Calibration Pattern Size Please choose the width and height (number of inside corners) of the checker board pattern you will be using for calibration. Default is 6 by 8 corners. You may find a checkerboard pattern at http://opencv.willowgarage.com/pattern http://opencv.willowgarage.com/pattern Camera Settings Change the camera settings. Be aware that BW is much faster for previewing, than color. Also, if you change the image size, you should rerun calibration. Default values: BW and 640x480 are a good start. Calibration calculations have started... Calibration calculations has stopped. Calibration finished, you camera is calibrated. Calibration Please capture atleast 10 images of the pattern!
