Dual camera system
Fig.26: Dimensioning the measuring range for a dual camera system
M = Measuring range
D
= Measuring distance
(distance material web - end of lens barrel)
D
1
= Distance material web – sensor level (D + 138 mm)
J = Maximum incoming web position error (to one side)
AB
max
= Maximum working width (maximum material width)
AB
min
= Minimum working width (minimum material width)
Determining the camera measuring range M:
M = ((AB
max
– AB
min
) / 2 + 2 x J) x 1,1
