7.8 Camera calibration
7.7.3 Conguring the 3rd to 8th measured values:
 Proceed as for conguring the 2nd measured value for all fur-
ther measured values that are to be output.
First enter the camera CAN address, then set one sub ad-
dress (parameters 48 to 53) and initiate a reset. Finally, set
the operating mode of the new measured value.
7.7.4 Deactivating the output of measured values:
➜Callupsetupeditor
➜Enterthecameradevicenumberinparameter0.
1 for the camera
➜Enterthecameragroupnumberinparameter1.
0 for the camera
➜Setthesubaddress(parameters47to53)ofthemeasuredvalue
thatistobedeactivatedto00.
0.0 in parameter 47 for the second measured value
➜Entera1(reset)inparameter3,thenchangeparameterstoiniti-
atethereset.
Toachieveauniformreferencevariableforcontrolormeasuring
systemsignals,allsensorsandactuatorsmustbecalibratedinrela-
tiontothisuniformreferencevariable.
 Therearetwodifferentcalibrationproceduresforthecamera,
standardcalibrationandtemplatecalibration.Thelatterisintend-
edforcamerasimplementedinlaminationprocesses.
7.8.1 Standard calibration
Forcameracalibrationatemplateisrequiredthatisinsertedinthe
camerameasuringrangeinsteadoftheweb.Seeillustrationoppo-
site.
 The template must lie within the measuring range set in the
rst measuring value (see camera conguration). It must
be positioned on the same plane as the web will run subse-
quently. It should cover as large an area of the measuring
range as possible, approx. 2/3 of the web width.
Thecameraresolutioncanbecalculatedfromthewidthofthetem-
plateandthedistancemeasured:
