I read also that for remove noisy is possible applicate a Kalman-Filter, now I'm very confuse :/ If i start to reading my data during the travel. When i finish i would to process my data, to obtain a final vertical displacement graph as i said, with only euler method i noticed that it is...

Thank you both for the answer. I'll try to follow your advice, I think that the result depends strongly from the error that I get to the base, as well as try as you said, I think to change approach, and then, or not to use the Euler method, or had read about the Fast Fourier Transformation (FFT).

It doesn't read zero perfectly when there is no acceleration (I think it's due to vehicle vibrations), but values which are very close to zero, as the recording is very high frequency (100Hz). The recording is done at the moment with the phone attached to the car dashboard.

Thanks, i drop the ##0.5 * ay + deltaT^2##. The result, however, seems to be almost equal as you have just told me. That I can not understand is whether applying the procedure, what you get is the actual car's vertical displacement or less. Graph I get is almost similar to what I posted before...

Thanks for the answer, but I could not even get the desired result, I try to explain better my problem. I register with a smartphone inside a vehicle, the data of the accelerometer, orientation and time. From the vertical acceleration signal like in the image: http://imgur.com/P0wf6pv They...

I'm doing a program for the simulation of some experimental data. The data is recorded by a device and that the register are the: - acceleration components along the (x, y, z), - time (starting from 0, and change of each recording Delta t), - orientation (azimuth, roll, pitch). My goal is to be...
