It may not be programming related, but perhaps programmers will be in a better position to answer it.
To calibrate the camera, I have an 8 x 8 square sample printed on a piece of paper. I need to manually enter these coordinates into a text file. The software then selects it from there and calculates the calibration parameters.
Is there a script or some software that I can run on these images and get the pixel coordinates from the four corners of each of the 64 squares?
