imu: float_sigma_filter before kalman filtering #11

Closed gauteh closed 2 years ago

gauteh commented 2 years ago

is this necessary?

jerabaul29 commented 2 years ago

I was doing this because i) I was reading from the 9dof at a higher rate than I could run the Kalman filter, ii) I did not want to loose any information, iii) now and then I saw an outlier value. I think this is not critical and can likely be ignored though.

(and even more, in the case of breaking waves, may be that this filtering would remove the "shocks" that you are interested in).

Ok. The imu does internal low pass filter to remove alias from the samples, so there should already be some smoothing.
