Course Description

Vision-based localization, mapping, and navigation have recently seen tremendous progress in computer vision and robotics research. Such methods already have a strong impact on applications in fields such as robotics and augmented reality.

In this course, students will develop and implement algorithms for visual navigation and 3D-reconstruction, relevant for applications such as autonomous navigation of wheeled robots and quadrocopters, tracking of handheld devices, or 3D reconstruction. The investigated algorithms may include, visual odometry, structure from motion, simultaneous localization and mapping with monocular, stereo, or RGB-D cameras, (semi-)dense 3D reconstruction.

Number of participants: max. 12

Course Layout
  • Lecture & Exercise : up to 2 hours per week recorded video lecture; 2 hours per week tutored Q&A and exercise session, Mondays from 4pm to 6pm. There are 5 lecture & exercise sessions. Each week, the exercise for the following week will be announced and has to be handed in online by each student individually within 2 weeks. Attendance to lecture and tutor sessions are voluntary but highly encouraged.
  • Project : After the initial 5 weeks, students should form groups of 1-2. Each group will be assigned to a project. Students can work on their own and consult the tutors in a weekly meeting to discuss project progress and next steps. Attendance to meetings with tutors is mandatory.
  • Presentation and demo : Each group will be assigned a time slot on one of the last days of the semester to present their results, followed by a Q&A session. The presentation shall be 12 minutes long + 3 minutes for questions. The presentation should comprise 5-10 slides to explain the project goals and results to fellow students and may include a short live demo or video.
  • Project Report : Each group writes a report on their project work (10-12 pages, single column, single-spaced lines, 11pt font size; title page, table of content, and references will not be accounted for in the page numbers). The report should summarize the project goals, what was implemented, and what results were obtained.
Grading

The final grade will be determined by both the programming assignments and the project.

For grading the programming assignments we consider completeness and timely submission (not so many things such as code quality, as long as it works). Note that you have to complete all exercise sheets to pass the course, even if you miss a submission deadline.

In the project phase, the main focus is on your implementation, on the presentation and the report, but we will also consider how you approach the problem, how you engage with your tutors, and how you manage your time.

Tutor Sessions

We will start with general announcements, then do a common Q&A session for the latest lecture as well as the current and the previous exercise sheet. The usefulness for everyone depends on you asking questions.

Afterward, you are encouraged to work on the exercises. The call will remain open and you can talk to us about any issues that come up. While you can also work on the exercises in your own time, we encourage you to make use of the tutor sessions as much as possible, as most questions – that might hold you up otherwise – can usually be resolved quickly during the tutor session.

In case you cannot attend, you may also send us questions (on the latest lecture as well as the current and the previous exercise sheet) to visnav_ws2021@vision.in.tum.de and we will try to address them in the Q&A session. Please send us the questions at least one day in advance, if possible.

Projects

After the lecture and assignment phase is completed, students work in groups of 1-2 people on a more open-ended project. We will present some example projects, but you may also suggest your own.

See the projects slides (ss21) for more details.

Literature

A good introduction to many aspects of computer vision relevant for the practical project is the following course, which has recordings on YouTube:

The following book also covers many aspects. You should focus on Part II and III and selected background from Part I as needed:
