A new dataset, HOT3D, provides over 833 minutes of egocentric, multi-view, hardware-synchronized videos of hands and objects with high-fidelity 3D ground truth. Experiments show multi-view approaches significantly improve accuracy for 3D hand pose tracking and 6DoF object pose estimation compared to single-view methods.
Key insights
- Multi-view egocentric data consistently provides superior accuracy and robustness compared to single-view data for 3D hand and object tracking tasks.
- Fusing information from synchronized multiple cameras aids 3D reasoning, helps overcome domain gaps in training data, and handles occlusions more effectively.
- Precise 3D localization of unknown in-hand objects is achievable through stereo matching of visual features, outperforming monocular depth-based approaches.
