|
| Camera intrinsics are stored per frame as `observation.intrinsics.<camera>` |
| (flattened 3x3), and wrist-camera extrinsics as `observation.extrinsics.<camera>`. |
| Depth is 12-bit logarithmically quantized in the video stream; a lossless |
| first frame of each episode (RGB PNG + uint16 depth PNG + calibration JSON) |
| is archived under `meta/keyframes/` for pose estimation. |
|
|
| ## Usage |
|
|
| ```python |
| from lerobot.datasets.lerobot_dataset import LeRobotDataset |
| |
| dataset = LeRobotDataset("YzyLmc/unstack_yellow_blue") |
| print(dataset[0].keys()) |
| ``` |
