Data Format
We provide data in a convenient format .hdf5 as well as .raw. The hdf5 format contains the followings:
$ h5ls -r 250220_121732/prophesee0/events.hdf5
/ Group
/raw_events Group
/raw_events/p Dataset {2076982/Inf}
/raw_events/t Dataset {2076982/Inf}
/raw_events/x Dataset {2076982/Inf}
/raw_events/y Dataset {2076982/Inf}
/trigger Group
/trigger/t Dataset {562/Inf}
/trigger/type Dataset {562/Inf}
'raw_events':'x': x coordinate (height).'y': y coordinate (width).'t': Timestamp in microsec.'p': Polatiry, 0 is negative and 1 is positive.
'trigger':'type': Sync trigger type, 1 indicates ON.'t': Timestamp in microsec.
RGB data is stored in mp4 file. The timing of the frames is the first trigger of every three ON triggers.
Annotation bounding boxes are provided as annotation.yaml in each sequence with CVAT v1.1 format.
The annotation coordinates are in the event camera image plane, and (x, y) corresponds to (width, height) from the top-left.
The annotations are at every ON trigger timing.

The OptiTrack marker is attached on top of the stereo camera, hence there is a few (5-10) cm offset between the true pose of the cameras and the GT pose from OptiTrack.
The camera pose is provided as 4-by-4 matrices (R, T) in .npz file format.
LED positions are given in references folder. Each json file stores the LED IDs in the 3D coordinate (same as the camera pose). The unit is in meter.
