  1. 1. Deep Learning-Based Depth Estimation Models with Monocular SLAM : Impacts of Pure Rotational Movements on Scale Drift and Robustness

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Daniel Bladh; [2023]
    Nyckelord :Deep Learning; Computer Vision; Monocular; SLAM; Depth Estimation;

    Sammanfattning : This thesis explores the integration of deep learning-based depth estimation models with the ORB-SLAM3 framework to address challenges in monocular Simultaneous Localization and Mapping (SLAM), particularly focusing on pure rotational movements. The study investigates the viability of using pre-trained generic depth estimation networks, and hybrid combinations of these networks, to replace traditional depth sensors and improve scale accuracy in SLAM systems.

  3. 2. Visual-Inertial SLAM Using a Monocular Camera and Detailed Map Data

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Viktor Ekström; Ludvig Berglund; [2023]
    Nyckelord :SLAM; localisation; monocular camera; GTSAM; factor graphs; iSAM2;

    Sammanfattning : The most commonly used localisation methods, such as GPS, rely on external signals to generate an estimate of the location. There is a need of systems which are independent of external signals in order to increase the robustness of the localisation capabilities. LÄS MER

  4. 3. Jämförelse mellan gradient AK/A-kvot och beräknad AK/A-kvot mellan tre forimätningsmetoder

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för medicin och optometri (MEO)

    Författare :Jonna Karlsson; Maja Forsman; [2023]
    Nyckelord :AK A; ackommodation; vergenser; heterofori; von Graefe; Modifierad Thorington; Maddox Rod; binokulärseende; konvergens; divergens;

    Sammanfattning : Bakgrund: Vergenser är ögonrörelser där ögonen rör sig i olika riktningar i relation till varandra. Sambandet mellan konvergens och ackommodation kallas AK/A-kvot. Det kan tas fram med beräknad eller gradientmetod. Den beräknade metoden baseras på avstånds- och närforier. LÄS MER

  5. 4. ROS-based implementation of a model car with a LiDAR and camera setup

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Marcus Nises; [2023]
    Nyckelord :LiDAR; ROS; stereoscopic camera; SLAM; Linux; rplidar a1; raspberry pi;

    Sammanfattning : The aim of this project is to implement a Radio Controlled (RC) car with a Light Detection and Ranging (LiDAR) sensor and a stereoscopic camera setup based on the Robot Operating System (ROS) to conduct Simultaneous Localization and Mapping (SLAM). The LiDAR sensor used is a 2D LiDAR, RPlidar A1, and the stereoscopic camera setup is made of two monocular cameras, Raspberry Pi Camera v2. LÄS MER

  7. 5. Monocular 3D Human Pose Estimation

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

    Författare :Robert Rey; [2023]
    Nyckelord :3D Human Pose Estimation; Monocular Images; Deep Learning; Artificial Neural Networks; 3D Människokroppspositionsuppskattning; Monokulära bilder; Djupinlärning; Konstgjorda neurala nätverk;

    Sammanfattning : The focus of this work is the task of 3D human pose estimation, more specifically by making use of key points located in single monocular images in order to estimate the location of human body joints in a 3D space. It was done in association with Tracab, a company based in Stockholm, who specialises in advanced sports tracking and analytics solutions. LÄS MER
