I was wondering how to compute the tilt angle from raw accelerometer data?

From an accelerometer I convert the raw data to m/s/s but want to use the device as a tilt sensor for psuedostatic tilt measurements. I can't quite get this straight for all three measurement axes.

Hi jon,

You can use "imufilter" function in MATLAB to estimate the tilt, as shown in the example below. However, it requires the readings from both gyroscope and accelerometer.

openExample('shared_positioning/EstimateOrientationFromIMUDataExample')

You can refer to the following documentation to learn more about the "imufilter" function:

Hope this helps.
