of the image photographed by the web camera is insufficient and cannot be recognized.
Please pay attention to the points described below and make adjustments of the photographic image using the
camera setup screen or the utility of the web camera, then try the calibration.
• Set up and adjust the camera so that the background of the screen (e.g., walls, etc.) does not enter the photographic range of
