Part III. Field-of-View with Math
Figure 1. The simple formula for Field of View (FOV)—the angle a person can see without moving
their eyes or their head.
You are now going to use your FOV measurements to calculate the FOV more precisely.
If x marks your FOV (either in horizontal or vertical direction), the FOV can be calculated as
FO
V =
x (“how high you can see”)
d (“how far you measured”)
This measures the FOV in units called radians. To convert to angular degrees, multiply this number by
180 ˚/π , where π = 3.14. That is,
F
