  1. 1. Map Matching to road segments using Hidden Markov Model with GNSS, Odometer and Gyroscope

    University essay from Linköpings universitet/Programvara och system

    Author : Hugo Lindholm; [2019]
    Keywords : map matching; hmm; hidden markov model; gnss;

    Abstract : In this thesis the Hidden Markov Model (HMM) is used in the process of map matching to investigate the accuracy for road segment map matching. A few HMM algorithms using a Global Navigation Satellite System (GNSS) receiver, odometer and gyroscope sensors are presented. The HMM algorithms are evaluated on four accuracy metrics. READ MORE

  2. 2. Identification of absolute orientation using inertial measurement unit

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi; Högskolan i Halmstad/Akademin för informationsteknologi

    Author : André Kopfinger; Daniel Ahlsén; [2019]
    Keywords : Indoor navigation; absolute orientation; inertial measurement unit; IMU; indoor positioning;

    Abstract : Because of the limitation of GPS indoors there is a demand for alternative methods to accurately determine both position and orientation. Previous attempts at positional tracking has required an infrastructure of hardware and sensors to provide the path of an object or person. This is not a mobile solution to a mobile problem.

  3. 3. Six DOF tracking system based on smartphones internal sensors for standalone mobile VR

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

    Author : Fredd Duque; [2019]
    Keywords : Virtual reality; Positional tracking; Simultaneous location and mapping; Head-mounted-display;

    Abstract : Nowadays mid-range smartphones have enough computational power to run simultaneous location and mapping (SLAM) algorithms that, together with their onboard inertial sensors makes them capable of position and rotation tracking. Based on this, Google and Apple have released their own respective software development kits (SDKs) that allow smartphones to run augmented reality applications using six degrees of freedom tracking.

  4. 4. Pose AR: Assessing Pose Based Input in an AR Context

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Nilsson Jakub; [2019]
    Keywords : Augmented Reality; Natural User Interfaces; Mobile AR; Pose Estimation; relative distance and orientation input;

    Abstract : Despite the rapidly growing adoption of augmented reality (AR) applications, existing methods for interacting with AR content are rated poorly, with surveyors of the area calling for better means of interaction, while researchers strive to create more natural input methods, mainly focusing on gesture input. This thesis aims to contribute to the aforementioned efforts by recognizing that technologies for consumer-grade smartphone-based pose estimation have been rapidly improving in recent years and due to their increased accuracy may have untapped potential ready to be utilized for user input.

  5. 5. Generation and evaluation of collision geometry based on drawings

    University essay from

    Author : Bernhardsson Albin; Ivar Björling; [2018]
    Keywords : vectorization; image processing; segmentation; line simplification; vektorisering; bildbehandling; segmentering; linjeförenkling;

    Abstract : Background. Many video games allow for creative expression. Attractive Interactive AB is developing such a game, in which players draw their own levels using pen and paper. For such a game to work, collision geometry needs to be generated from photos of hand-drawn video game levels. READ MORE
