Vision-Aided Navigation using Tracked Landmarks
<p>This thesis presents vision-based state estimation algorithms for autonomous vehicles to navigate within GPS-denied environments. To accomplish this objective, an approach is developed that utilizes a priori information about the environment. In particular, the algorithm leverages recognizable …

Stochastic constraints for vision-aided inertial navigation
This thesis describes a new method to improve inertial navigation using feature-based constraints from one or more video cameras. The proposed method lengthens the period of time during which a human or vehicle can navigate in GPS-deprived environments. Our approach integrates well with existing …

Multiple hypothesis positioning algorithm for robust GPS-denied navigation
… techniques such as landmark navigation or vision-aided navigation can be difficult when there is limited prior position information. Therefore, the Multiple Hypothesis Positioning algorithm is developed in this thesis to provide robust positioning in GPS-denied navigation scenarios where …
