#X text -65 -108 3 Check calibration toggle to start and move the chessboard
in front of the camera (or move the camera in front of your screen).
Your computer may slow down during searching chessboard corners. When
all corners are found it takes a snapshot (and the image will be negative)
;
#X text -65 -128 2 Plug a supported camera and start rendering;
#X text -64 -158 1 Print the chessboard ona rigid paperboard (or just
show it on the screen);
#X text -65 -37 4 When enought chessboard have been found (20 by default)
it computes transformation matrix and map to undistord the image;
#X text -65 13 5 Then all incoming images are undistord \, you can
save the transformation and distorsion matrix to files to load it next
times;
