Uniform Marker Field na válci

Abstract

This work presents a new extension for Uniform Marker Field, which is able to detect UMF on the cylinder. First part of the text deals with Augmented reality and focuses on systems using markers. It discusses the actual state-of-the-art systems and its possibilities. After that it focuses more deeply on the marker system Uniform marker field and its grayscale variants. Next part of the work describes properties of the cylinder projected in real space. Important properties for detecting are discussed in detail. Then the proposal and description of detection algorithm is presented. Implementation of algorithm is tested and evaluated on the very end of this thesis.

Práce se zabývá rozšířením Uniform marker fields o možnost detekování na válci. V úvodu pojednává obecně o rozšířené realitě se zaměřením na systémy využívající markery. Diskutuje současné state-of-the-art systémy a jejich možnosti. Poté se podrobněji zabývá typem markerů Uniform Marker Field se zaměřením na jejich detekci. Zmiňuje i variantu pracující v odstínech šedi. Dále jsou v práci popsány některé zákonitosti projekce válce v reálném prostoru se zaměřením na vlastnosti, které lze využít k detekci markerů na plášti válce. Následuje návrh a popis konkrétní podoby detekčního algoritmu. Na závěr je implementace detektoru otestována a zhodnocena.
