how the mirrors are mounted on the axis of the mirror motor. Negative values
are to the left/up, positive to the right/down, from the system point of view.
3.
Press the “Start Scan” button and wait for the application to build an image of
the defined area. While the image is being built, a counter will indicate how
many scans there are left until completion.
4. You can choose to show the scanned image in a multi-colour scale (when
“Distance” is selected) and the in a blue-white gradient scale (when
“Amplitude” is selected), see figures below.

5.
Next, use the paint tool (“Paint” button) to mask/hide those areas in the image
that should not be considered as the ground. Use left-click to mask and right-
click to erase the mask.
6. When all non-
ground areas have been masked, press the button “Use
Calibra
tion”. A dialog will be displayed, asking for confirmation.
7. Verify that the point-graph (with a white background) in the lower part of the
window accurately represents the silhouette of the area in the middle of the
newly masked image. In most cases, the points should form a straight line.
4.4.2 Alternate Calibration Procedure
If conditions are such that they prevent the system from obtaining a good image of the
apron, an alternate method for calibration can be used. The procedure is as follows:
1.
Check the “Reduced mode” checkbox on the right side (this disables the
Paint-option).
2. Press and hold Ctrl and left-click along the centreline (use reflexes while
scanning the image if it is not visible). For each click, a new marker will be
placed. Two markers are sufficient in most cases but if there are slopes or
rises in the apron you should place one marker on each top/bottom.
a. When the first marker is placed, a second marker in a different colour is
placed to the right. This marker shall be moved to the side as far away as
possible from the centre of the image, while still being placed on an area
where there is ground and within the inner and outermost marker. Again,
use reflexes if needed.
