Fall 2018 - Vision Algorithms for Mobile Robotics

UZH-BMINF020 / ETH-151-0632-00L



The course is open to all the students of the University of Zurich and ETH. Students should register through their own institutions.



Goal of the Course


For a robot to be autonomous, it has to perceive and understand the world around it. This course introduces you to the key computer vision algorithms used in mobile robotics, such as feature extraction, multiple view geometry, dense reconstruction, tracking, image retrieval, event-based vision, and visual-inertial odometry (the algorithms behind Apple ARKit, Google ARCore, Microsoft Hololens, Magic Leap and the Mars rovers). Basics knowledge of algebra, geomertry, and matrix calculus are required.



Time and location


Lectures: every Thursday from 10:15 to 12:00 in ETH LFW C5, Universitätstrasse 2, 8092 Zurich.

Exercises: Thursdays, roughly every two weeks, from 13:15 to 15:00 in ETH HG E 1.1, Rämistrasse 101, 8092 Zurich.

Please check out the course agenda below for the exact schedule.

Exercises


You will be required to bring your own laptop to the exercise session. You will need to have Matlab already pre-installed in your machine for the exercise.

  • UZH students: Download from here; Info on how to setup the license can be found there.
Please install all the toolboxes included in the license.



Grading and optional Mini Project


The final grade is based on the oral exam (30 minutes, exam date for UZH: Jan. 10, 2019; exam date for ETH students will be between January 7 and 29, 2019 (the effective ETH dates will be communicated by ETH before Christmas). Mini projects are optional. Depending on the result of the mini project (the Project Specifications will be communicated on this page later during the course), the student will be rewarded with a grade increase of up to 0.5 of the final grade. However, notice that the mini project can be quite time consuming. Mini project specifications and files can be found in the table below. The deadline for the mini-project is Sunday, 06.01.2019, 23:59:59, and it can be submitted via e-mail to the assistants (detailed instructions in Project Specifications, to appear).

Oral Exam Questions (udpated 21.12.2017)


The oral exam will last 30 minutes and will consist of one application question followed by two theoretical questions. This document contains a "non exhaustive" list of possible application questions and an "exhaustive" list of all the topics that you should learn about the course, which will be subject of discussion in the theoretical part.




Spring 2015 - Autonomous Mobile Robots


The course is currently open to all the students of the University of Zurich and ETH (Bachelor's and Master's). Lectures take place every Monday (from 16.02.2014 to 30.05.2014) from 14:15 to 16:00 in the ETH main building (HG) in room E 1.2.
