Assignment 3. Stereo and Motion ( Deadline:
Dec 03 midnight)
Note: All the writings must be in soft copies (PDF).
Please send the writing report to Prof. Zhu < email@example.com> as an
email attachment. You are responsible for the loss of your
submission if you don't include "Capstone 2018" (exactly) in the subject of your email.
1. (Stereo- 25 points ) Estimate the accuracy of the
simple stereo system (Figure 3 in the online
lecture notes of stereo vision) assuming that the only source
of noise is the localization of corresponding points in the two
images. Discuss the dependence of the error in depth estimation as a
function of disparity error, depth itself, the baseline width and
the focal length, respectively.
Hint: Z = fB/d; Take the partial derivatives of Z with respect to d,
B, f, respectively.
2. (Motion- 25 points) Could you obtain 3D information of a scene by
viewing the scene by a camera rotating around its optical
center? Show why or why not.
What about moving the camera along its optical axis?
3. (25 points) Discussion the similarities (at least 2 ) and
differences (at least 2) between stereo vision and visual motion .
4. (25 points) Give five examples where humans use stereo and
motion, and Google another five examples that use machine vision
algorithms of stereo and motion.
