Analysis of Efficient Transmission Methods of Grid Maps for Intelligent Vehicles

Robin Dehler, Dominik Authaler, Aryan Thakur +2

Grid mapping is a fundamental approach to modeling the environment of intelligent vehicles or robots. Compared with object-based environment modeling, grid maps offer the distinct…

The ADUULM-360 Dataset -- A Multi-Modal Dataset for Depth Estimation in Adverse Weather

Markus Schön, Jona Ruof, Thomas Wodtko +2

Depth estimation is an essential task toward full scene understanding since it allows the projection of rich semantic information captured by cameras into 3D space. While the field…

Self-Assessment of Evidential Grid Map Fusion for Robust Motion Planning

Oliver Schumann, Thomas Wodtko, Michael Buchholz +1

Conflicting sensor measurements pose a huge problem for the environment representation of an autonomous robot. Therefore, in this paper, we address the self-assessment of an eviden…

Globally Optimal Multi-Scale Monocular Hand-Eye Calibration Using Dual Quaternions

Thomas Wodtko, Markus Horn, Michael Buchholz +1

In this work, we present an approach for monocular hand-eye calibration from per-sensor ego-motion based on dual quaternions. Due to non-metrically scaled translations of monocular…
