  1. 1. Lens Distortion Correction Without Camera Access

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Emily Olsson; [2022]
    Nyckelord :Lens distortion; Lens distortion correction; Perspective n-Point; Camera calibration;

    Sammanfattning : Lens distortions appear in almost all digital images and cause straight lines to appear curved in the image. This can contribute to errors in position estimations and 3D reconstruction and it is therefore of interest to correct for the distortion. If the camera is available, the distortion parameters can be obtained when calibrating the camera. LÄS MER

  3. 2. Developing a technique for combining light and ultrasound for deep tissue imaging

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Meng Li; [2018]
    Nyckelord :UOT; Ultrasound Optical Tomography; Monte Carlo; TCSPC; PTOF; Photon time of flight; Ultrasound; US; AOT; Acousto-optical tomography; Spectral hole burning; SHB; ultrasound modulation; Physics and Astronomy;

    Sammanfattning : Biological tissues are strongly light-scattering and absorbing media that limit the depth of optical-based imaging. Even though, optical imaging provides good optical contrast information of biological content that is beneficial for clinical diagnostics application. LÄS MER

  4. 3. Measuring dimensions of goods modules with 2D laser scanners on a conveyor belt

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Filip Strandberg; Johan Freij; [2017]
    Nyckelord :2D laser scanner; LMS100; dimensions measuring; Raspberry Pi 3; SDL; 2D-laserskanner; LMS100; dimensionsmätning; Raspberry Pi 3; SDL;

    Sammanfattning : A company wants to measure and verify the size of goods modules, transported on a conveyor belt, with the help of two 2D laser scanners (LMS100). The resulting measurements will be written to a database whereafter the modules will be moved by an automatic lifting device to a storage. LÄS MER

  5. 4. Anomaly Detection for Product Inspection and Surveillance Applications

    Master-uppsats, Linköpings universitet/Datorseende; Linköpings universitet/Tekniska fakulteten

    Författare :Peter Thulin; [2015]
    Nyckelord :Anomaly detection; product inspection; surveillance; computer vision;

    Sammanfattning : Anomaly detection is a general theory of detecting unusual patterns or events in data. This master thesis investigates the subject of anomaly detection in two different applications. The first application is product inspection using a camera and the second application is surveillance using a 2D laser scanner. LÄS MER

  7. 5. TREDIMENSIONELL RELATIONSHANDLING FÖR BEFINTLIG BYGGNAD

    Kandidat-uppsats, Institutionen för teknik och byggd miljö

    Författare :Nils Larsson; Caroline Jödahl; [2007]
    Nyckelord :TREDIMENSIONELL; LASERSKANNING; TOTALSTATION; RELATIONSHANDLING; RELATIONSINMÄTNING;

    Sammanfattning : En om- eller tillbyggnad av en byggnad kräver ofta att befintliga ritningar värderas med avseende på aktualitet och geometri. Ritningarna kan förekomma i form av 2D-ritningar eller som ett digitalt underlag. LÄS MER
