RRIS40 Test Dataset

This dataset is a set of spatially aligned and temporally synchronized records of random human movements from a marker-based motion capture system and eight video cameras. The main purpose of this dataset is to benchmark the 3D accuracy of any multi-camera human motion capture method.

Specifications

• 10 subjects
• total of about 0.1 million frames (8 images per frame) with raw 3D marker positions.
• 3D data from a marker-based motion capture system (Qualisys)
  • 200 fps
  • positions of 40+6 markers in TSV format (Labels and definitions of all markers can be found here)
• Data from RGB Video Cameras
  • 8 synchronized global shutter cameras
  • 1920 x 1200 resolution
  • 50 fps
  • h.264 encoding
  • intrinsic calibration parameters
  • extrinsic calibration parameters (in the Qualisys coordinate reference frame)
• Frame-level hardware synchronization is used between Qualisys’ Miqus sync unit and all the RGB cameras.
• The formulation to interpolate 3D marker positions at the center of frame exposure time and projection to the video frame is provided in the data viewer source code.

Organization

• Data from each subject is stored in one zip file such as SN123g.zip or FT321g.zip. Each zip file contains one or more record folders inside.
• Each record folder has the following structure
  • YYYY-MM-DD-HH-mm-ss/ is called a record folder which contains data from only one continuous record.
    • qualisys.tsv contains data from the marker-based motion capture system
    • metadata.pkl contains metadata on the video record
    • systemCalibration.pkl contains calibration parameters of all the video cameras
    • keepMarker{camera_id}.h264 contains encoded video content.
    • keepMarker{camera_id}.seek Do not remove this file.
    • frameInfo{camera_id}.dat Do not remove this file.
