Articulated 3D Scene Graphs for Open-World Mobile Manipulation

Read the original on arXiv AI →

The paper introduces MoMa-SG, a framework that constructs semantic‑kinematic 3D scene graphs for articulated scenes using RGB‑D sequences. It segments interactions, tracks points robustly, estimates joint parameters in a single optimization, and associates objects with articulations to detect contained items. The authors also present the Arti4D‑Semantic dataset with 62 real‑world sequences and demonstrate the system’s effectiveness on a quadruped and a mobile manipulator.

Track2Art: Motion-Centric Articulated Object Model Recovery from 2D Point Trackers

Track2Art is a motion‑centric framework that recovers articulated object models from RGB‑D interaction videos by lifting 2D point tracks into 3D trajectories. It groups these trajectories into rigid‑part hypotheses and uses learned‑analytic reasoning to infer directed kinematic relations, joint types, and joint geometry. On the PartNet‑Mobility benchmark, it achieves 0.695 Point IoU and 0.410 end‑to‑end J@20 without requiring ground‑truth part counts or test‑time optimization.

MoSE3: Learning World-Space SE(3) at Every Pixel

MoSE3 is a feed‑forward model that predicts dense SE(3) motion—full 6‑DoF rigid transforms—at every pixel from monocular RGB video, providing rotation, translation, and grouping information simultaneously. It achieves this by jointly learning 3D point tracks and rigidity embeddings, then differentiably fitting transforms within soft rigid clusters. The authors also release Art‑Kubric, a large synthetic dataset with dense SE(3) and rigidity labels, and demonstrate state‑of‑the‑art performance on both rigid and articulated benchmarks, with strong generalization to real‑world videos.
