  1. 11. Data-driven methods for estimation of dynamic OD matrices

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Author : Ina Eriksson; Lina Fredriksson; [2021]
    Keywords : Large-scale mobility data; Dynamic OD matrix; Unsupervised learning; Sensor fusion; Kalman filter; Principal component analysis; Online estimation; OD estimation;

    Abstract : The idea behind this report is based on the fact that it is not only the number of users in the traffic network that is increasing, the number of connected devices such as probe vehicles and mobile sources has increased dramatically in the last decade. These connected devices provide large-scale mobility data and new opportunities to analyze the current traffic situation as they traverse through the network and continuously send out different types of information like Global Positioning System (GPS) data and Mobile Network Data (MND).

  3. 12. Smartphone Based Indoor Positioning Using Wi-Fi Round Trip Time and IMU Sensors

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Gustav Aaro; [2020]
    Keywords : Wi-Fi RTT; Indoor positioning; FTM; Android; Smartphone; Sensor fusion; IPS;

    Abstract : While GPS long has been an industry standard for localization of an entity or person anywhere in the world, it loses much of its accuracy and value when used indoors. To enable services such as indoor navigation, other methods must be used. A new standard of the Wi-Fi protocol, IEEE 802. READ MORE

  4. 13. Robot Localization with Radio Frequency Identification and Time Difference of Arrival

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Håkan Göransson; [2020]
    Keywords : ;

    Abstract : In today’s robot technology it is important to have a system that enables fora robot to find its own position. This can be achieved with different kinds ofsensors, such as LIDAR, GPS and cameras, and sensor fusion. READ MORE

  5. 14. The Effects of Sensor Fusion on Localisation in a Sparse, Outdoor Environment

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Kayla Kearns; [2020]
    Keywords : ;

    Abstract : This thesis compares the results of a localisation algorithm for a mobile robot in both a sparse and a densely featured environment whilst varying key parameters. The software and hardware required to enable the mobile robot to localise itself in the sparsely featured, GPS-denied, outdoor environment is described. READ MORE

  6. 15. GPS-oscillation-robust Localization and Visionaided Odometry Estimation

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : HONGYI CHEN; [2019]
    Keywords : Adaptive Extended Kalman Filter; Localization; Stereo visual odometry; GPS outage; Adaptivt förlängt Kalmanfilter; lokalisering; stereovisuell odometri; GPS avbrott;

    Abstract : GPS/IMU integrated systems are commonly used for vehicle navigation. The algorithm for this coupled system is normally based on Kalman filter. However, oscillated GPS measurements in the urban environment can lead to localization divergence easily. READ MORE
