R1 is radius of small circle, R2 is radius of large. The small circle is actually the base of a right cylinder and the big circle is the top. So in reality R1=R2. Given that R2=k*R1, k is some proportion, in the picture is there a way to determine the height of the cylinder?
I came to this question because originally I was thinking if there is a way to figure out the distance from observer A to B with a camera. You essentially move the camera upwards perpendicular to ground by x meter at the same time detecting by how much observer B moved (just like the cylinder question distance B moved is simply how it looks like on 2D).
Thanks ahead of time.
