Abstract

Real-time and full-color 3D inspection of underwater structures using the SeaVision system

Laser scanners are becoming increasingly interesting for industrial underwater applications. They offer higher resolution and accuracy compared to acoustic sensors, but also face limitations in challenging conditions. The optical properties of water are also a limitation on the transferability of technologies from the terrestrial domain. Laser stripers are the current state of the art for affordable underwater sensors, as time-of-flight systems do exist, but are expensive and bulky.

The Kraken SeaVision™ system combines a high-speed low-light color camera, with steerable red, green and blue lasers and a color LED light. This allows for a number of deployment options, and is especially suitable for vertical inspections of underwater structures. SeaVision has been tested in a combination of lab and real-life outdoor environments.

The content of this talk is to give an overview of the challenges, the technologies involved, and some examples of field data.
