Hi heres my problem -
tan(α/2) = (l/2)/d, hence
α = 2*atan(l
with this formula I can calculate the horizontal field-of-view of my camera.
I found it at this site - Determining the viewing angle of your camera
Only I havent a scientific calculator or the where with all to solve this!
I need to find a - the angle of view.
I know that l is the width - 2290mm
and I know that d is the distance - 5000mm
Any help from your forum members would be great! please save me any more days trawling endless websites trying to make sense of this!
