Xsens C3D marker protocol

[CDzialo (Christine Dzialo)]

Hi Darius,

Thank you for the files. Apologies for the delay, overall, the scaling of the BVH avatar looks incorrect, very long legs and very short torso...is this the true anthropometry of the subject?

For trials 1 and 2 you need to adjust the initial mannequin posture to better fit the initial position the avatar is in within the BVH file.

So within the TrialSpecificData.any files change KneeFlexion = 90 (both left and right) and then also change ElbowFlexion = 20 (both left and right). When I did this the model ran all the way through for me.

Trial 3 ran for me, what was the problem with this file for you?

For Trials 4-6, Something similar has been happening to some other users and we are currently trying to fix this. Here is a little bit more information about it:

AnyMoCap+Xsens - Error in Euler angle discontinuity filtering

Hi Marco, The problem appears to be that there are angular jumps in the BVH data. The AnyInputBVH object has filters which can be used to remove these jumps of e.g. 2pi or 1pi see the Rotation2PiFixOnOff or Rotation1PiFixOnOff objects. The error you get is because AnyBody is trying to apply this filter but while doing this it detects that the jumps on different rotations in the joint do not match perfectly and throws an error. I tried to load your file and disable the angular filtering of ju…
