  1. 1. Alignment of Image Sensor using Piezoelectric Crystals

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Julia Jakobsson; Reem Chahrour Muhieddine; [2023]
    Nyckelord :piezo; piezoelectric; crystal; piezoelectric crystal; piezoelektrisk; kristall; piezoelektrisk kristall; camera; kamera; focus; fokus; Axis; Axis Communications; alignment; justering; prototyp; prototype; algorithm; algoritm; Technology and Engineering;

    Sammanfattning : The use of piezoelectric crystals as a way to achieve automatic alignment of an image sensor in a camera was investigated in collaboration with Axis Communications AB. Piezoelectric crystals can be created into different configurations, piezoelectric stacks being one of the simpler ones. LÄS MER

  3. 2. Using Optical Flow to provide robustness for animage sensor based multiangulation positioning system

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Fredrik Anderson; [2022]
    Nyckelord :;

    Sammanfattning : The use of image sensors in positioning systems has increased significantly the last years, spanning from complex SLAM-systems to simpler triangulation based methods. In the latter case, occlusion of anchor points may render the triangulation unsolvable, and any practical implementation must address this problem. LÄS MER

  4. 3. PreCro : A Pedestrian Crossing Robot

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :EBBA HEDBERG; LINNEA SUNDIN; [2020]
    Nyckelord :mechatronics; Pixy2; vision sensor; magnetic encoders; pedestrian crossing; mekatronik; Pixy2; bildsensor; magnetisk givare; övergångsställe;

    Sammanfattning : For people who suffer from visual impairment, getting around in traffic can be a great struggle. The robot PeCro, short for Pedestrian Crossing, was created as an aid for these people to use at pedestrian crossings equipped with traffic lights. LÄS MER

  5. 4. En metodutveckling för att finna normativ vitbalans i digitala kameror

    Kandidat-uppsats, Högskolan Dalarna/Bildproduktion

    Författare :Viggo Söderberg; Tilde Hernström; [2020]
    Nyckelord :Bildsensor; vitbalans; gråkort; bildbrus; digitalkamera; temperatur.;

    Sammanfattning : Denna text syftar på att framställa en metod som ska kunna användas för att ta reda på endigital kameras normativa vitbalans. Genom en experimentell metod filmar tre olika kameroren testtavla ljussatt för olika temperaturer vid olika vitbalanser. LÄS MER

  7. 5. Calibration using a general homogeneous depth camera model

    Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Daniel Sjöholm; [2017]
    Nyckelord :;

    Sammanfattning : Being able to accurately measure distances in depth images is important for accurately reconstructing objects. But the measurement of depth is a noisy process and depth sensors could use additional correction even after factory calibration. We regard the pair of depth sensor and image sensor to be one single unit, returning complete 3D information. LÄS MER
