    Hi there,

    I know that v3.0 has been there since some times, but since then, I can’t create objects with my own photos.

    I tried with the one from your tutorial, and it’s working fine, but when it try with some photos from old projects, that’s not working.

    I have a Canon EOS-1D Mark IV and Online Calibration doesn’t catch anything (even with the tutorial’s photo) ==> No Online calibration data available.

    I try to operate with my antivirus/firewall off, but it doesn’t work ever (AVG, for the antivirus/firewall).

    Always the same error message (with one, is from a test with 25 photos, urban and default preset) :
    Aborting Samantha: Too few images

    Can you help me ?

    Hi Eros,

    zephyr is completetly autocalibrated, which means that if the camera pre-calibration is available, zephyr will speed up the computation. Only some cameras (mostly those with very unusual distortion) really require it. It’s correct, the cherb dataset does not have a camera calibration.

    Have you tried other settings, such as Urban/Deep ?

    Hi Andrea,

    Thank you for your answer.
    I just tried with Urban/deep and Urban/Exhaustive and that don’t work.
    Same error message.
    FYI, I tried with 2 different PC for the same result.
    Can i send you my photos to test it ?

    Hi Christophe,

    thank you for sharing the dataset.

    I did some testing. I can correctly orient all 25 cameras, both as close range/default and urban/default, and happily extract a 3D model.

    It’s likely that you changed some advanced settings (in custom mode) that didn’t revert back. Could you please try to reset zephyr to factory settings and try again? (options -> application tab)

    Andrea
