  1. 1. Map Based Sensor Fusion for Lane Boundary Estimation on ADAS

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Puya Faghi; [2023]
    Nyckelord :Lane estimation; Lane detection; Map-matching; Sensor fusion; Smart camera; Vehicle Radar; Intelligent vehicle systems; Körfältsestimering; Körfältsdetektering; Kartmatchning; Sensorfusion; Smart Kamera; Radar system; Fordonsradar; Intelligenta fordonssystem;

    Sammanfattning : A vehicles ability to detect and estimate its surroundings is important for ensuring the safety of the vehicle and passengers regardless of the level of vehicle autonomy. With an improved road and lane estimation, advanced driver-assistance systems will be able to provide earlier and more accurate warnings and actions to prevent a possible accident. LÄS MER

  3. 2. ESTIMATION OF POINT PROCESSES ON DIRECTED GRAPHS

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Virginia Jimenez Mohedano; [2022]
    Nyckelord :;

    Sammanfattning : Road accidents are one of the most important concerns worldwide. Studying and analysing them is one way to improve and ensure safety on the roads. Traffic accident records for four years have been provided and are analysed in this thesis. LÄS MER

  4. 3. Guardrail detection for landmark-based localization

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Nils Gumaelius; [2022]
    Nyckelord :computer vision; LiDAR; object detection; localization; landmark-based localization; guardrail detection; dbscan; autonomous driving;

    Sammanfattning : A requirement for safe autonomous driving is to have an accurate global localization of the ego vehicle. Methods based on Global Navigation Satellite System (GNSS) are the most common but are not precise enough in areas without good satellite signals. Instead, methods likelandmark-based localization (LBL) can be used. LÄS MER

  5. 4. Transport mode inference by multimodal map matching and sequence classification

    Master-uppsats, KTH/Geoinformatik

    Författare :Bruno Salerno; [2020]
    Nyckelord :transport mode inference; multimodal map matching; sequence classification;

    Sammanfattning : Automation of travel diary collection, an essential input for transport planning, has been a fruitful line of research for the last years; in particular, concerning the problem of automatic inference of transport modes. Taking advantage of technological advance, several solutions based on the collection of mobile devices data, such as GPS locations and variables related to movement (such as speed) and motion (e.

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

    Master-uppsats, Linköpings universitet/Programvara och system

    Författare :Hugo Lindholm; [2019]
    Nyckelord :map matching; hmm; hidden markov model; gnss;

    Sammanfattning : 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. LÄS MER
