Update!

I tried with another video, and it worked!

I still need to figure out why, but the intrinsic and extrinsic configurations are ok for all trials.

I hope I can get back here with the augmented TRC file.

Best regards.

About the camera model, I'm using the same metadata file from the OpenCap session. So it is iPhone14,7 for this data. Is that it? Printing CamParamDict I think is right. The inial values are the same, the last ones are different (I suppose this first ones are intrinsic values): {'Cam0': {'distortion...

Thanks a lot Scott, As I mentioned, I collected gait data with OpenCap online, downloaded the files, and tried running everything locally. I'm using the already used (online) calibration file "cameraIntrinsicsExtrinsics.pickle". So, do you have any guess where to change the camera model in the avail...

Hello, everyone; I made some progress in trying to set up the pipeline to run locally. I'm just focusing on using the already available "cameraIntrinsicsExtrinsics.pickle" in the downloaded data from OpenCap, and redoing a pose estimation (creating the TRC file with augmented markers). So far I'm st...

Thanks, Mohammadreza!

Has anyone tried creating the configuration of the InducedAcceleration component with code?

Best regards.

UPDATE,

I took a leap of faith and tested in OpenSim 4.5, but I got the same behavior in OpenSim GUI.

Best regards.

UPDATE, To make it clearer: analise3 = osim.AnalyzeTool('analise.xml') iaa = analise3.getAnalysisSet().get(0) CS = iaa.updPropertyByName('ConstraintSet') CSo = CS.updValueAsObject() CS_obj = CSo.updPropertyByIndex(1) # <objects> constraintR = CS_obj.updValueAsObject(0) #<RollingOnSurface ... > const...

Hello Mohammadreza, I'm getting the same behavior in OpenSim 4.4. It is definitely a bug. When I load the .xml, the IAA field is changed, clearing the information about the bodies in RollingOnSurfaceConstraint. errorIAA.png And it happens as well if you load the .xml file using the API in Python. I ...

Great. That would be awesome. If I could suggest, I also tried creating the .sto file for all contact forces in the model, and it worked well. Just create the .sto remember to insert [force] [Cop] [torque] for all contact geometry using only the halfplane (changing the signs of forces and torques). ...

Great! And... It worked!!!! For everyone interested in IAA analysis with OpenSim API after a Moco simulation, here are my top tips: Create a ForceReporter file of your simulation Follow the code in https://github.com/opensim-org/opensim-core/blob/main/OpenSim/Moco/MocoUtilities.cpp#L310 , but change...
