OpenDepth repurposes Image-to-Image (I2I) editing priors to improve monocular depth estimation in open-world conditions. By aligning shallow features in a Diffusion Transformer and adding a joint RGB reconstruction task, the method decouples environmental style from geometry, enabling robust depth inference across varied lighting and weather. The approach achieves new state‑of‑the‑art performance on standard and extreme weather benchmarks, maintaining structural integrity in zero‑shot settings.
The paper introduces Epipolar Distillation (EpiDistill), a method that transfers scale‑aware geometric priors from multi‑view models to monocular depth foundation models using Rectified Stereo Tokens. By preserving epipolar attention patterns, the single‑view model maintains geometric consistency without needing multi‑view inputs during inference. Experiments show significant improvements in zero‑shot metric depth estimation on challenging datasets such as ETH3D and DIODE, and the approach consistently boosts performance of state‑of‑the‑art ViT‑based models like UniDepthV2 and DepthPro.
