**Note** The lecture plan as posted at the start of semester is last
year's schedule.  There will not be any revolutionary changes, but
it will be reviewed and amended as we go along.

# Chapter 1-3. Introduction; 3D geometry and projections

**Dates** 21, 24, 28, and 31 August, and 4 and 7 September

| 1 | [Introduction]()         | Ma 2004:Ch 1 (Ch 2.1 and 2.3) | Practical matters. Software installation. Recap of linear algebra. | OK |
| 2 | [3D Modelling]()         | Ma 2004:Ch 2, App A (SZ 2)   | 3D modelling, motion | OK |
| 3 | [3D Objects in Python]() | Tutorials                    | Homogeneous co-ordinates.  General Rotations. 3D Transformations in Python | OK |
| 4 | [Image Formation]()    | Ma 2004:Ch 3-3.3.1 (SZ 6) | (self-study) projection, lens/camera | |
| 5 | [Camera Calibration]() | Ma 2004:Ch 3.3-3.3.3 | (self-study) Calibration, Radial Distortion etc. |
| 6 | [Three-week Recap]()   | Ma 2004:Ch 1-3 | 3D Motion and 2D Projections |  To be adapted to class need|
| 7 | Recap: [Camera Calibration]() | Ma 2004:Ch 3 | | Many students needed more time to get the calibration to work.  |

**Note** It could have been useful to do a session on Theorem 2.8, training proof
reading skills.

# Chapter 4. Feature Tracking

We need to interleave this with material from later blocks to have
project tracker run over midterm.
[Study Technique]() may be a good candidate.
