Robotic Table Football
Jediný, Lukáš ; Zuth, Daniel (referee) ; Lang, Stanislav (advisor)
The focus of this thesis is design and production of a robotic table football. The aim of the thesis is to select a camera and a lens and to devise lighting. The data from the camera require proper processing to assess the location of the ball, based on which the game algorithm controls the movement of the robotic players. Inherent part of the thesis is testing the player control algorithm using a simple simulation.

3D Photo Slideshow Using OpenGL
Dokoupil, Martin ; Fapšo, Michal (referee) ; Seeman, Michal (advisor)
This document describes implementation of photo slideshow editor. This editor can be used to create dynamic sequences from taken photos. Image taken by camera is projected onto three-dimensional sphere and drawn to screen. Then it is posible to rotate and zoom camera over image. Visual output of this editor makes moving over image more real. If panoramic image is used, user is able to free look around. This document describes method which can translate two-dimensional coordinates to three-dimensional space. Shows how to use transformations for moving camera and methods to implement camera zoom. Contains description of user interface and also mentions extensions that were implemented in editor.

Lens Distortion Correction
Doležel, Michal ; Seeman, Michal (referee) ; Šiler, Ondřej (advisor)
The bachelor thesis deals with methods of removing digital photographies aberrations caused by photographical lens distortions. It describes the most frequent lens aberrations, deals with their causes, followed by consequences of these aberrations on destination pictures and ways of their removing from digital photographies. The main goal of the thesis is to design and implement tools for removing lens distortions aberrations from a digital photography. The application was created in C++ programming language with the support of Cimg and Imagemagick libraries. The application was also developed and tested for MS Windows XP and Linux Kubuntu 7.10 operation systems. The results are compared with professional tools for digital photography processing.

Camera calibration
Opravil, Jan ; Babinec, Tomáš (referee) ; Richter, Miloslav (advisor)
Imperfection of some lenses used in industrial cameras is distracting. This thesis is concerned with the calibration of cameras with geometric barrel or cushiontype distortion. In the calibrating process is used a function which approximates real lens distortion. To calculate the coefficients of this function the straight line sections in the distorted image are used. Those detected lines play the key role and they ought to have the greatest possible information bias. To enhance the quality of detection are chosen some methods of preprocessing. The algorithms thus created are tested first on an artificially generated calibers and later on real ones. The program is written in C and is using some of the functions of the OpenCV library.

Placement Optimization of Projector Lens
Bezděk, Matěj ; Važík, Jiří (referee) ; Novotný, Pavel (advisor)
This diploma thesis deals with the creation of engineering design of holder of projector lens. The thesis is created in cooperation with department of development in Varroc Lighting Systems, s.r.o. Initial part provides a brief description of the development of lighting technology used in car´s headlamps. The following part describes solutions currently used in clamping the lens in holder. The main part of the thesis focuses on the design of holder of projector lens itself. Projector lenses testing provide critical values of cohesive failure of the lens material, which cannot be exceed during the process of lens fitting and its subsequent clamping. In the final part the engineering design is verified and optimized using finite element analysis.

Evaluation of optical components for LED
Dobiáš, Jiří ; Pavelka, Tomáš (referee) ; Škoda, Jan (advisor)
This thesis deals with an evaluation of optical components for LED, which is based on laboratory measurements of available LED samples and optical elements. The evaluation is done according to established standards and is focused on efficiency and adjustment of luminous flux (beam angle, luminous curve). Furthermore was made a study engaged in an optical element influence on LED color properties (color temperature, spectral characteristics). In conclusion there is an optical elements usage overview and recommended procedure for selecting appropriate combination of LED and optical element.
