Why is a pin-hole camera rarely used in practice?
Exposure times are long
In a camera, the incoming light is focussed onto:
the back focal plane
Which of the following is not an assumption we have made in considering computational stereo?
The object is stationary
As the baseline, the distance between the cameras, increases, what happens to the disparity?
The disparity increases
Which of the following is usually the most important source of error in computational stereo?
Failing to align the optical axes to be parallel
In order to use computational stereo, we must find:
The location of the same feature in the left and right images
The disparity of a nearby object is:
greater than that of a distant object
What is disparity?
The discrepancy in the apparent position of an object in the left and right images
How does disparity vary with distance?
Disparity is inversely proportional to distance
Which of the following equations determines the distance to an object $Z$ given its disparity $D$, baseline $B$ and focal length $f$?
$Z = fB / D$
