This repository contains files related to a data set.

See recorder

Dataset content

  • Raw binary recordings (not published)
  • Events in AEDAT4 files
  • Coordinates in JSON files
  • HDF5 files with frames and coordinates with 1ms precision

Dataset structure

For each shape/tool for each transformation and for each recording we generate three files

  1. .hdf5 file without timestamps, containing the following keys
    • coordinates (as positions and quaternion in camera coordinates): $N \times (X, Y, Z, Q_X, Q_Y, Q_Z, Q_W)$
    • indices: $N \times (Polarity, X, Y)$
    • values: $N \times Count$
  2. events.aedat4: AEDAT4 formatted events (with timestamps)
  3. coordinates.json: JSON object with name(s) of shapes/tools, mapping to a list of 8-tuples: $(Timestamp, X, Y, Z, Q_X, Q_Y, Q_Z, Q_W)$
    • Timestamps in the coordinate files are synchronized with the timestamps in the events.aedat4 file.
