Camera calibration instructions:
1. After the live view has started, place the calibration board so it is
   completely visible within the camera frame and is stationary
   - The board should be placed at the desired scanning distance
2. Adjust the camera's aperture and focus until the image is well
   illuminated and sharp
   - Lock the aperture and focus in place if possible
   - If the camera focus or aperture is adjusted, the calibration must be redone
3. Select the live view window and press the SPACE_BAR key to capture
   the calibration board's current position
4. Move the calibration board and repeat step 3 until calibration is complete
   - Capture images with the board at different distances from the camera
   - Capture images with the board at different positions in the camera frame
   - The position of the camera can be changed as well rather than moving the
     board

NOTE: Press ESC key to quit the calibration routine
