checkerboard correction

[GOB]

Has anyone ever done a checkerboard calibration to the lens/camera in order to get more accurate position location?

Like this:
http://docs.opencv.org/2.4/doc/tutorials/calib3d/camera_calibration/camera_calibration.html

Would it be possible to do this once (either using OpenCV, Matlab, or another tool) and then apply some correction factor to the pixy output on an arduino?

Thanks!

Has anybody been able to successfully use this method to correct the fisheye effect on the pixy?

Thanks!
