We introduce the task of 3D object localization in RGB-D scans using natural language descriptions. As input, we assume a point cloud of a scanned 3D scene along with a free-form description of a specified target object. To address this task, we propose ScanRefer, learning a fused descriptor from 3D object proposals and encoded sentence embeddings. This fused descriptor correlates language expressions with geometric features, enabling regression of the 3D bounding box of a target object. We also introduce the ScanRefer dataset, containing 51,583 descriptions of 11,046 objects from 800 ScanNet scenes. ScanRefer is the first large-scale effort to perform object localization via natural language expression directly in 3D.

  1. ACE-Brain-0.5: A Unified Embodied Foundational Model for Physical Agentic AI

    cs.RO 2026-07 conditional novelty 6.0 of 10

    A single 8B backbone unifies spatial perception, decision making, navigation/manipulation, and progress estimation with SSR+ merging, reporting gains on most spatial benchmarks and competitive action/progress results.

  2. IR3D-Bench: Evaluating Vision-Language Model Scene Understanding as Agentic Inverse Rendering

    cs.CV 2025-06 conditional novelty 6.0 of 10

    A benchmark that scores vision-language models by reconstructing the 3D scene behind an image as executable Blender code finds the models fail mainly on spatial precision, not tool usage.

  3. Embodied Spatial Intelligence: from Implicit Scene Modeling to Spatial Reasoning

    cs.RO 2025-08 conditional novelty 4.0 of 10

    The thesis demonstrates that combining implicit 3D scene representations with LLM-based reasoning, using text as an interface, yields strong performance on robotic perception and spatial language tasks.
