Mattia D'Urso

PhD candidate · 3D Computer Vision

I am a PhD student in Prof. Friedrich Fraundorfer's group at the Institute for Visual Computing (IVC) at Graz University of Technology, Austria.

I am currently visiting the Computer Vision and Geometry Group at ETH Zürich, supervised by Prof. Marc Pollefeys and Dr. Daniel Barath.

Previously, I gained professional experience at the Canva office in Vienna and at Infineon Technologies in Villach, Austria.

I hold a joint Master's double degree in Computer Science from the University of Klagenfurt and the University of Udine, where I also completed my Bachelor's degree in the same field.

TerraSky3D is a high-resolution 4K dataset of European landmarks comprising approximately 50,000 images across 150 scenes, specifically designed to bridge the modality gap between ground-level and aerial perspectives for 3D reconstruction. It provides curated camera poses and dense depth maps. Data is available here.
