Promptable Encoder-Decoder with MHR
SAM 3D Body (3DB) employs a novel promptable encoder-decoder architecture, allowing user-guided inference through 2D keypoints and masks. Unlike prior work, 3DB utilizes the Momentum Human Rig (MHR), a new parametric mesh representation that explicitly decouples skeletal structure and body shape, offering richer control and interpretability. A shared image encoder feeds into separate decoders for body and hands, resolving optimization conflicts and enhancing overall accuracy.
Scalable Data Curation for Diversity
To overcome the scarcity of high-quality 3D supervision, 3DB uses a sophisticated data engine. This engine employs a VLM-based mining strategy to identify and route challenging in-the-wild images (unusual poses, occlusions, rare conditions) for annotation. This ensures unprecedented data diversity beyond laboratory settings, leading to superior generalization. The pipeline generates high-quality 3D human mesh annotations from 7 million images using multi-stage processes including manual keypointing, differentiable optimization, multi-view geometry, and dense keypoint detection.

User Preference Win Rate Against Strongest Baseline (NLF)
A large-scale human preference study involving 7,800 participants showed that 3DB consistently outperforms all baselines. Against the strongest baseline (NLF), 3DB achieved an 83.8% win rate in visual quality, demonstrating superior perceptual alignment with real-world images.
Transformative Impact on Embodied AI & Robotics
The robust full-body human mesh recovery provided by SAM 3D Body addresses critical limitations of existing HMR approaches, particularly in scenarios with challenging poses, severe occlusion, or uncommon viewpoints. This breakthrough enables more reliable 3D human understanding essential for advanced robotics (37, 32, 47) and biomechanics (36). For example, robots can now interpret complex human actions more accurately for safer human-robot interaction and rehabilitation applications. This opens new possibilities for training embodied AI agents in realistic, dynamic environments where precise human body understanding is paramount.
