• 03/2023: Initial release of the visualization Tool (SMPL-Scene Viewer) (v1.0)

Dataset

• 15 sequences of 12 human subjects in
• 10 scenes in urban environments (1k – 30k $m^2$)
• 100k+ frames multi-source data (20 Hz)
• including 2D / 3D annotations and 3D scenes; 7 km+ human motions.

Every human subject signed permission to release their motion data for research purposes.
