PO-GVINS: A Tightly Coupled GNSS-Visual-Inertial Navigation Framework Using Pose-Only Representation

ICRA 2026poster

Accurate and reliable positioning is essential for perception, decision-making, and other high-level applications in autonomous driving, autonomous aerial vehicles, and intelligent robotics. Due to the inherent limitations of standalone sensors, integrating heterogeneous sensors with complementary c…

Thinking in Structures: Evaluating Spatial Intelligence through Reasoning on Constrained Manifolds

ICML 2026poster

Spatial intelligence is crucial for vision--language models (VLMs) in the physical world, yet many benchmarks evaluate largely unconstrained scenes where models can exploit 2D shortcuts. We introduce SSI-Bench, a VQA benchmark for spatial reasoning on constrained manifolds, built from complex real-w…
