping (SLAM) algorithm that respects the low-overlap imagery constraints typical of autonomous underwater vehicles (AUVs) while exploiting the inertial sensor information that is routinely available on such platforms. We adopt a systems-level approach exploiting the complementary aspects of inertial sensing and vi...
