Be careful when selecting the plate, specifying its size, and during calibration! When
the calibration is incorrect, there may be problems when scanning and you will receive
model with distorted size.
Specify the added plate in the list
Select plate
. When making a selection, settings of
Lenses will automatically be changed. RаngeVisiоn Smart always has focal length of
the lenses of 4.3 mm.
Calibration is performed without illumination with natural light, when you start the
calibration dialogue, the mode
"Black light"
is activated. Using the slider in the toolbar
increase the value of exposure of the cameras. If the image of the plate is still dark,
increase the brightness of the external lighting.
After this, click
Capture
. Camera will focus on the calibration plate. Visually inspect
the sharpness of the cameras after focusing.
If the cameras are focused, you will get a snapshot of the plate in the first position.
At the calibration during shooting both the scanner and the calibration plate must be
fixed relative to each other! To make snapshots in other positions, set the plate
according to the instructions in the program and a schematic representation. Do not
change the distance to calibration field, if this is not stated in the prompt (positions 10
and 11). To set the plate to the desired position, change the position and tilt of
magnetic stand, or the position of the scanner on a tripod.
After the last snapshot will be performed an analysis of the data for calibration.
