SurfSLAM: Sim-to-Real Underwater Stereo Reconstruction For Real-Time SLAM
Onur Bagoren, Seth Isaacson, Sacchin Sundar +6
Localization and mapping are core perceptual capabilities for underwater robots. Stereo cameras provide a low-cost means of directly estimating metric depth to support these tasks.…
SLIM-VDB: A Real-Time 3D Probabilistic Semantic Mapping Framework
Anja Sheppard, Parker Ewen, Joey Wilson +6
This paper introduces SLIM-VDB, a new lightweight semantic mapping system with probabilistic semantic fusion for closed-set or open-set dictionaries. Advances in data structures fr…
A Stochastic Approach to Terrain Maps for Safe Lunar Landing
Anja Sheppard, Chris Reale, Katherine A. Skinner
Safely landing on the lunar surface is a challenging task, especially in the heavily-shadowed South Pole region where traditional vision-based hazard detection methods are not reli…
MarsLGPR: Mars Rover Localization with Ground Penetrating Radar
Anja Sheppard, Katherine A. Skinner
In this work, we propose the use of Ground Penetrating Radar (GPR) for rover localization on Mars. Precise pose estimation is an important task for mobile robots exploring planetar…
ShipwreckFinder: A QGIS Tool for Shipwreck Detection in Multibeam Sonar Data
Anja Sheppard, Tyler Smithline, Andrew Scheffer +5
In this paper, we introduce ShipwreckFinder, an open-source QGIS plugin that detects shipwrecks from multibeam sonar data. Shipwrecks are an important historical marker of maritime…
Field Report on Ground Penetrating Radar for Localization at the Mars Desert Research Station
Anja Sheppard, Katherine A. Skinner
In this field report, we detail the lessons learned from our field expedition to collect Ground Penetrating Radar (GPR) data in a Mars analog environment for the purpose of validat…
