How it works
The vertical field of view comes from the horizontal one and the image shape. The bottom edge of the image looks down at the tilt plus half the vertical view, so it meets the ground at the height divided by the tangent of that angle: that distance is the blind spot. The top edge looks down at the tilt minus half the vertical view; if that angle is zero or less, the image reaches the horizon. The same sums at head height show where people come into view.
