Visual navigation of a virtual blowfly
… their flight path mainly on the basis of visual motion information. Modelling the motion pathway in the fly visual system and closing the control loop to behaviour is the topic of this thesis. Like many other animals, the blowfly exploits the optic flow, a characteristic pattern of image …

Efficient visual navigation of hierarchically structured graphs
Visual navigation of hierarchically structured graphs is a technique for interactively exploring large graphs that possess an additional hierarchical structure. This structure is expressed in form of a recursive clustering of the nodes: in call graphs of telephone networks, for instance, the nodes …

Human Visual Navigation: Effects of Visual Context, Navigation Mode, and Gender
Abstract This thesis extends research on human visual path integration using optic flow cues. In three experiments, a large-scale path-completion task was contextualised within highly-textured authentic virtual environments. Real-world navigational experience was further simulated, through the …

Robust Flight Navigation with Liquid Neural Networks
Autonomous robots can learn to perform visual navigation tasks from offline human demonstrations, and generalize well to online and unseen scenarios within the same environment they have been trained on. It is fundamentally challenging for these intelligent agents to take a step further and …

Large-area visually augmented navigation for autonomous underwater vehicles
… complementary aspects of inertial sensing and visual perception from a calibrated pose-instrumented platform. This systems-level strategy yields a robust solution to underwater imaging that overcomes many of the unique challenges of a marine environment (e.g., unstructured terrain, low-overlap …

Significance of omnidirectional fisheye cameras for feature-based visual SLAM
Robust GPS-denied navigation of mobile robots is becoming increasingly important as robots become more ubiquitous. Cameras are powerful sensors for this application due to their low cost and high information density. The task of using camera-based computer vision techniques for navigation is …

ENABLING THE TEST AND EVALUATION OF AUTONOMOUS FUNCTIONS THROUGH STANDARDIZATION OF UAS INTEGRATION
… demonstrated in flight through basic visual navigation tasks in which the aircraft detected and navigated toward a target using onboard perception and autonomy software. The results confirm that the proposed framework provides a robust and portable method for integrating autonomy …

CurveSLAM: utilizing higher level structure in stereo vision-based navigation
Existing approaches to visual Simultaneous Localization and Mapping (SLAM) typically utilize points as visual feature primitives to represent landmarks in the environment. Since these techniques mostly use image points from a standard feature point detector, they do not explicitly map objects or …

Learning-based cooperative perception and control for multi-robot systems
… onboard monocular cameras. We train a GNN-based visual navigation policy, guiding a mobile robot to a target without requiring calibration. We then combine the insights on control and perception and introduce a cooperative, multi-robot visual spatial foundation model for decentralised perception …

Adaptive modality selection for navigation systems
… these people must perform often require intense visual attention, such as scanning an area for threats or targets, conventional visual navigation systems (map-based GPS displays) add to that visual workload and put users in danger of divided attention and failure to perform critical functions. …
