Hi!

I'm having trouble with aruco::CvDrawingUtils::draw3dAxis and aruco::CvDrawingUtils::draw3dCube in aruco-3.1.11. The coordinate axis and the cube are offset from where they should be. However aruco::Marker::draw is good.

Thank you for ArUco.

JC

P.S: I am working in Windows 10 x64 with Visual Studio 2019.

    Yes, it is. I had calibrated the camera with aruco_calibration.exe several times and generated the .yml file. I got an error around 2 .

    However, to answer you I decided to repeat the whole process, and I got in calibrate an error of 0.6. And, with that new file, it works perfectly!

    Sorry for the inconvenience, and thanks for responding! :-) You can close the 'issue'.

    PS: I have suspicions about what could have happened... For some reason aruco_calibration.exe doesn't accept my video stream. So I have to generate a video, convert it to .mp4 and use it for calibration. At some point the procedure changed the dimensions of the capture from 1920x1080 to 1680x1050. So the calibration was done incorrectly.

    PS: The error in aruco_calibration.exe (in Debug) is:

    aruco_calibration.exe live:1 salida.yml -size 0.03711
