iphone 6s camera calibration parameters

How can I get camera calibration parameters for iphone 6s? I need the following intrinsic parameters:

Cam_fx: normalized focal length in x

Cam_fy: normalized focal length in y

Cam_cx: normalized camera center in x

Cam_cy: normalized camera center in y

Cam_s: normalized distortion factor

I tried using the PTAM camera calibration process but im getting some errors. Can anyone please suggest me some other way?

"I'm getting some errors" is not very helpful. Internet provides plenty of information and solutions to your problem. – Piglet

All these parameters can be calculate with an intrinsic calibration process, which is available in either Matlab Camera Calibration Toolbox or OpenCV library.

Though a calibration process using opencv, matlab app, or matlab toolbox surely works, I have to point out that cameras on iphone are almost IDENTICAL (same focal length, same distortion, and so on), due to maybe the astonishing manufacturing quality control.
