8.13.2 Inserting the Calibration Template
Before you start with the calibration, you have to insert the
calibration template into the field of vision of the CCD camera and
secure it in place (see figure).
Side view
The bottom side of the
calibration template is located
at the level of the
material bottom side
Fig.62: Correct alignment of the calibration template
① CCD camera ② Cover (impervious to light)
③ Light source ④ Material web
⑤ Calibration template
Observe the following points during the alignment of the calibration
template:
■ The bottom side of the calibration template ⑤ should (where
technically possible) be located at the level of the material
bottom side.
■ The angle α between the calibration template ⑤ and the view
axis of the CCD camera ① must be 90°.
■ The angle β between the calibration template ⑤ and the web
running direction must be 90°.
■ If the light source ③ is longer than the calibration template ⑤,
the area to the left of the of the first hole and the right of the
last hole of the template must be covered by a material ②
impervious to light.
