pySpatial: Generating 3D Visual Programs for Zero-Shot Spatial Reasoning

ICLR 2026poster

Multi-modal Large Language Models (MLLMs) have demonstrated strong capabilities in general-purpose perception and reasoning, but they still struggle with tasks that require spatial understanding of the 3D world. To address this, we introduce pySpatial, a visual programming framework that equips MLLM…

Point2Graph: An End-to-End Point Cloud-Based 3D Open-Vocabulary Scene Graph for Robot Navigation

ICRA 2025

Current open-vocabulary scene graph generation algorithms highly rely on both 3D scene point cloud data and posed RGB-D images and thus have limited applications in scenarios where RGB-D images or camera poses are not readily available. To solve this problem, we propose Point2Graph, a novel end-to-e
