Auto calibration with OpenCV 3?

Question

I am trying to do a dense 3d reconstruction project using openCV.

I am receiving a series of images from an unknown camera and so I cannot use the chess board method to find the intrinsic parameters of the camera. and so I must do auto calibration.

I saw that openCV has some methods for auto calibration such as focalsFromHomography() from this page.

After I find the features, match them and find the fundamental matrix is there a way I can calibrate the unknown cameras by doing auto-calibration (preferably by using OpenCV 3 for c++)?

Answer 1

OpenCV has an example called "stitching_detailed.cpp" that uses autocalibration, it helped me, maybe it helps you
