6 FIELD OF VIEW CALULATION
The iQ-
FoV Box offers a simple way to check a camera’s angle of view (horizontally/vertically). The iQ-
FoV Box is supplied with four magnetic rulers that should be placed as shown in Image 03.
Image 03: horizontal/vertical distances and camera centering
Image 04: camera distance, origin of measure
Use distances a
1/2
, b
1/2,
and d in the following formula to calculate the angle of view:
for horizontal angle
for vertical angle
d is the distance the camera moved into the iQ-FoV Box measured from the front plate (see the left side
of Image 04). The measure's origin is shown in Image 04 on the right side and is located in the center
of the front plate.
Please note that it is essential to center the camera for field-of-view calculations. The lens's
optical axis has to be orthogonal to the backplane and centered around 510 mm in height
and width of the iQ-FoV Box.
