TSRT14 Sensor fusion
Course Information VT2, 2015
This page is currently being updated and subject to changes up until the course starts.
Goal:The student should after the course have the ability to describe the most important methods and algorithms for sensor fusion, and be able to apply these to sensor network, navigation and target tracking applications. More specifically, after the course the student should have the ability to
- Understand the fundamental principles in estimation and detection theory.
- Implement algorithms for parameter estimation in linear and non-linear models.
- Implement algorithms for detection and estimation of the position of a target in a sensor network.
- Apply the Kalman filter to linear state space models with a multitude of sensors.
- Apply non-linear filters (extended Kalman filter, unscented Kalman filter, particle filter) to non-linear or non-Gaussian state space models.
- Implement basic algorithms for simultaneous localization and mapping (SLAM).
- Describe and model the most common sensors used in sensor fusion applications.
- Implement the most common motion models in target tracking and navigation applications.
- Understand the interplay of the above in a few concrete real applications.
The course consists of
Laboratory exercises: 2
The lab contains one data collection part in our lab (RT3, Laboteket, which is located in house B, entrance 27, corridor C) and one data processing part where algorithms will be developed and applied to the data.
The participants will be examined with a lab report which will be peer-reviewed by other students attending the course. Each lab group will review one report each. The report is due on Sunday May 3, 2015, at 23:59, the review report is due on Friday May 8, 2015, at 23:59 and the resubmission of the lab report (if required) is due on Thursday May 28, 2015, at 23:59. The report may be written in English (preferred) or Swedish.
Lab reports: The each lab and review report should be submitted (as a PDF file) to the peer review system available here. The first version of the lab report should also be sent to Urkund (e-mail: manko86.liu_at_analys.urkund.se). Each group is also expected to create a reviewer account (one per each group) in the peer review system and review the assigned report. To make things more clear, you will create your reviewer accounts during the lab sesion under the supervision of a lab assistant. Keycode for the reviewer registration is tsrt14reviewer.
Orientation estimation using smartphone sensors. In this lab an orientation filter will be implemented using measurements from gyroscope, accelerometer and magnetometer in a smartphone. The lab is compatible with any android phone containing these sensors (which most modern smartphones do). The students can either use their own phones, or use a phone provided by the course. Matlab files are provided as well as the Sensor Fusion Android app which will be needed to stream sensor data from the phone to matlab.
The lab will consist of a 4 hour lab session in our computer rooms. The participants will be examined during the session and no written report will be required.
Office hours for the course are Mondays and Fridays 12:30-13:00. At these times the course assistant will be available to answer your course related questions week until May 30.
The course assistant is responsible for the lab schedule Manon Kok, manon.kok_at_liu.se, 013-284043.
Information during the course will be sent to the course mailing list. The list name, together with further information and sign-up, can be found on "Studentsidan".
