My research interests are visual and visual-inertial SLAM, robotics, and 3D reconstruction. I like to apply both traditional methods and deep learning.

An open-source visual-inertial odometry system with state-of-the art results. See https://github.com/lukasvst/dm-vio

As a follow-up of our previous work GN-Net, LM-Reloc boosts the performance of direct image alignment for relocalization using a novel loss formulation, and a pose estimation network.

Using our novel Gauss-Newton loss we improve the robustness of direct methods against strong illumination changes and bad initializations. This allows us to accurately relocalize between different weathers. Project Page

In my Master thesis on direct visual-inertial odometry we demonstrate state-of-the-art performance on the EuRoC dataset. Project Page

In my Bachelor thesis I have used LSD-SLAM to explore an unknown environment with an autonomous drone.
