1. 16. 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

3. 17. Investigation of a New Method for Drone Dazzling Using Laser

   University essay from Linköpings universitet/Reglerteknik

   Author : Jens Grundmark; [2021]
   Keywords : Drone countermeasure; Risley prisms; Camera dazzling; Laser;

   Abstract : Drones have become more common, and are commercially available for consumers. Small drones can be used for unauthorized information gathering, or to cause disruptions. This has created a need for safe, effective countermeasures against drones. In this thesis, a method for countermeasures against drone imaging is investigated. READ MORE

Syftet är att undersöka hur fotografiska representationer påverkar bilden av ett landskap, samt hur kameran fungerar som ett verktyg för att inleda en dialog med landskapet. READ MORE

6. 20. Approaching Ground-Truth EntrancePupil Position For Mixed Reality Applications And The Possibilities Of Using Computer Vision To This End

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Ricardo Danza Madera; [2021]
   Keywords : ;

   Abstract : Given the requirement to increase the accuracy of eye tracking for mixed reality applications, it was necessary to develop a technology that could more accurately approach the ground-truth position of a human entrance-pupil. The goal was to use Computer Vision, in the forms of pairs of stereo-images of the eyes, to estimate said position of the entrance-pupil. READ MORE
