Placement Yellow-Dot Red-Arrow Sanity Dataset
This is a LeRobot-format one-episode sanity export derived from local HDF5 placement data.
It uses source recording episode_00201.hdf5, one of the five episodes newer
than the existing 197-episode placement export.
Dataset size:
- episodes: 1
- frames: 259
- videos: 3
- export fps: 100
- frame stride from 100 Hz source: 1
- source episode index: 201
Source goal label:
- full-resolution target:
(564.0, 223.0)px - 224x224 overlay target:
(98.7, 81.025)px - image-space orientation:
0.42662749radians
Instruction:
move the connector to the yellow dot and match the red arrow orientation
The overhead video is rendered from the raw HDF5 overhead camera frame with an anti-aliased red arrow and yellow source dot plotted from HDF5 metadata:
placement/episode_target_image_xy_pxplacement/episode_target_theta_rad
No green-pixel detection is used. The 1280x800 source image is mapped to a 224x140 view with 42 px vertical padding inside the 224x224 LeRobot video frame.
Timing:
metadata.source_fpsstores the source recording rate from HDF5, normally 100 Hz.metadata.export_fpsand top-levelfpsstore this dataset's export rate.metadata.frame_stridestores the source-frame stride used for export.source.action_time_sstores the original source time for the retained frame.timestampstores the LeRobot export timestamp.
