WebIn addition, call the distance between the camera and the two points L. The camera's field of view ( F O V) (or angle of view as is more common in photography) can be calculated by. F O V = 2 arctan ( d 2 F) which, for a scene at distance L corresponds to a scene dimension W equal to. W = 2 ⋅ L ⋅ tan ( F O V / 2) = L d F. WebParallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight and is measured by the angle or half-angle of inclination between those two lines.
