  1. 1. Helping robots help us : Using prior information for localization, navigation, and human-robot interaction

    Författare :Malcolm Mielle; Martin Magnusson; Achim Lilienthal; Erik Schaffernicht; Marjorie Skubic; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; graph-based SLAM; prior map; sketch map; emergency map; map matching; graph matching; segmentation; search and rescue;

    Sammanfattning : Maps are often used to provide information and guide people. Emergency maps or floor plans are often displayed on walls and sketch maps can easily be drawn to give directions. However, robots typically assume that no knowledge of the environment is available before exploration even though making use of prior maps could enhance robotic mapping. LÄS MER

  3. 2. Some Aspects of Mobile Map Services

    Författare :Hanna Stigmar; Fastighetsvetenskap; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amount of information; information services; cartography; map; mobile map services; usability;

    Sammanfattning : The technology of today, with the use of computers and the Internet, has enabled new types of map usage. Screen maps provide possibilities that could never be offered by standard paper maps, and allow maps to be integrated into information services. LÄS MER

  4. 3. Efficient Map Matching and Discovery of Frequent and Dominant Movement Patterns in GPS Trajectory Data

    Författare :Can Yang; Yifang Ban; Gyözö Gidofalvi; Xiaoliang Ma; Mirco Nanni; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; map matching; contiguous sequential pattern mining; contiguous sequential pattern comparison; movement pattern detection; Kartmatchning; sammanhängande sekventiellt mönster utvinning; sammanhängande sekventiellt mönster jämförelse; rörelsemönster detektering; Geoinformatics; Geoinformatik;

    Sammanfattning : The wide deployment of Global Positioning System (GPS) sensors for movement data collection has enabled a wide range of applications in transportation and urban planning. Frequent and dominant movement patterns embedded in GPS trajectory data provide valuable knowledge including the spatial and temporal distribution of frequent routes selected by the tracked objects and the regular movement behavior in certain regions.

  5. 4. Road network and GPS tracking with data processing and quality assessment

    Författare :Xiaoyun Zhao; Johan Håkansson; Kenneth Carling; Bin Jiang; Högskolan Dalarna; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GPS tracking; Reliability; Road network; visualized map; road network; Map-matching; P-median Model; Network density; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Sammanfattning : GPS technology has been embedded into portable, low-cost electronic devices nowadays to track the movements of mobile objects. This implication has greatly impacted the transportation field by creating a novel and rich source of traffic data on the road network. LÄS MER

  7. 5. Mapping and Merging Using Sound and Vision : Automatic Calibration and Map Fusion with Statistical Deformations

    Författare :Gabrielle Flood; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time of arrival; TOA; Time-difference of arrival; TDOA; Subsample methods; Uncertainty measure; Constant offset; RANSAC; Map merging; Map fusion; Change detection; Collaborative SLAM; Structure from motion; SfM; SLAM; Mapping; Localisation; Registration; Sparse maps; Point clouds;

    Sammanfattning : Over the last couple of years both cameras, audio and radio sensors have become cheaper and more common in our everyday lives. Such sensors can be used to create maps of where the sensors are positioned and the appearance of the surroundings. LÄS MER
