Camera Calibration Instructions

1. Create a folder named calib_photos inside the camera_calibration folder.
2. Print without any border adaptation, in an A4 paper sheet, the chessboard in the pattern.png file.
3. Attach the chessboard paper sheet to a planar/flat rigid surface, like a thick carboard piece or a clipboard.
4. With the desired camera/webcam, shoot various photos (20+) of the chessboard, with various angles.
5. Transfer all the photos to the calib_photos folder.
6. Ensure the cameracalib.py script has the correct path for the calib_photos folder.
7. The valid chessboard photos are visualized, after skipping them pressing a button, the camera coefficients are computed and printed out (may require some time).
8. Copy the camera parameters and save them to a file for late usage.
