plates_all

Raw plate captures for the stringman visual servoing dataset: what the gripper camera saw, stored exactly as it came off the robot. Nothing here is matted, keyed or composited.

kind runs plates
fingerplates 3 4536
floorplates 15 23142
objectplates 39 60297

Each run is a parquet file of encoded frames, or a .ts video plus a .jsonl telemetry track, described by one line of manifest.jsonl. Read it with nf_robot.ml.visual_servoing.plates, and pull it into a local collection with:

python -m nf_robot.ml.visual_servoing.merge_plates --into plates --from naavox/plates_all

Mattes and synthetic frames are derived from these by finger_matte.py, object_matte.py and synth_frames.py, whose thresholds are still being tuned - so they are rebuilt from this, never stored alongside it.
