News and Updates

More info is coming soon…
05/11/2023: Released a SAM-based tool for 2D mask generation and updated the data loader example.
04/2023: First part of the dataset V1.0 has released! (Dataset)
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.
