Can someone provide me an example of how kalman filters can be used to estimate position of an object from 6DOF/9DOF IMU data. All examples I have seen just seem to find orientation of the object using ahrs/imufilter.

Hello
I have a question if you don't mind, I use data from an IMU sensor to determine positioning in the civil engineering field. I am using MATLAB code to do this. For the moment I don't have the right result compare by the real case.
Did you have a satisfactory result according to your studies?

hello,
you need to integrate the accelerometers if you want to calculate linear positions. this will be subject to quadratic error propagation over time, so it is necessary to periodically reset the integrator.
it works like this: you use the orientation calculated from the fusion algorithm (kalman filter or some other algorithm) to rotate locally measured accelerations into the world frame. then you subtract nominal gravity, then you integrate twice.
good luck,
Martin

HI linda , have you finally found the solution of the wrong position problem ? Beacause I found myself in the same problem for my thesis.
