Wide-Area Geolocalization with a Limited Field of View Camera in Challenging Urban Environments
Lena M. Downes, Ted J. Steiner, Rebecca L. Russell +1
Cross-view geolocalization, a supplement or replacement for GPS, localizes an agent within a search area by matching ground-view images to overhead images. Significant progress has…
Vision-Based Terrain Relative Navigation on High-Altitude Balloon and Sub-Orbital Rocket
Dominic Maggio, Courtney Mario, Brett Streetman +2
We present an experimental analysis on the use of a camera-based approach for high-altitude navigation by associating mapped landmarks from a satellite image database to camera ima…
Wide-Area Geolocalization with a Limited Field of View Camera
Lena M. Downes, Ted J. Steiner, Rebecca L. Russell +1
Cross-view geolocalization, a supplement or replacement for GPS, localizes an agent within a search area by matching images taken from a ground-view camera to overhead images taken…
City-wide Street-to-Satellite Image Geolocalization of a Mobile Ground Agent
Lena M. Downes, Dong-Ki Kim, Ted J. Steiner +1
Cross-view image geolocalization provides an estimate of an agent's global position by matching a local ground image to an overhead satellite image without the need for GPS. It is…
Lunar Terrain Relative Navigation Using a Convolutional Neural Network for Visual Crater Detection
Lena M. Downes, Ted J. Steiner, Jonathan P. How
Terrain relative navigation can improve the precision of a spacecraft's position estimate by detecting global features that act as supplementary measurements to correct for drift i…
Collision Probabilities for Continuous-Time Systems Without Sampling [with Appendices]
Kristoffer M. Frey, Ted J. Steiner, Jonathan P. How
Demand for high-performance, robust, and safe autonomous systems has grown substantially in recent years. These objectives motivate the desire for efficient safety-theoretic reason…
Towards Online Observability-Aware Trajectory Optimization for Landmark-based Estimators
Kristoffer M. Frey, Ted J. Steiner, Jonathan P. How
As autonomous systems increasingly rely on onboard sensing for localization and perception, the parallel tasks of motion planning and state estimation become more strongly coupled.…
Efficient Constellation-Based Map-Merging for Semantic SLAM
Kristoffer M. Frey, Ted J. Steiner, Jonathan P. How
Data association in SLAM is fundamentally challenging, and handling ambiguity well is crucial to achieve robust operation in real-world environments. When ambiguous measurements ar…
Complexity Analysis and Efficient Measurement Selection Primitives for High-Rate Graph SLAM
Kristoffer M. Frey, Ted J. Steiner, Jonathan P. How
Sparsity has been widely recognized as crucial for efficient optimization in graph-based SLAM. Because the sparsity and structure of the SLAM graph reflect the set of incorporated…
