    I calibrated the tarcking camera, and calibration was successful, but I got e-projection error reported by calibrateCamera.
    What is the problem?
    How can I solve it?

    Drone: RB5
    hw version: M0052
    voxl-suite: 1.1.2
    PX4 Version: 1.14.0dev

      There will always be some reprojection error when computing a homography, as long as the error is below 0.5 (which it looks like yours is) you should be totally fine.

      Let me know if you have any other questions!
