  1. 1. Acoustic-Inertial Forward-Scan Sonar Simultaneous Localization and Mapping

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

    Författare :Aldo Teran Espinoza; [2020]
    Nyckelord :;

    Sammanfattning : The increasing accessibility and versatility of forward-scan (FS) imaging sonars (also known as forward looking sonars or FLS) has spurred the interest of the robotics community seeking to solve the difficult problem of robotic perception in low-visibility underwater scenarios. Processing the incoming data from an imaging sonar is challenging, since it captures an acoustic 2D image of the 3D scene instead of providing straightforward range measurements like other sonar technologies do (e.

  3. 2. CUDA Accelerated 3D Non-rigid Diffeomorphic Registration

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :An Qu; [2017]
    Nyckelord :diffeopmorphic demons; non-rigid image registration; parallel programming; GPGPU; IGI;

    Sammanfattning : Advances of magnetic resonance imaging (MRI) techniques enable visualguidance to identify the anatomical target of interest during the image guidedintervention(IGI). Non-rigid image registration is one of the crucial techniques,aligning the target tissue with the MRI preoperative image volumes. LÄS MER

  4. 3. Real-time Head Motion Tracking for Brain Positron Emission Tomography using Microsoft Kinect V2

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :Eleni Tsakiraki; [2016]
    Nyckelord :Microsoft Kinect sensor v2; Brain Positron Emission Tomography; head movements; Siemens High-Resolution Research Tomograph; Siemens ECAT HR PET system; Microsoft HD face; Matlab; head tracking accuracy; one-sample T-tests;

    Sammanfattning : The scope of the current research work was to evaluate the potential of the latest version of Microsoft Kinect sensor (Kinect v2) as an external tracking device for head motion during brain imaging with brain Positron Emission Tomography (PET). Head movements constitute a serious degradation factor in the acquired PET images. LÄS MER

  5. 4. Minimum hardware SfM/SLAM for sparse data point mapping of retail stores

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Daniel Falk; [2016]
    Nyckelord :structure from motion; simultaneous localization and mapping; generalized imaging device; camera pose estimation; sparse data; point clouds; path planning; artificial intelligence; intelligent agent; line following; navigation; computer vision; cognitive science; stroke width transform; Technology and Engineering;

    Sammanfattning : This report aims to compare methods that can be used to efficiently and accurately map digital price labels position in 3D space using a mobile robotic platform equipped with camera vision in a retail environment. The robotic platform built during the project uses four wide angle cameras to cover the full circular view in the horizontal plane. LÄS MER

  7. 5. Real-time Embedded Panoramic Imaging for Spherical Camera System

    Kandidat-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap
