The Piranha XL Camera

When both end of the line profile are equal to the center, then the camera will be aligned
both in the scan direction and rotationally with the black-to-white transition.
•
The accuracy of the adjustment can be increased by using 8 rows or even 4 rows. However,
this will be associated with an increase in sensitivity to camera adjustments. Start with 12
rows to get close and then move to 8 and then 4 rows. Ensure 4 and 8 rows are also Flat
Fielded to the same target as 12 rows.
