Muovi+ IMU sensor
Cita da analy su 19 Aprile 2024, 11:53Hello,
I am planning on utilizing the IMU sensor, which is embedded on the MUOVI+ probe, in order to describe the movement of Center of Mass of the body during dynamic movements. I am mostly interested on displacement of vertical and horizontal axis. Altough there is a description on the user manual I am having hard time to digest which channel corresponds to each axis. Could please provide me more information about which channel of the quaternion is appropriate to use.

The IMU sensor of the Muovi+ probe give you the data in form of quaternions, you will see those 4 channels during the acquisition: q0, q1, q2 and q3. You can use them to calculate the Euler angle starting from the quaternions information, Matlab provide a built-in function that does that.
Example:
quat = quaternion([0.7071 0.7071 0 0]);
eulerAnglesRandians = euler(quat,"ZYX","frame")One thing to notice: you cannot go back from quaternions to 9-axis inertial signal (3 gyroscope, 3 accelerometer, 3 magnetometer).
