Methods of measuring in the Universe
KUČERA, Jan
The work deals with distance measuring in space. The first part is about evolution of space arrangement and dimension imaginations from ancient times until the 20th century. Also Aristarchos´ heliocentric model of the solar system is described in detail, including his quantitative estimates of the Moon and Sun distances and dimensions. Hipparchos´ and Ptolemaios´ geometric models are described in detail too. Great attention is given to a genesis of heliocentric theory of Nicolaus Copernicus. The second part deals with contemporary methods of distance measuring. The work proceeds systematically from distances in the solar system to distances between stars as far as to distances between galaxies and quasars. It was necessary to write also about physical principles because distance measuring is based on them. The part of the work is a large pictorial supplement with text comments.

Binocular vision
Němcová, Andrea ; Šanda, Jaroslav (referee) ; Fedra, Petr (advisor)
This bachelor thesis deals with the physiology of binocular vision for obtaining three-dimensional perception from two-dimensional images when using special glasses. It focuses on anatomy and physiology of the human eye and vision as inseparable parts of binocular vision, and on binocular vision as such. The work also mentions terms related to vision and describes the evolution of binocular vision during the human life. The important part of this thesis is the description of the emergence of three-dimensional perception from two two-dimensional pictures (stereogram). The thesis explains the principles of 3D projection methods, especially those which use active or passive glasses, and briefly describes the possibilities of 3D projection without glasses. The practical part includes a plan of capturing dynamic scenes where important parameters which affect the video capturing are described. The plan provides a description of a dynamic scene design with respect to the possibility of verification of human physiological parameters. Described scenes were captured by two identical cameras and edited in appropriate software. These videos were shown to a group of viewers whose task was to evaluate the videos from both subjective and objective points of view.

Binocular vision
Brňák, Jan ; Hozman, Jiří (referee) ; Fedra, Petr (advisor)
This masters thesis deals with the physiology of binocular vision people for obtaining two dimensional spatial perception of images with glasses. There are developed theoretical part of the physiology of vision, then writing available methods that are now widespread for obtaining stereoscopic scene. The work also describes shooting dynamic scene using a pair of identical cameras. It focuses mainly on OFF-AXES method and deals with the topic of the settings stereoscopic base. There is also realized a practical part, which works with the capture dynamic scenes using video cameras with a automatic control of cameras distance. Automatic control is performed using the parallel port and a stepper motor. For this purpose it is designed to work in hardware support and a program for mutual communication. Filmed a short movie was screened to a group and those observers evaluated the parameters that were specified in the created poll.

Binocular vision
Brichta, Tomáš ; Jehlička, Karel (referee) ; Fedra, Petr (advisor)
In this work I have been briefed by physiology of binocular vision for acquisition of three-dimensional perception from two-dimensional images using special glasses. At first I described optical organ, after it I described physiology of binocular vision. In the next part of my work I described stereoscopic imaging technology and their advantages and disadvantages. In the next part of this work I have designed method for measuring ideal distance between cameras for scanning and projection of stereoscopic image using program Inition StereoBrain Calculator. After scenes design I have collected visual data for creating 3D videos. This videos were been projected to the group of the viewers. Data from the viewers were been analyzed afterwards.

Binocular vision and anaglyph production
Pospíšil, Pavel ; Šanda, Jaroslav (referee) ; Fedra, Petr (advisor)
This work concerns physiology of binocular vision and stereovision. The main topic of this work is the production of anaglyphs. The first part introduces anatomy of the eyes and principle of binocular vision, which is the stereoscopic production based on. The second part introduces the individual methods, it's processes and technical implementation for three-dimensional presentation with focusing on answering questions connected with production of anaglyphs. At the same time the M-script ANAGLYPH was developed, which provides connection with two external cameras and becomes high-quality element of anaglyphs production. All anaglyphs were photographed with couple of Logitec C120 or couple of Canon 450D cameras. Final anaglyphs were presented to a group of observers and they were given question forms. Subjective opinions of observers were statistically analyzed. The electronic version of this work and all the files and data are included on attached DVD.

Processing of Stereoscopic Video Sequence
Hasmanda, Martin ; Šmirg, Ondřej (referee) ; Říha, Kamil (advisor)
The main goal of this master’s thesis was get up used methods for observation the stereoscopic scene with one couple of cameras and find out good solving for processing these resulting pictures for two-view and multiple-view autostereoscopic displays for three-dimensional perception. For methods for acquisition video was introduced two methods. They were method “Off-axis” with parallel camera axis and method “Toe in” with intersections axis. For fit method was choice the method named as “Off-axis“. It was not produces the vertical parallax and in detail was in this work described principle of this method. Further were describe principles off used methods for three-dimensional perception namely from the oldest method named anaglyph after methods for viewing at autostereoscopic displays. The Autostereoscopic displays were main goal of this thesis and so their principles were described in details. For production the result image for autostereoscopic displays was used generation intermediate images between left and right camera. Resulting videos were acquisition for testing scene in created in 3D studio Blender, where was possible setting system of cameras exactly parallel axis. Then were introduce principles processing video where was extract from the couple of cameras where were connected to PC for help digitizing card and next time with two web cameras. Here is not guaranteed exact parallel axis system. Therefore this work try for real cameras achieve exactly parallel axis system by the help of transformations of frames with stereo rectification. Stereo rectification was solving with OpenCV libraries and was used two methods. Both methods work from principles epipolar geometry that was described in this work also in detail. First method rectifies pictures on the basis fundamental matrix and found correspondences points in two images of the scene and second method rectifies pictures from knowledge intrinsic and extrinsic parameters of stereoscopic system of cameras. In the end of this work was described application for implementation introduced methods.

Mathematical Methods and Exercises in Astronomy
BROM, Jiří
The aim of this thesis is to create collections of examples for the subject Astronomy taught for students of pedagogical faculties, studying this discipline as a part of physics courses. Due to very different mathematical knowledge of students I have chosen typical and not much difficult examples oriented to several branches of astronomy. Each part of examples begins with a self-contained theoretical introduction. The difficulty rises gradually from trivial to more complicated examples. The examples are mainly focused on motions in radial gravitational fields.
