  1. 1. Multi-camera system for close-up supervision in test-fixtures using openCV and optics

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Henrik Liljefors; [2023]
    Keywords : Technology and Engineering;

    Abstract : The test-fixture is a device used for testing of electronic circuits in production, that is produced by the Lund based company mikrodust AB. In the test-fixture, cameras are both used for supervision of products-in-testing and in the products themselves. READ MORE

  3. 2. Camera Distortion Calibration through Fringe Pattern Phase Analysis

    University essay from Linköpings universitet/Datorseende

    Author : Karl Karlsson; [2023]
    Keywords : fringe-pattern; distortion; monogenic signal; phase analysis;

    Abstract : The goal of this thesis is to use fringe-pattern phase analysis to calibrate the distortion of a camera lens. The benefit of using this method is that the distortion can be calculated using data from each individual pixel and the methodology does not need any model. READ MORE

  4. 3. FPGA implementation of an undistortion model with high parameter flexibility and DRAM-free operation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Zacharie McCormick; [2023]
    Keywords : FPGA; Computer Vision; Lens correction; Remapping; FPGA; Datorseende; Linskorrigering; Omvandling;

    Abstract : Computer Vision (CV) has become omnipresent in our everyday life and it’s starting to see more and more use in the industry. This movement creates a demand for ever more performant systems to keep up with the increasing demands in manufacturing speed and autonomous behaviours. READ MORE

  5. 4. Preparations for photon external beam radiotherapy treatment planning of small animals

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Joanie Diha Guei; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction:The XenX is a small animal irradiation system that acquires high-resolution cone-beam tomography (CBCT) images of small animals and treats small animals with higher precision than medical linear accelerators. MuriSlice is a software for CBCT image reconstruction. READ MORE

  6. 5. Lens Distortion Correction Without Camera Access

    University essay from Linköpings universitet/Datorseende

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

    Abstract : 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. READ MORE
