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.

Automatization of 3D stacking process
Kamenec, Jan ; Řezníček, Michal (referee) ; Buršík, Martin (advisor)
The task of my thesis was to automate the process of 3D stacking. The work includes design of complex control board, that will serve as a control unit and provide a comprehensive function of mechanical displacement in combination with digital image acquisition. In addition, the electronics for controlling a stepper motor, PCB and the design. The result of this is a facility that provides automatic acquisition of images with different depth of field.

Drive of peristaltic pump for medicine
Smrž, Ondřej ; Procházka, Petr (referee) ; Huzlík, Rostislav (advisor)
This work is focused on the design of the peristaltic pump drive for medical purposes. Its initial goal is closer introduction of peristaltic pumps and stepper motors. Then the design of BLDC motor will be made and the use of this motor will be compared with stepper motor. Design of the BLDC motor will be made using RMxprt. Last but not least simulations of both types of motors for the peristaltic pump will be created in Simplorer. Finally, the program LabVIEW will be introduced and a program for controlling a stepper motor will be created.

Quantum efficiency measurement of optoelectronic components and development of experimental equipment
Lipr, Tomáš ; Palai-Dany, Tomáš (referee) ; Macků, Robert (advisor)
This thesis deals with the issue of quantum efficiency measurement of optoelectronic devices. The physical nature of silicon solar cells is explained here. In addition, the quantum efficiency as a concept is introduced. There is also discussed the influence of a solar cell semiconductor structure on the quantum efficiency itself. Furthermore, the thesis is focused on the design of an experimental set-up for automated measurement and data acquisition. The final realization of the step motor control unit is described in detail. It includes local and/or remote operations, design and development motivation. The next chapter is dedicated to analysis of the Matlab source code for remote operation, data acquisition and presentation. The final part of the thesis gives attention to experiments with real structures, not only the solar cells. The obtained results of analyzed measurements are presented at the conclusion.

HMI automatic tester
Lang, Stanislav ; Žalud, Luděk (referee) ; Macho, Tomáš (advisor)
This thesis is dedicated to the automation of tests of the thermostats developed by the company Honeywell. The first chapter presents a problem of self-testing of thermostats, followed by a discussion of possible approaches to solutions. Attention is paid to testing the functionality of the HMI of thermostats, especially to the part of the system, that deals with activation of touchscteen, but no other part of the problem are omitted in the text. Discussions of the problematic passes into the design and implementation of specific design solutions. The selected design of 3D-router, which moves in three orthogonal coordinates and resembles to a coordinate drill for example. First, it describes the basic concepts of mechanic and electronic part of equipment, and subsequently is designed and implemented control electronics for mechanical activator HMI. Each of the electronics components are described in detail and values of parts are based on the calculation with the exception of finished parts. The proposal of the electronics follows the possibility of maximization of universality module for applications in similar applications. The functionality of the electronics is controlled by a microprocessor with a custom program that is described in the work. Source code of some the programs is not available because it is know-how of the company. Next part of the thesis deals with optimization of the moving of axes, optimization is done empirically by measuring. An important issue is compliance with the accuracy required position, also part of the work is devoted to the issue of calibration position. Finally is solved the continuity on the superior system. It is designed and implemented the upper layer of the communication protocol used in the company. Work is the solution of specific corporate award thesis. Although it is a very specific role of the works are generally applicable for other applications. In particular, the proposed electronic represents relatively universal controller for stepper motor control.

Project of Engraving device for graphics creation
Hložek, Vojtěch ; Richter, Miloslav (referee) ; Horák, Karel (advisor)
The objective of this master's thesis is to design and implement a system which would be able to transfer a picture (either a bitmap or a vector image) on a foundational material. The main part of the apparatus consists of a plotter controlled by two stepping motors. The engraving itself is provided by a marker mounted to a movable part of engraving head. There was a PCB created for controlling the entire system. It contains power supplies, a microcontroller and motor and engraving head controlling circuits. The second part of the thesis shows a microcontroller program and a user interface in a PC. The image is trasfered from the PC into the microcontroller where it is processed and, based on the controlling program, engraved to the material.

Position system design
Balogh, Jaroslav ; Čížek, Martin (referee) ; Čech, Petr (advisor)
The purpose of this diploma thesis was to explore possibilities, design and build 2D position system driven by PC via USB. ATmega16 and FT232R were used as the most important parts of hardware solution. Software for control of the position system was designed in C++ Builder and it can run under MS Windows XP. This work is based on semestral thesis and in future can be used in other applications or modified. 2D position system will be later used by UBMI in education and scientific applications.

Digital data recorder
Müller, Tomáš ; Skapa,, Jan (referee) ; Diblík, Jan (advisor)
This thesis deals with method of measuring optical beam intensity, searching for communication system beam using stepper motor movement of the optical head and processing measured signal for displaying on PC. The basic theory of optoelectronics is shown here concerning the problem. There is elaborated main principles of photodetector and stepper motor mainly, which are main part of device. The second part of work is theoretical design of data recorder. All parts are described individually-their characteristics and conditions for correct usage. In the last part setup of device is explained, with the references to blocks of written programs. In the last part, main funcrions of system, its hardware managing and communication are described. At the very end of thesis, examples of measured data are presented.
