pyCGM2.Model.modelDecorator.VCMJointCentre

pyCGM2.Model.modelDecorator.VCMJointCentre(HalfJoint: float, JointMarker: ndarray, TopJoint: ndarray, StickMarker: ndarray, beta: float = 0)

Calculates joint center according to Vicon Clinical Manager method.

Parameters:

• HalfJoint (float) – Radius of the joint.

• JointMarker (np.ndarray) – Joint marker trajectory for a specific frame.

• TopJoint (np.ndarray) – Proximal joint center trajectory for a specific frame.

• StickMarker (np.ndarray) – Lateral marker trajectory for a specific frame.

• beta (float, optional) – Rotation angle offset. Defaults to 0.

Returns:

np.ndarray – Coordinates of the joint center.
