Re-projection error reported by calibrateCamera, but Calibration Succeded!

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?

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!
