A Procedure for Automatically Estimating Model Parameters in Optical Motion Capture [PDF]
Procedings of the British Machine Vision Conference 2002, 2002 Abstract Model-based optical motion capture systems require knowledge of the position of the markers relative to the underlying skeleton, the lengths of the skeleton's limbs, and which limb each marker is attached to. These model parameters are typically assumed and entered into the system manually, although techniques exist for calculating some of ...

Measurements of cervical range of motion using an optical motion capture system: Repeatability and validity. [PDF]
Exp Ther Med, 2019 The current study aimed to assess the repeatability and validity of cervical range of motion (CROM) measurements using an optical motion capture system (OMCS), compared with a CROM device. A total of 20 healthy volunteers were selected and enrolled in the current study after informed consent was received.

Validating Knee Varus Alignment Measurements Using Markerless Motion Capture
Geriatrics, 2023 This study aimed to determine the validity of specific knee varus alignment measurement methods. We measured the femorotibial angle (FTA) using radiography and optical motion capture and validated the FTA measurement using markerless motion capture.

Skeletal Parameter Estimation from Optical Motion Capture Data [PDF]
2005 IEEE Computer Society Conference on Computer Vision and Pattern Recognition (CVPR'05), 2004 In this paper we present an algorithm for automatically estimating a subject’s skeletal structure from optical motion capture data. Our algorithm consists of a series of steps that cluster markers into segment groups, determine the topological connectivity between these groups, and locate the positions of their connecting joints.
