Alignment with LRF unit as reference
Step Action
1 Press the TV/IR button to select the camera that has the best visibility for the present
conditions.
2 Use the joystick to direct the system towards the alignment object.
3 Use the optical zoom and zoom in maximally, see section 11.2. (Do not use the digital
zoom.)
4 Use the joystick to direct the system outside the alignment object.
5 Use the LRF unit to measure the distance to the object, see section 11.5.
6 By estimating the distance to the object and comparing with the LRF result, it should be
possible to determine if it was a hit or a miss.
7 a If it was a hit, move the system a little bit more away from the object. Return to step 5.
7 b If it was a miss, move the system a little bit towards the vertical edge of the object and
measure the distance again. Repeat until a hit is registered.
8 The edge of the laser lobe should now be at the vertical edge of the alignment object and
in best case the crosshair reticle is in the middle of the laser lobe, as shown in the right
part of Figure 9.9.
9 Use the joystick to direct the system to the other side of the alignment object, see gure
9.10.
10 Measure the distance again and move the system a little bit towards the vertical edge of
the object until a hit is registered.
11 In best case, the crosshair reticle is now at the same distance from the vertical edge of
the distant object as in step 8. In that case, the azimuth alignment of the camera is correct
and no azimuth adjustments shall be made.
12 If the azimuth alignment is not correct, as in Figure 9.11, adjust the position of the camera
according to the azimuth adjustment procedure in section 9.3.4.1.
Repeated distance measurements and azimuth adjustments may be needed before the
azimuth alignment is correct.
13 Use the joystick to direct the system above the alignment object.
14 Measure the distance again and move the system a little bit towards the horizontal edge of
the object until a hit is registered.
15 In best case, the crosshair reticle is now at the same distance from the horizontal edge as
it was from the vertical edge. In that case, the elevation alignment of the camera is correct
and no elevation adjustments shall be made.
