Evaluation of Vision-Language Models Across Diverse Coastal Environments
Seth Knoop, Chad R. Samuelson, Gabriel R. Slade +2
Vision-language models (VLMs) enable robotic per- ception by associating visual observations with natural-language concepts. Yet their performance in coastal environments remains l…
Open-Set 3D Scene Graphs for Field Robotics: An Outdoor Case Study
Chad R. Samuelson, Gabriel R. Slade, Joshua G. Mangelson
Three-dimensional scene graphs (3DSGs) have emerged as a promising approach for building geometrically grounded, semantically informed, hierarchical general-purpose maps to support…
Terra: Hierarchical Terrain-Aware 3D Scene Graph for Task-Agnostic Outdoor Mapping
Chad R. Samuelson, Abigail Austin, Seth Knoop +4
Outdoor intelligent autonomous robotic operation relies on a sufficiently expressive map of the environment. Classical geometric mapping methods retain essential structural environ…
Towards Terrain-Aware Task-Driven 3D Scene Graph Generation in Outdoor Environments
Chad R Samuelson, Timothy W McLain, Joshua G Mangelson
High-level autonomous operations depend on a robot's ability to construct a sufficiently expressive model of its environment. Traditional three-dimensional (3D) scene representatio…
