# Assessment Guide (Machine Vision)

**DRAFT UNDER CONSTRUCTION**

A final version of this exam will be published before the teaching term ends.

# Overview

- The exam is viva voce.
**Duration**Normally 20 min. May extend up to a maximum of 30 min.- The student manages the first seven minutes of the exam to make their case to demonstrate that the learning outcomes have been achieved.
- The student is free to bring any material desired to serve as a demonstration. However,
- having developed a product is not sufficient.
- The candidate has to demonstrate that they understand how to develop the product. See below for elaboration.
- This is both because depth understanding is a learning objective in itself, and because we cannot otherwise know if the student has developed the demo themselves.

- The remaining 2/3 of the exam is for further questions from the examiners to make sure that all the learning outcomes are covered.

# Learning outcomes

The assessment is made with respect to the learning outcomes from the Module Description, as follows (with numbering added).

**K1** The candidate can explain fundamental mathematical models for digital imaging, 3D models, and machine vision

**K2** The candidate are aware of the principles of digital cameras and image capture

**S1** The candidate can implemented selected techniques for object recognition and tracking

**S2** The candidate can calibrate cameras for use in machine vision systems

**C1** The candidate has a good analytic understadning of machine vision and of the collaboration between machine vision and other systems in robotics

**C2** The candidate can exploit the connection between theory and application for presenting and discussing engineering problems and solutions

# Interpretation of Grades and Learning Outcomes

## The Grade C

The Grade **C** represents solid working knowledge of the most important techniques in the syllabus. This includes

- Sufficient knowledge to be able to implement and use the technique. (S1)
- Sufficient theoretical understanding to vary the techniques and adapt them to different use cases, including but not limited to parameter tuning. (C2)
- Sufficient theoretical understanding to explain when and why the technique is appropriate. (K1, C1)

Which techniques are most important may be subject to opinion, but the following has a good case,

- Feature tracking - i.e. identification of objects in a video, and tracking of these objects across several frames.
- Calculation of relative pose, triangulation, and 3D reconstruction.
**TODO**The wording needs review.

A student who merits a C can be trusted to implement these techniques correctly in a project without close supervision.

Students who have focused on other techniques which are important for their own education, may choose to focus on them, as long as

- they are taken from the syllabus, possibly extended with other sources.
- they constitute a similar volume and challenge as the above.
- they address the learning outcomes (S1, C2, K1, C2) as mentioned above.

The student also needs a cursory understanding of the remaining learning outcomes (K2, S2).

We respect that some students may have a more practical, and others a more theoretical understanding of the technology, and that both may merit the same grade. The **C** Grade is a broad category.

## The Grade A (and B)

The Grade **A** represent broad and deep understanding of all the material discussed in the module. This includes the requirements for a **C**, and additionally the **A** student has

- working knowledge of additional techniques from the syllabus.
- solid understanding of learning outcome K2 and S2.
- deeper and more complete understanding of the underlying theory than we expect for a
**C**

To merit an **A** the candidate has to impress and surprise. The performance has to *clearly outstanding*, as it says in the nationaly guidelines:

An excellent performance, clearly outstanding. The candidate demonstrates excellent judgement and a very high degree of independent thinking.

The Grade **B** is an intermediate grade. The candidate demonstrates some features of an **A** and thus exceed the expectations for a **C**, but they do not have to be `clearly outstanding’.

## The Grade E (and D)

Grades below **C** represents working knowledge which can possibly be of value in a development team, but not sufficient for the candidate to be trusted to carry out independent work.

As for the **C**, the candidate has to

- demonstrate working knowledge of the most important techniques in the syllabus,
- be aware of most of features that require tuning and adaptation in practical situation.

Unlike the **C**, a certain awareness of the underlying theory suffices. This is not expected to suffice to adapt and justify solutions to practical uses beyond routine problems.
