Hi,
I am doing a kinematics analysis based on C3D motion capture data.
The human model consists of head, thorax, right arm, and pelvis.
For the last my analysis, the motion capture data have markers only on right arm and thorax. And I could get a quiet satisfying result.
This time, I used markers on head additionally and did same operation.
However, I saw a message as following when I was on the motion and optimization analysis process.
- Calculating a new search direction (Operation: Main.Studies.KinematicStudyForParameterIdentification.Kinematics):
Kinematic parameter analysis failed : there are 14 design variables but only 13 independent associated optimality conditions
It did not stopped by any errors, and the analysis result text files were created successfully. But I don’t think that the kinematic analysis result is reliable with those messages.
In my script, additional driver of 3 dof for pelvis was integrated in order to compensate missing dofs due to absence of pelvic markers. And the pelvis is located on a proper position by entering its coordinate manually.
Thanks.
