TSRT14 Sensor fusion
Course Information VT2, 2021
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 nonlinear 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 nonlinear filters (extended Kalman filter, unscented Kalman filter, particle filter) to nonlinear 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 comprise:
Exercise sessions: 8
Laboratory exercises: 2link.
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".
To activate the toolbox, run the included command
initSigSysin matlab. To use the latest version of the toolbox in the Linux computer labs, run:
module add courses/TSRT14in a terminal prior to opening matlab, or install a current version of the toolbox in your home directory as you would at home.
