+ # Placement Yellow-Dot Red-Arrow Sanity Dataset
12
+
13
+ This is a LeRobot-format one-episode sanity export derived from local HDF5 placement data.
14
+ It uses source recording `episode_00201.hdf5`, one of the five episodes newer
15
+ than the existing 197-episode placement export.
16
+
17
+ Dataset size:
18
+
19
+ - episodes: 1
20
+ - frames: 259
21
+ - videos: 3
22
+ - export fps: 100
23
+ - frame stride from 100 Hz source: 1
24
+ - source episode index: 201
25
+
26
+ Source goal label:
27
+
28
+ - full-resolution target: `(564.0, 223.0)` px
29
+ - 224x224 overlay target: `(98.7, 81.025)` px
30
+ - image-space orientation: `0.42662749` radians
31
+
32
+ Instruction:
33
+
34
+ > move the connector to the yellow dot and match the red arrow orientation
35
+
36
+ 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:
37
+
38
+ - `placement/episode_target_image_xy_px`
39
+ - `placement/episode_target_theta_rad`
40
+
41
+ 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.
42
+
43
+ Timing:
44
+
45
+ - `metadata.source_fps` stores the source recording rate from HDF5, normally 100 Hz.
46
+ - `metadata.export_fps` and top-level `fps` store this dataset's export rate.
47
+ - `metadata.frame_stride` stores the source-frame stride used for export.
48
+ - `source.action_time_s` stores the original source time for the retained frame.
49
+ - `timestamp` stores the LeRobot export timestamp.
