Question about marker data

Post by masahiro yokota » Tue Oct 02, 2018 1:42 am

Hello, everyone!

I have two questions about marker data.

1.I'd like to get .trc data from motion capture to execute scaling and IK.
I use kinect(xbox) and I have only 10 markers. In the opensim model such like gait2354, it use more makers.
To get accurate joint angle and simulation result, do I need to increase maker?

2.I confuse where should I attach markers. If it is possible to get accurate simulation result using only 10 markers, I think the result may be changed by attached marker place. If there are a manual where should I attach markers, could you tell me about one?

Thank you very much.

There is a Wiki page on data here; https://simtk-confluence.stanford.edu/d ... +Your+Data

There is a youtube video on Data collection, scaling, and IK here; https://www.youtube.com/watch?v=ZG7wzvQC6eU
