SeaVision™

The Kraken SeaVision™ system is a revolutionary new take on subsea 3D laser imaging. Designed to operate in a twin scanning configuration, with adjustable baseline, SeaVision can generate very high resolution 3D scans in full color. This is due to one of the unique features of SeaVision™ which uses a Tri-Color laser system to produce full color imagery. Each unit has a low-light underwater camera, a high power LED light, and steerable RGB-line lasers.

Innovative on-board processing techniques developed for Kraken’s Synthetic Aperture Sonar use internal motion compensation to produce a full 3D scan of 1.2 million points in 4 seconds, even on moving platforms. An external INS is not required and integral motion data can be exported to the vehicles control software. An auto-calibration systems allows for flexible mounting options to fit a variety of platforms including small ROV’s, Hovering Vehicles, and AUV’s. Eye Safe lasers allow for in field calibration which can be accomplished quickly in air, on deck, making it ideal for fly away, or temporary applications.
