    there is an example somewhere for the cil version that has done this with opencv.

    I think this was feature that was going to be bought into rc directly. but i haven't heard anything about that for a while.

    Hmm, pretty sure I answered this post...   anyway...

     

    Well done!  :-)

    Does this require the CLI version or is it an external little tool? And which Tags are you using?

    I am very interested! Any chance you would be willing to share it?

    Your distortion grid looks a bit worrying though...  ;-)

    ...its an external tool (using ArUco markers which are very well supported in OpenCV) producing a control point *.csv.

     

    Using four CP's per marker was not very stable distortion-wise, I now compute the centre point of every quadrilateral and things are looking much better:

    Nice!

    So you input the images and you get a point list which you then import into RC?

    ...exactly. In addition the tool produces a marked version of each image with a distinctive filename to check if the markers are found correctly:
