Tilt correction matrix in accelerometer calibration

Hello,

The tilt correction matrix is a rotation matrix to align the pitch and roll angles to the perpendicular plane of gravity so it can be considered as a change of basis or alignment matrix if, for example, the sensor frame is not aligned with the body frame.

I haven't been able to find in the sensor fusion documentation "when" and "where" in the filter this rotation matrix is computed. Does anybody have the answer?

 

thank you,
