    Hello again.

    So I've been trying to calibrate the cameras on a VOXL Flightcore and everytime the calibration is finished, a max reprojection error happens. I am not sure what this is caused by.

    Is it due to the camera quality? It's strange because it has happening on both of the drones I'm working with.

      We managed to get it to work once after changing the lighting in the room, but we cannot get the intrinsics file to generate for some reason

        We managed to fix the intrinsic file not generating by deleting the already existing extrinsic file

          Hi, you managed to succeed for all calibration? If so, how did you do that?

            I had the same issues but even with different lighting, I cannot get it to work. I managed to calibrate the tracking camera but not the stereo. Does anyone have any idea how I could try to fix this?

            I have the same problem: The reprojection error is to large for the stereo cameras and the calibration fails.
