The is code to test filters on phone accelerometer data and to visualize the data.
This file simply applies various filters and looks at the output. Kalman, moving average and butterworth are included.
This is a visualization script. It uses the Andrid app found here: https://play.google.com/store/apps/details?id=de.lorenz_fenster.sensorstreamgps&hl=en and live streams
- raw acceleration data,
- filtered accleration data, and
- Either the G-forces applied, or the tilt angles.
Enjoy!
