Resilience, collapse and reorganization of a rangeland socio-ecological system in South Africa
(2016-05-24)
Communal rangelands in semi-arid areas are complex socio-ecological systems (SES). Their complexity arises from non-linear feedbacks between the social- and the ecosystem. To understand the social system requires tackling ...
Robot Navigation Beyond Planning the Shortest Path
(2021-04-16)
Over the last decade, the demand for autonomous mobile robots has been growing continuously. Applications range from mobile manipulators operating on factory floors to autonomous cars driving in urban environments. A common ...
Graph-based Sliding Window Localization and Map Refinement for Automated Vehicles
(2021-10-12)
Localization is an essential task in automated driving and advanced driver assistance systems. The precise location of a vehicle is required for extracting information from a map about the vehicle's environment. The map ...
Robot Mapping and Navigation in Real-World Environments
(2018-11-27)
Robots can perform various tasks, such as mapping hazardous sites, taking part in search-and-rescue scenarios, or delivering goods and people. Robots operating in the real world face many challenges on the way to the ...
Extrinsic Calibration and Ego-Motion Estimation for Mobile Multi-Sensor Systems
(2018-12-20)
Autonomous robots and vehicles are often equipped with multiple sensors to perform vital tasks such as localization or mapping. The joint system of various sensors with different sensing modalities can often provide better ...
Visual Place Recognition in Changing Environments
(2019-10-10)
Localization is an essential capability of mobile robots and place recognition is an important component of localization. Only having precise localization, robots can reliably plan, navigate and understand the environment ...
Spatio-Temporal Registration Techniques for Agricultural Robots
(2021-06-16)
A critical challenge that we face today is to meet the rising demand for food, feed, fiber, and fuel from an ever-growing world population. We must meet this demand within the limited arable land available to us and do so ...
Visual Odometry and Sparse Scene Reconstruction for UAVs with a Multi-Fisheye Camera System
(2019-06-13)
Autonomously operating UAVs demand a fast localization for navigation, to actively explore unknown areas and to create maps. For pose estimation, many UAV systems make use of a combination of GPS receivers and inertial ...
A water storage reanalysis over the European continent: assimilation of GRACE data into a high-resolution hydrological model and validation
(2019-04-18)
Continental water storage and redistribution within the Earth’s system are key variables of the terrestrial water cycle. Changes in water storage and fluxes may affect resources for drinking water and irrigation, lead to ...
