About me

I received B.Sc. and M.Sc. degrees in Physics and Artificial Intelligence from the University of Patras and the University of Southampton, respectively. From 2020 to 2021, I was a Computer Vision engineer in SAGA Robotics, where I was involved in the FirstFleet, GRASPberry and other UKRI projects. My main research interests include vision guided fruit harvesting and vision based navigate-on in agricultural environments. By joining the CDT I will be able to contribute academically and produce high impact research in the agri-robotics sector.

MSc Project

Long-Term Visual Teach & Repeat in Agricultural Environments

Visual based navigation aims to provide affordable and accurate navigation in GPS-RTK denied environments. The Visual Teach & Repeat approach differentiates itself from other visual based approaches (SLAM) as it does not need to create metric maps to achieve navigation. In the general form of VT&R systems an operator drives the robot along a desired trajectory, and the robot during the repeat phase, attempts to follow the taught trajectory by associating information from on-board visual sensors against a stored map. In order to succeed in long-term navigation, a VT&R system needs to perform the repeat phase successfully at any time of the day despite high illumination variance or even gradual changes in the environment.
