I am acquiring data from mobile sensors (accelerometer, gyroscope, GPS, etc.) while driving a car in order to analyze the driver’s acceleration.
The phone is set in an arbitrary position inside the car, that’s why I need to reorient the accelerometer axis to align with the car axis.
I found an article mentioning a virtual reorientation algorithm for this matter. But I am not getting how they used GPS to calculate the post-rotation and how they monitored the pre-rotation angles: Conference Paper Nericell: Rich monitoring of road and traffic conditions usi...
Is there an application that can automatically do the transformation?
Any advice or even an alternate way of doing this would be greatly appreciated.
Please refer the following journals. The whole process is explained in detail.

Farah Kobeissy a simple and widely used formula in the area for axis reorientation can be found in this article:

However, there are some considerations. Currently, I develop research with inertial sensors (accelerometer, gyroscope) in vehicles to generate exteroception (recognize the external environment) and proprioception (recognize the attitudes of the vehicle). I did a systematic literature review that includes the axis reorientation methods, if you want to read the article it is available free of charge at this link:

In general, there are two ways to apply these sensors inside a vehicle: through controlled positioning or axis reorientation. In this paper you will find:
- Section Inertial Sensor Reference Frames: a general explanation of the two methods mentioned above.
- Section Data Preprocessing Step: how each article employed these methods, with their customizations.
- Section Discussion and Conclusions: a general discussion of pros and cons for each method and when to apply.
I think reading the article might be interesting for you.
