Abstract

We introduce a self-supervised framework for learning joint visuospatial representations from RGB-D observations. While modern vision foundation models are trained almost exclusively on RGB images, many embodied systems have access to explicit depth sensing, which provides geometric information that monocular inputs cannot recover. Our method integrates depth-derived geometric priors with a visual backbone through inter-patch and intra-patch fusion, enabling the model to encode both appearance and spatial structure efficiently. The resulting representation shows promising improvements on 3D awareness while preserving semantic transfer: it outperforms prior methods of comparable scale on multiple 3D geometry benchmarks, and remains competitive when probed for standard RGB-D semantic segmentation tasks.

Qualitative Results

Architecture

DINOcular architecture
DINOcular integrates depth-derived geometric priors into a visual backbone through lightweight intra-patch early fusion and inter-patch 3D RoPE, jointly encoding appearance and spatial structure.

Training

DINOcular self-supervised training setup
Model learns joint visuospatial representations from RGB-D observations: semantics from self-distillation, spatial from multiview correspondence loss.
