Vision-Depth Landmarks and Inertial Fusion for Navigation in Degraded Visual Environments

no code implementations5 Mar 2019 Shehryar Khattak, Christos Papachristos, Kostas Alexis

This paper proposes a method for tight fusion of visual, depth and inertial data in order to extend robotic capabilities for navigation in GPS-denied, poorly illuminated, and texture-less environments.

Keyframe-based Direct Thermal-Inertial Odometry

no code implementations3 Mar 2019 Shehryar Khattak, Christos Papachristos, Kostas Alexis

This paper proposes an approach for fusing direct radiometric data from a thermal camera with inertial measurements to extend the robotic capabilities of aerial robots for navigation in GPS-denied and visually degraded environments in the conditions of darkness and in the presence of airborne obscurants such as dust, fog and smoke.

Marker based Thermal-Inertial Localization for Aerial Robots in Obscurant Filled Environments

no code implementations2 Mar 2019 Shehryar Khattak, Christos Papachristos, Kostas Alexis

For robotic inspection tasks in known environments fiducial markers provide a reliable and low-cost solution for robot localization.
