iphone 6s camera calibration parameters

Question

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?

Answer 1

所有这些参数都可以通过固有的校准过程进行计算，该过程可在Matlab相机校准工具箱或OpenCV库中获得。

Answer 2

尽管使用opencv，matlab应用程序或matlab工具箱进行的校准过程肯定可以正常工作，但我必须指出，由于制造质量控制的惊人性，iphone上的相机几乎是相同的（焦距相同，失真相同等）。
