PLANA3R framework enables zero-shot metric 3D reconstruction using planar splatting

Researchers have developed PLANA3R, a novel framework for metric 3D reconstruction of indoor scenes using planar primitives. This pose-free approach leverages Vision Transformers to identify sparse planar structures, estimate camera poses, and learn geometry through planar splatting. Unlike previous methods, PLANA3R trains without explicit 3D plane annotations, utilizing only depth and normal annotations on large-scale stereo datasets. The system demonstrates strong generalization across various indoor environments for tasks like 3D surface reconstruction, depth estimation, and relative pose estimation, also enabling accurate plane segmentation.
