Field deployable dynamic lighting system for turbid water imaging
(Massachusetts Institute of Technology, 2011)The ocean depths provide an ever changing and complex imaging environment. As scientists and researches strive to document and study more remote and optically challenging areas, specifically scatter-limited environments. ... -
An investigation into the characteristics and sources of light emission at deep-sea hydrothermal vents
(Massachusetts Institute of Technology, 2000)A spectral camera (ALISS - Ambient Light Imaging and Spectral System) was used to image ambient light from high-temperature vents at 9°N East Pacific Rise and the Juan de Fuca Ridge during 1997 and 1998 Alvin dive cruises. ... -
Large scale structure from motion for autonomous underwater vehicle surveys
(Massachusetts Institute of Technology, 2004)Our ability to image extended underwater scenes is severely limited by attenuation and backscatter. Generating a composite view from multiple overlapping images is usually the most practical and flexible way around this ... -
Large-area visually augmented navigation for autonomous underwater vehicles
(Massachusetts Institute of Technology, 2005)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 ...
