  1. 1. LiDAR-Equipped Wireless Sensor Network for Speed Detection on Classification Yards

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

    Författare :Isak Olsson; André Lindgren; [2021]
    Nyckelord :LiDAR; Internet of Things IoT ; Wireless Sensor Networks WSN ; Classification yards; 6LoWPAN; RANSAC; LiDAR; Sakernas internet; Trådlösa sensornätverk; Rangerbangårdar; 6LoWPAN; RANSAC;

    Sammanfattning : Varje dag kopplas tusentals godsvagnar om på de olika rangerbangårdarna i Sverige. För att kunna automatiskt bromsa vagnarna tillräckligt mycket är det nödvändigt att veta deras hastigheter. En teknik som har blivit populär på sistone är Light Detection and Ranging (LiDAR) som använder ljus för att mäta avstånd till objekt. LÄS MER

  3. 2. Boundary Representation Modeling from Point Clouds

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Oskar Aronsson; Julia Nyman; [2020]
    Nyckelord :Point Cloud; Photogrammetry; RANSAC; Modeling; Bridge Inspection; Boundary Representation; Punktmoln; Fotogrammetri; RANSAC; Modellering; Brobesiktning; BREP;

    Sammanfattning : Inspections of bridges are today performed ocularly by an inspector at arm’s lengths distance to evaluate damages and to assess its current condition. Ocular inspections often require specialized equipment to aid the inspector to reach all parts of the bridge. LÄS MER

  4. 3. 3D Modeling of Indoor Environments

    Master-uppsats, Reglerteknik; Tekniska högskolan

    Författare :Johan Dahlin; [2013]
    Nyckelord :Point Cloud; 3D Model; Topology; Random Sample Consensus; Principal Component Analysis;

    Sammanfattning : With the aid of modern sensors it is possible to create models of buildings. These sensorstypically generate 3D point clouds and in order to increase interpretability and usability,these point clouds are often translated into 3D models.In this thesis a way of translating a 3D point cloud into a 3D model is presented.

  5. 4. Road Surface Modeling using Stereo Vision

    Master-uppsats, Reglerteknik; Tekniska högskolan

    Författare :Mattis Lorentzon; Tobias Andersson; [2012]
    Nyckelord :Stereo camera; Digital Elevation map; Temporal filtering; Curb detection; Road surface classification; Random sample consensus; Conditional random fields; Obstacle detection;

    Sammanfattning : Modern day cars are often equipped with a variety of sensors that collect information about the car and its surroundings. The stereo camera is an example of a sensor that in addition to regular images also provides distances to points in its environment. LÄS MER

  7. 5. Navigation in collection of Photos

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Venkata Raja Vamsi Sankar Veguru; Raghavendra Surampally; [2011]
    Nyckelord :SIFT; RANSAC; Fundamental Matrix; Navigation; Automatic Image Similarity Measure; 3D Controls;

    Sammanfattning : We present a methodology to navigate viewing of a city block or any realistic outdoor structure by collection of images. The methodology implement intuitive navigation commands like as left, right, forward or backward to change the viewing position. LÄS MER
