Hello everyone, I am a student in engineering school in Paris and I am currently working on IMU sensors. My goal is to obtain the displacement of the sensor with a high precision either for a displacement of a few centimeters or for small vibrations. I have already used different methods such as double integrations, the use of filters, 'detrend' functions, denoise or even through the time domain ... Unfortunately I still observe drift in and bias in my speed and displacement values. I am sending you attached the sensor values ​​(acceleration, angular speed and magnetometer) as well as a photo of the speed values ​​that I get where you can see drift.
Thank you in advance for your help

Hello,
Currently I use an IMU sensor to define its positioning. I am using a code on MATLAB but I don't have the desired results yet.
I would like to know where you got to in your work.
