Calibration Study

Hi,
I have a question about calibration studies. Tutorial on
http://www.anybodytech.com/684.0.html talks about a “cheap and dirty” muscle
calibration which seems to be a dynamic calibration. But I could not make it
work in the example file from the website. As described in the document, i
looked for “MuscleCalibrationStudy” after loading the model but did not find
any such study in there. I have used static calibration, but never used this
dynamic calibration.

Does this “cheap and dirty” calibration goes through the whole motion (as in
inverse dynamics) or uses just the first frame of data to calibrate?

Can you please upload a sample model to describe this sort of calibration?
Or explain if I am missing the point here.

Thanks
Prabhav

Hi Prabhav,

Sorry, the tutorial refers to a old version of AnyBody. Thanks for bringing
this to our attention.

Now you have to specify a Calibarationstudy e.g.

AnyBodyCalibrationStudy CalibrationStudy = {

AnyFolder &Model = .MyModel;

nStep = 1;

}; // End of study

which will do the calibration. Basically this can do the same as the “Cheap
and Dirty” approach, you have to e.g. set nStep = 10.

For further documentation please refer to the Calibration Studies tutorial.

Best regards,

Sebastian
