Сalibration from a set of pictures

[SKioresku]

Is it possible to calibrate using a set of pictures like the kalibr does?

Yes it is possible but not documented.

The board_extractor can also extract from a set of PNG images. look here

The filenames have to be the frametime in nanoseconds here

There is also a python script that runs calibration on a Mynteye camera. here I will see if I can upload that as an example.
