Reasmory: 3D Reconstruction as Explicit Memory for VLMs Spatial Reasoning

arXiv:2606.00963v1 Announce Type: cross Abstract: Vision-Language Models (VLMs) exhibit emerging spatial reasoning capabilities, yet they remain unreliable on tasks requiring precise spatial understanding, such as viewpoint reasoning, directional comparison, and distance estimation. In multi-view images and monocular videos, relevant spatial cues are often sparse and distributed across redundant observations, making them difficult to organize and exploit. Reconstruction-based Vision Foundation Models (VFMs) offer a natural way to aggregate such observations into explicit spatial memory, such a

Why this matters
Why now

The continuous evolution of Vision-Language Models (VLMs) is pushing the boundaries of spatial reasoning, and this research addresses a critical gap in their current capabilities.

Why it’s important

Improving precise spatial understanding in VLMs is crucial for real-world applications in robotics, autonomous systems, and advanced AI agents, which require robust environmental context.
