1. In Figure 1 on the last page there are three cameras where the distance between the cameras is B, and all three cameras have the same focal length f. The disparity dL-x0 - xL, while the disparity dR XR-x0. Show that ldL.-dR. You should prove this relationship holds mathematically by using the appropriate equations. This proof is trivial, but when you write the proof you should use an English sentence to explain why these particular equations are true. 2 marks
