as sharp as possible. Set up the focus is by scrolling a wheel next to the projector lens.
As the cameras are not focused yet, the image may be blurred. Evaluate the
adjusted sharpness visually by the calibration plate.
Install the plate in such a way as to ensure that the blue markings on the view from
one of the cameras has matched with furthest marks on the calibration plate, as shown
in the figure below. When placing plate on the stand, pay attention that top part of the
plate has black triangles. Move the plate closer to or further away from the scanner,
until the image from the camera will not display that the vertical lines of grid cross the
furthest marks on the plate. On the figure the working distance is determined by the
right-hand camera. The distance from the scanner cameras to the plate shall be
maintained in this position during calibration and scanning (hereinafter - working
distance).
