IPhone 5s camera calibration options

Question

I was wondering if anyone has any reliable internal or external settings that they would like to share with the iPhone 5s camera? I work in OpenCV and would like to disable my images before processing. I am working on the calibration code myself, but the end results are pretty painful at this point. If anyone has clean links to C ++ code, I would appreciate that too. I tried in parts to collect something from old textbooks, and it is not so hot.

As I understand it, I think I'm looking for parameters such as fx, fy, cx, cy, as well as 5 distortion parameters (k1, k2, k3, r1, r2). Although I know that each camera is a unique and beautiful snowflake, I just need to think that as a reference there should be some stable links to these values ​​for this particular camera.

Thank you all for your help over the years.

Answer 1

Check the samples folder in the OpenCV directory. I used a Python script, but of course there is a C ++ version .

Answer 2

As Adi Shavit said, the parameters of extrasism can only be determined by relativity, and another coordinate system. Moreover, I believe that the distortion coefficients are different for each camera chip, and there is no general way to find them out without calibration.
