15 ??? Recap.
  • 8 - 16 September
  • 9-12 - 22-23 and 29-30 September
  • 13-14 - 6-7 October - staff seminar - possibly self-managed work only

Chapter 5. Projective Reconstruction (two weeks ?)

This plan is tentative and may be shortened as well as rearranged.

# Topic Reading Keywords
17 Relative Pose Ma 2004:Ch 5.1 Triangulation. Relative Pose. Essential Matrix.
18 Eight-point algorithm Ma 2004:Ch 5.2 Calculate Essential Matrix
19 Study Technique Ma 2004:Ch 5.1 Proof reading.
20 Synthetic Experiment Ma 2004:Ch 5.1-2
21 Planar Scenes Ma 2004:Ch 5.3
22 Epipolar Geometry Ma 2004:Ch 5.1-3

Notes from last year

  1. Synthetic Experiment should be merged into Eight-point algorithm
  2. Study Technique should probably be done earlier in the semester
  3. 3D modelling took a lot of time. Many did not realise that they needed to find triangles. Rectangles mixed with triangles caused problems.
  4. Generally, the preliminary steps of the exploratory exercises should have been premade, to save time for the students.
  5. Algorithm implementation is difficult and require sample solutions

New. Machine Learning

TBC

Chapter 6 and 11. Projective Reconstruction (many weeks)

This will be shortened and probably based on different sources.

# Topic Reading Keywords
23 Distorted Space Ma 2004:Ch 6.1-2
24 Stratified Reconstruction Ma 2005:Ch 6.3-4
25 Partial Scene Information Ma 2005:Ch 6.5
26 Real World Reconstruction Ma 2004:Ch 11

Notes from last year

  1. We can skip Stratified Reconstruction and Partial Scene Information
  2. Distorted Space may be interesting as an introduction to inner product spaces.
  3. What can we make out of Real World Reconstruction?
