It was at this point that the operator must allow the software to find the reference point (0.0) of the electronic card by pressing "setting reference point ',There are two solutions currently implemented or commented in the code: the first was to light a LED controlled by an Arduino UNO, then take the position.The second is a simple manual calibration by clicking on the edge of the electronic card corressponding at (0,0) or the top corner left pictures taken (if you place the card in the direction of reading ahead on the bench, which leads the captured by the webcam image is to be an image in reverse of the card).
Then the reference point to set the conversion values Pixels to mm with the "configuration of the scale units of pixels / mm" option, he lightsled a second then takes the coordinates of the spot (possible accuracy with small LED (0.3)) or this it just necessary to pressing "setting reference point", and clicking on the edge of the electronic card at the opposite. then exit feature that closes the video stream.
