Determining IMU placer rotation values
Posted: Wed May 25, 2022 9:16 am
Hello,
I am trying to determine how to put the rotation values into IMU placer. I am following the webinar on Opensense and have questions regarding the same.
1) When using preview sensor data option on placement_orientation.sto, the axes are very random. How was it calculated to rotate about -90 degree on X axis? How do you use the preview sensor data option to calculate the angle of rotation?
2) Are we trying to rotate the IMU space to Opensim space similar to marker based systems or how do we calculate the rotations? How is the the placement orientation related to IMU space and Opensim space?
Thanks
