Position tracking with IMU

[Newguy]

Hello everyone.

Currently, I am using a BHI360 to derive readings for the sensor's position relative to its initial position (where it was first turned on).

I have adopted the double integration method with a highpass filter to filter out acceleration readings when the sensor is stationary.

The resulting distance reports are very poor, as velocity never goes down to 0, despite the acceleration showing a great decrease.

The velocity and distance should output as can be seen in the following screenshot:

Did anyone have experience working on this type of assignment? What could be done to report position reliably using an IMU.

If it's not possible, are there other alternatives to this problem?

Hi Newguy,

You can calibrate the accelerometer and gyroscope before, and test it again.
