3D Dynamic Scene Graphs: Actionable Spatial Perception with Places, Objects, and Humans

Paper: Abstract: We present a unified representation for actionable spatial perception: 3D Dynamic Scene Graphs. Scene graphs are directed graphs where nodes represent entities in the scene (e.g., objects, walls, rooms), and edges represent relations (e.g., inclusion, adjacency) among nodes. Dynamic scene graphs (DSGs) extend this notion to represent dynamic scenes with moving agents (e.g., humans, robots), and to include actionable information that supports planning and de
