Step 13Adjust focus and light
Adjust the camera focus and the light in the room so that the four calibration markers at the corners of the board are recognized and highlighted.
It is best if they are stable, but it can be ok if they blink a little.
If you see a large rectangle in the centre of the image, this means that the application does not see anything :-( please try to adjust light and focus until the rectangle disappears.
Place some blocks on the board and check that they are recognized and highlighted, if not try adjusting the focus and light again. It is best if they are stable, but it can be ok if they blink a little.
