Local and Global Skeleton Fitting Techniques for Optical Motion Capture [PDF]
, 1998 Identifying a precise anatomic skeleton is important in order to ensure high quality motion capture. In this paper we discuss two skeleton fitting techniques based on 3D optical marker data. First a local technique is proposed based on relative marker trajectories. Then it is compared to a global optimization of a skeleton model.

Analysis of accuracy in optical motion capture – A protocol for laboratory setup evaluation [PDF]
Journal of Biomechanics, 2016 Abstract Validity and reliability as scientific quality criteria have to be considered when using optical motion capture (OMC) for research purposes. Literature and standards recommend individual laboratory setup evaluation. However, system characteristics such as trueness, precision and uncertainty are often not addressed in scientific reports on 3D ...
