Abstract
An observation unit (30) for underwater deployment on/in a submerged earth layer (12) or structure. The unit comprises a housing (32), a light source (36), an underwater imaging device (40), a processor device (44), and a communication device (35). The housing supports the underwater observation unit relative to the submerged layer or structure. The light source is fixed to the housing, and configured to emit light into the unit's surroundings. The imaging device is attached to the housing, and configured to acquire image data of a second light source located within a FOV of the camera that covers the surroundings of the unit. The processor device is configured to determine positional data of the second light source relative to the imaging device, from the image data. The communication device is configured to transmit the positional data to another underwater observation unit, an underwater vehicle, or an underwater processing station.
