Full body model with txt file

Dear Anybody Team,

We are using a marker free motion analysis system that ouputs joint angles in .txt format. Our marker free system output all the joint angles required for running the full body anybody model. We are using AnyKinEqInterPolDriver to run the model. Our model loads and run fine. But sometimes the motion is not very smooth. Is there anything that can be done to improve the model movement? Can we do parameter optimization when we are moving models using .txt files?

Your advise will be greatly appreciated.

Hi Ashish,

If the joint angles has not already been filtered you can use the filter classes in ANyBody for this, this may smooth the motion.

Please have a look at the class AnyFunButterWorth in the reference manual.

The parameter optimization will only work if you have a kinematic overdetermined system. If you are driving the model using joints angles only, this is not possible. The algorithm relies on the redundancy in the data to determine the unknown properties in the model.

Hi,anybody
I study the post and AnyScript Reference Manual ,and know the function AnyFunButterworthFilter may smooth the motion, but I can't use this function ,I want to know How to use this function with txt file . I study the GaitWaughan model but can not find this function.
The AnyBody is 5.3
thanks for you help
Best regards

Hi yangyang,

Please have a look in the reference manual on the AnyFunButterworthFilter
object. In the bottom of the object description page there is a small example on how to use the filter.

The example displays using the filter on some sample data.

In your case i would use the AnyInputFile to read in the data, once you have done this you can use the example further on.

Best regards
