1. If the nearest distance to be measured is 16 meters, what is the largest disparity that will occur (in pixels)?

2. What is the distance resolution at 16 meters, due to the pixel spacing?

3. What distance corresponds to a disparity of one pixel?

A stereoscopic system is being contemplated for terrain mapping. It will
consist of two CCD cameras, each having ${512}\times {512}$ pixels on a
10 cm $\times$ 10 cm square sensor. The lenses to be used have a focal
length of 16 cm, with the focus fixed at infinity. For corresponding
points ($u_1,v_1$) in the left image and ($u_2,v_2$) in the right image,
$v_1=v_2$ because the $x$-axes in the two image planes are parallel to
the epipolar linesâ€”the lines from the object to the camera. The optical
axes of the two cameras are parallel. The baseline between the cameras
is 1 meter.
