  1. 1. Camera Modelling and Calibration with Machine Vision Applications

    Författare :Anders Ryberg; Bengt Lennartson; Anna-Karin Christiansson; Anders Heyden; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Camera model; Camera calibration; Fisheye camera; Catadioptric camera; Stereo vision; Other technology; Övriga teknikvetenskaper; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Camera modelling and calibration are important parts of machine vision. They can be used for calculating geometric information from images. A camera model is a mathematical projection between a 3D object space and a 2D image. LÄS MER

  3. 2. Camera Modelling and Calibration for Machine Vision Applications

    Författare :Anders Ryberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Camera Calibration; Camera Modelling; Stereo Vision; Machine Vision; Pose Measurement; Computer Vision;

    Sammanfattning : This thesis describes camera based methods for determining positions and orientations of objects in 3D-space. These methods are useful in several applications where camera images are used for acquiring information about the surroundings, and the targeted application here is guiding robots using a camera mounted on the robot hand.

  4. 3. Low Rank Matrix Factorization and Relative Pose Problems in Computer Vision

    Författare :Fangyuan Jiang; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Geometric Computer Vision; Low-rank Matrix Factorization; Relative Pose;

    Sammanfattning : This thesis is focused on geometric computer vision problems. The first part of the thesis aims at solving one fundamental problem, namely low-rank matrix factorization. We provide several novel insights into the problem. In brief, we characterize, generate, parametrize and solve the minimal problems associated with low-rank matrix factorization. LÄS MER

  5. 4. Vision-based Localization and Attitude Estimation Methods in Natural Environments

    Författare :Bertil Grelsson; Michael Felsberg; Per-Erik Forssén; Joni Kämäräinen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Over the last decade, the usage of unmanned systems such as Unmanned Aerial Vehicles (UAVs), Unmanned Surface Vessels (USVs) and Unmanned Ground Vehicles (UGVs) has increased drastically, and there is still a rapid growth. Today, unmanned systems are being deployed in many daily operations, e.g. LÄS MER
