Mapping the seabed with cutting-edge applications and research in photogrammetric computer vision, image analysis and remote sensing

About the Research Group

3[Deep]Vision is an Award Winning research group performing cutting-edge research and developing applications in the intersection of machine learning, computer vision and 3D mapping of the shallow seabed.

The determination of accurate bathymetric information is a key element for near offshore activities, hydrological studies such as coastal engineering applications, sedimentary processes, hydrographic surveying as well as archaeological mapping and biological research. UAV imagery processed with Structure from Motion (SfM) and Multi View Stereo (MVS) techniques can provide a low-cost alternative to established shallow seabed mapping techniques offering the important visual information as well. 3[Deep]Vision group, in order to overcome the water refraction errors, employ machine learning tools that are able to learn the systematic underestimation of the estimated depths and deliver bathymetric information in a centimeter accuracy level.

Research Applications: Shallow water mapping for Constructions, Underwater Archaeology, Biological Monitoring, Benthic Cover Mapping, Marine Litter Detection

We use UAV-borne or airborne imagery to generate seamless orthoimages and maps of the land and the seabed with very accurate depth contours.

Accurate and very detailed bathymetric information in the form of 3D point clouds, 3D meshes or colourscaled images

Semantic classification of the seabed.

We have big experience in seabed mapping applications using UAV imagery and Machine Learning, having developed robust and extremely reliable models to compensate for refraction effects.

Awarded by the European GNSS Agency (GSA) - Europa EU

We have been awared with the 1st Prize in the GeomaticsOnTheMove contest 2020!
