  • An Important Vicon question about joint angles

    Dear Researchers,

    I am using The Vicon Motion Tracking system for capturing human gait. I have
    come across one serious question. I am using my own model to put the markers
    on the subject's body. For each segment (for example upper arm), I use 3
    non-collinear markers to define a coordinate system. What I get as the
    output of the Vicon is a CSV file containing Rx, Ry, Rz of each segment
    either in terms of Euler angles YXZ or Helical axis .

    My question is how can I calculate flexition/ extension (in sagittal plane)
    of each joint i.e knee joint given Rx, Ry, Rz in terms of either YXZ Euler
    angles or Helical angles?

    I really appreciate your comments and help,

    Regards,
