Institutionen för systemteknik Department of Electrical Engineering Examensarbete Localization algorithms for indoor UAVs

The increased market for navigation, localization and mapping system has encouraged the research to dig deeper into these new and challenging areas. The remarkable development of computer softand hardware have also opened up many new doors. Things which more or less where impossible ten years ago are now reality. The possibilities of using a mathematical approach to compensate for the need of e...

Institutionen för systemteknik Department of Electrical Engineering Examensarbete Autonomous Mapping and Exploration of Dynamic Indoor Environments

This thesis describes all the necessary parts needed to build a complete system for autonomous indoor mapping in 3D. The robotic platform used is a two-wheeled Segway, operating in a planar environment. This, together with wheel odometers, an Inertial Measurement Unit (IMU), two Microsoft Kinects and a laptop comprise the backbone of the system, which can be divided into three parts: • The loca...

Institutionen för systemteknik Department of Electrical Engineering Examensarbete Performance Enhancement of Bearing Navigation to Known Radio Beacons

This master thesis investigates the performance of a car navigation system using lateral accelerometers, yaw rate and bearings relative three known radio beacons. Accelerometer, gyroscope and position data has been collected by an imu combined with a gps receiver, where the imu was installed in the approximate motion center of a car. The bearing measurements are simulated using gps data and the...

Institutionen för systemteknik Department of Electrical Engineering Examensarbete Target Tracking

Starting from Maxwell’s equations, we derive a sensor model for three-axis magnetometers suitable for localization and tracking applications. The model depends on the relative position between the sensor and the target, orientation of the target and its magnetic signature. Both point targets and extended target models are provided. The models are validated on data taken from various road vehicl...
