Abstract
This report discusses preliminary experimental investigations into the use of optical imaging to track a UUV (Unmanned Underwater Vehicle) that would be docking with a submarine. Two different types of underwater cameras were used to image a variety of optical “targets”, under controlled but realistic conditions, at Defence R&D Canada – Atlantic’s Acoustic Calibration Barge (ACB) in Bedford Basin near Halifax, Nova Scotia. A variety of imaging methods are employed and evaluated. The investigation provides a baseline assessment of the potential for imaging a UUV, both passively and with an active light source on the UUV. The results show that UUVs can be imaged at ranges of at least 16 metres under certain environmental conditions, but that the effective range will be highly dependent on water turbidity and ambient light.
