9.3 Alignment
Alignment of the Ranger HRC MS system is performed by FLIR before
delivery of the system. There is no need to change the alignment during
normal operation or after normal disassembling and remounting of the
system.
However, after service or replacement of the IR Camera, TV camera and/
or LRF unit, a new alignment may be needed:
• If a camera has been replaced, its alignment with the rest of the sys
-
tem must be veried and adjusted if needed.
• If the LRF unit has been replaced, both the IR and TV cameras’ align
-
ment with the LRF unit must be veried and adjusted if needed.
9.3.1 Alignment method
The alignment method depends on the equipment that has been repla-
ced:
• If one camera is replaced, the other camera is used as reference.
• If both cameras are replaced and the system is not equipped with an
LRF unit, one of the cameras is used as reference.
• If both cameras are replaced, the LRF unit is used as reference.
• If the LRF unit is replaced, the LRF unit is used as reference.
If one of the cameras is used as reference, the reference camera is rst
directed towards a distant alignment object. The position of other camera
is then adjusted, so that it aims at the same alignment object. See section
9.3.2.
If the LRF unit is used as reference, range measurements are made closer
and closer to a distant alignment object to determine where the LRF unit
is aiming, see Figure 9.9. The camera is aligned to aim in the same way.
See section 9.3.3.
