  1. 1. Map change detection using GPS position data

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Lina Sjöstrand; Fanny Andersson; [2018]
    Nyckelord :autonomous driving; change detection; map inference; GPS; road network; HMM; Viterbi algorithm; OSM; map matching; crowd-sourced data; update maps; Technology and Engineering;

    Sammanfattning : Technology advancement in autonomous driving is accelerating. For the technology to be safe it is crucial for the vehicles to have an updated map, meaning all vehicles should have a correct and identical representation of the current road network. LÄS MER

  3. 2. One Shot Object Detection : For Tracking Purposes

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Tijmen Verhulsdonck; [2017]
    Nyckelord :Object tracking; Deep learning; Siamese neural network; Affine regression network; One shot learning; Object detector; PID controller;

    Sammanfattning : One of the things augmented reality depends on is object tracking, which is a problem classically found in cinematography and security. However, the algorithms designed for the classical application are often too expensive computationally or too complex to run on simpler mobile hardware. LÄS MER

  4. 3. Computer-assisted fracture reduction in an orthopaedic pre-operative planning workflow

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

    Författare :Ludvig Mangs; [2017]
    Nyckelord :3D puzzle solving; geometric matching; orthopaedics; fracture reduction;

    Sammanfattning : This report presents three implementations for solving 3D puzzles of fractured bones: two semi-automatic ones and one which is automatic. These are compared using qualitative as well as quantitative tests to find out if less interaction can yield equal or better results. Qualitative tests are performed on real clinical data from CT-scans. LÄS MER

  5. 4. Performance of map matching and route tracking depending on the quality of the GPS data

    Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Författare :Prokop Houda; [2016]
    Nyckelord :Map matching; Route tracking; GPS; Error; Sampling; Density;

    Sammanfattning : Satellite positioning measurements are never perfectly unbiased. Due to multiple types of errors affecting the signal transmission through an open space and urban areas each positioning measurement contains certain degree of uncertainty. LÄS MER

  7. 5. Development of an automated matching algorithm to assess the quality of the OpenStreetMap road network : a case study in Göteborg, Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Julian Will; [2014]
    Nyckelord :OpenStreetMap; automated matching; quality assessment; volunteered geographic data; linear features; Physical Geography and Ecosystem analysis; Earth and Environmental Sciences;

    Sammanfattning : In the last decade a new and alternative source of geospatial data has become available, so called Volunteered Geographic Information (VGI). Private individuals voluntarily collect large amount of geographic data for a joint project. This data are usually free under certain licence restrictions. LÄS MER
