Any Resolution Any Geometry: From Multi-View To Multi-Patch
Summary
The Ultra Resolution Geometry Transformer (URGT) is a novel multi-patch transformer designed for monocular high-resolution depth and normal estimation, addressing the trade-off between local detail and global consistency in 3D scene understanding. It adapts the Visual Geometry Grounded Transformer (VGGT) by partitioning a single high-resolution image into patches, which are then augmented with coarse depth and normal priors from pre-trained models. These patches are jointly processed in a single forward pass, using cross-patch attention to enforce global coherence and enable long-range geometric reasoning. The URGT also incorporates a GridMix patch sampling strategy during training to enhance spatial robustness and improve inter-patch consistency. This method achieves state-of-the-art results on UnrealStereo4K, significantly improving depth and normal estimation.
Key takeaway
For Computer Vision Engineers developing high-resolution 3D scene understanding systems, URGT offers a robust solution for joint depth and normal estimation. Its multi-patch architecture and cross-patch attention mechanism provide superior detail and global consistency, reducing AbsRel to 0.0291 and RMSE to 1.31 on UnrealStereo4K. Consider integrating similar transformer-based multi-patch approaches to improve geometric accuracy and scalability in your projects.
