The D1 dataset is exported from the D1 headset multi-camera human motion capture system developed by Delta Intelligence. Each recorded episode contains synchronized multi-view video streams and whole-body skeleton and headset pose data. The dataset supports research and development in: - Human detection, keypoint detection, and pose estimation - Egocentric visual observation and synchronization checking - Imitation learning, behavior cloning, and embodied intelligence model training - Visual-inertial odometry and SLAM-related observation analysis Unlike purely third-person datasets, D1 combines egocentric RGB and fisheye views with global whole-body skeleton and headset pose states, making…
