Storing & getting the device orientation (yaw, pitch, roll) when taking a photo

Question

I want to take a photo and use the stored GPS coordinates and the orientation of the phone to do some calculations. How can I access that information?

Alternatively if there is an API to do that I could make my own app.

Answer 1

Of course! You can use Metadata viewer to see the GPS coordinates and other information of your photos. Android has Handful of APIs for anything you want. If you a developer you can make use of that. Here is all you need.

• Tutorial to get yaw, pitch, roll in android.
• Simple Camera API tutorial
• Google documentation about accelerometer api :)

Answer 2

This is one of those problems that I believe requires a documented standard: the same reason every platform trivially accesses the GPS location of a photo is because of EXIF and it's standardized tags.

EXIF is not user-extensible, and side car files are too namespace-y (proprietary).

Unless I'm wrong about there not being a standard place for Euler angles or even the quaternion that establishes device attitude.
