Problem
Robotic subsea mapping, inspection and maintenance activities are impaired by water turbidity (e.g., marine snow). Current underwater imaging systems (e.g., 3D, optic) present serious limitations when operating in harsh underwater environments.
Nowadays, close range navigation missions are impaired, because the distance determination and object reconstruction are not accurate or reliable, even using available solutions using active imaging to project a pattern of light. Therefore, the limited visual perception capability of autonomous underwater vehicles (AUVs) restricts the use of such vehicles to medium/long range missions.
Solution
Underwater vision system for robotic applications in harsh underwater environments (e.g., marine snow).
Our solution is MARESye an innovative hybrid visual imaging system that provides dense and accurate 3D information in harsh and turbid (marine snow) underwater environments. MARESye consists of a compact hardware and an innovative software, that combines information from imaging techniques, multiple light stripe range (LSR) and a photometric stereo (PS).
This system was designed to extend the measurement range and to produce high density 3D estimations in dynamic underwater environments, with a novel synchronisation method, using a gate timing computer-implemented method.
Unique benefits
