Lens calibration by moving camera?

asked 2017-05-11 13:53:23 -0600

I have a camera on a machine looking at a flat surface. Would it be possible to correct the fisheye lens effects by moving the camera and then using optical flow?

It may be easier to use the checkerboard pattern but was just wondering if this was possible.

Thanks Trampas

It is possible, but not built into OpenCV. You don't need to use the checkerboard pattern though. Any points you can measure on the surface of the table will work, and you can track those with optical flow.
