Hello,
I have motion capture data from a inertial measurement system as angles in txt-files and want to import them in AnyBody in the FreePostureMove-Model.
Because the movement is not right when I import the data, I think I have to rotate the coordinate systems of each joint. I put an example from the left shoulder in the attachment.
If I understood this image right, I have to use the first sub-image.
So I tried this at the interface:
AnyFolder &gh=…Seg.Humerus.gh;
gh={
AnyRefNode RefNode = {
ARel=.ARel*{{0,0,1},{0,…Sign*-1,0},[{…Sign1,0,0}}RotMat(-90pi/180,y)RotMat(-90pi/180,x);
};
but this seems not right.
In addition, at my mocap system the definition of the direction of the movement is the other way round than at AnyBody: Flexion<0° and Extension>0°.
Maybe someone can help me with my rotational problem.
Kind regards
Julika
