  1. 1. 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. 2. Single image scene-depth estimation based on self-supervised deep learning : For perception in autonomous heavy duty vehicles

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : Yegor Piven; [2021]
    Keywords : computer vision; machine learning; deep learning; depth estimation; single image depth estimation;

    Abstract : Depth information is a vital component for perception of the 3D structure of vehicle's surroundings in the autonomous scenario. Ubiquity and relatively low cost of camera equipment make image-based depth estimation very attractive compared to employment of the specialised sensors. READ MORE

  4. 3. Triple-Camera Setups for Image-Based Depth Estimation

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Altin Januzi; [2020]
    Keywords : ;

    Abstract : This study was conducted as to attempt to find whether a three-camera setup could improve depth map retrieval as opposed to a two-camera setup. The study is based on three main ideas to exploit information from the additional camera. READ MORE

  5. 4. Potentialities of Unmanned Aerial Vehicles in Hydraulic Modelling : Drone remote sensing through photogrammetry for 1D flow numerical modelling

    University essay from KTH/Byggvetenskap

    Author : Andrea Reali; [2018]
    Keywords : UAV; remote sensing; structure from motion; photogrammetry; 1D steady flow hydraulic numerical modelling; hydraulic modelling;

    Abstract : In civil and environmental engineering numerous are the applications that require prior collection of data on the ground. When it comes to hydraulic modelling, valuable topographic and morphology features of the region are one of the most useful of them, yet often unavailable, expensive or difficult to obtain.

  6. 5. Infrared image-based modeling and rendering

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : Oskar Wretstam; [2017]
    Keywords : scene reconstruction; structure from motion; multi-view stereo; image-based modeling; infrared thermography; infrared images; computer vision;

    Abstract : Image based modeling using visual images has undergone major development during the earlier parts of the 21th century. In this thesis a system for automated uncalibrated scene reconstruction using infrared images is implemented and tested. An automated reconstruction system could serve to simplify thermal inspection or as a demonstration tool. READ MORE
