Using Kinect as an input for OpenSim

[Khang Nguyen]

Hi all,

This is my first time using OpenSim and Kinect. I want to use data from Kinect like x,y,z coordinates as input data for OpenSim , so I can use built-in functions from OpenSim like inverse kinematics. But I want OpenSim input data from Kinect simultaneously (real life). Are there any ideas ?

Thank you in advance!

Kevin

This may be a good place to start....

Hi Kevin,

It's an old project of mine. It may need some changes to work with streaming, but I think it is a good start. Also, I dump the joint position to OpenSim trace files.

Thank you for your help!

However I have a new question here. Now I am using model arm26 with 3 markers data from Kinect. So I clicked on "Preview Experimental Data" to input the makers' data .trc file.The simulation run well. Then I use the "Inverse Kinematics " tool and import the same .trc file, then the markers are off from the shoulder, elbow and wrist positions.

I think I need to perform some scaling before running the Inverse Kinematics. But I do not know how.

Would you please give me some hints?

Is that what you need?

Hi,
In which type of movements have you used Kinect, I think Kinect is not at its best in case of level walking.
