OTHER TIPS
- As a general rule, you must place enough markers on your subject to scale and track each body segment you will model. You need at least three non-collinear markers to track the 6 DOF motion (position and orientation) of a body segment.
- Try to place markers on anatomical locations that will have the least skin and muscle motion.
- There are several OpenSim model marker sets that you can use and adapt, including:
- Full-body model used for dynamic simulations of running by Hamner et al., 2010: https://simtk.org/project/xml/downloads.xml?group_id=516
