OpenSense- single sensor rotation

Post by Therese Parr » Tue Apr 12, 2022 7:13 am

I have an OpenSense IMU model that seems like it is running into issues because one single sensor needs to be rotated in relation to the set. Is it possible to rotate a single sensor? I cannot find the option on the GUI (only can rotate all sensors in relation to OpenSense coordinate system).
If there's not a way in the GUI, is there an example MATLAB code that can be implemented in the OpenSense_CalibrateModel or the OpenSense_OrientationTracking? For this, I only see a rotation of Vec3, which is the whole set again.

Thanks in advance for the help!

You can adjust the "Rotation" property for the IMU in the GUI. For instance, using the OpenSense example files, the femur_r_imu can be adjusted as seen below:

Note that I had to save the model and load it back in to see the Rotation or Translation changes take place in the GUI.
