An Octave port of Camera Calibration Toolbox for Matlab (1st June 2017) (http://www.vision.caltech.edu/bouguetj/calib_doc/)
There is surprisingly very little code modifications required to make the original Matlab code to work in Octave (tested with 4.4.0). I only had to comment out usage of BackingStore
set(fig_number,'Units','points', ...
%'BackingStore','off', ...
I've tested with single camera and stereo calibration. The GUI elements in Octave are usable, though rendering isn't always 100% perfect. I found Octave GUI can be a bit quirky at times, might be related to my choice of using i3 tiling windows manager.
