Localization system for mobile robot B2
Korytár, Lukáš ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
The master’s thesis implements localization and navigation routines for mobile robot B2 in order to operate autonomously in an environment described by a road map only. The ROS framework was used for developing new software. The research part describes possible approaches to localization problem and summarizes ROS packages with localization and navigation software. The following part includes communication with the robot’s sensor modules and data processing from LIDAR, IMU and camera. The localization package robot_localization based on Kalman filter is implemented and setting of the navigation stack navigation is proposed, aiming to robot’s autonomous outdoor navigation. Implemented functions were tested in park environment and they are evaluated in this master's thesis too.

Game Web Portal - Object-oriented Programming
Hůla, Vladimír ; Galáž, Zoltán (referee) ; Povoda, Lukáš (advisor)
This thesis deals with design and implementation of programming structure of game web portal. The web portal will serve as a communication and information center to simplify coordination among players and allow them to gain new experience. In the thesis are analyzed the needs of players, existing solutions and their drawbacks. The results of this analysis are used to design individual functions of the portal. Implementation of the most important parts of the website has been described, the implementation of these parts were evaluated and some enhancemets were eventually suggested. In the end of this thesis several functionalities were suggested, which could extend the portal in the future.

Hybrid module for industrial localization
Sedláček, Petr ; Fuchs, Michal (referee) ; Kubíček, Michal (advisor)
Tato diplomová práce si klade za cíl návrh hybridního lokalizačního zařízení, které je schopno lokalizace uvnitř i vně budov. Lokalizace uvnitř budov je dosažena pomocí technologie Ultra Wideband a venkovní lokalizace je provedena pomocí kombinace technologie RTK GNSS a PPP pomocí open - source softwaru zvaného RTKLIB. První část textu se zaměřuje na vysvětlení používaných technologií a výběr nejpřesnější technologie pro venkovní lokalizaci. Druhá část se zaměřuje ma vývoj potřebného hardware a software finálního zařízení a na integraci systému pro venkovní lokalizaci do systému pro lokalizaci vnitřní. Výstupem práce je plně funkční zařízení, které je schopné plynulé lokalizace uvnitř i vně budov. Funčnost celého zařízení je dokázána na finálních testech uskutečněných ve vnitřních i venkovních prostorách. Na závěr také práce zmiňuje možná vylepšení celého zařízení, která mohou být v budoucnu provedena.

Autonomous RC ship model
Jevická, Barbora ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This Master’s thesis deals with working on development kit, which is used for RC ship model. The basis are programmable Nucleo STM32 microcontrollers, to which other used modules are connected. The goal is to test each component and create system for navigation of the ship and wireless communication between controller and ship. GPS module and compass are used to navigate and determine the direction of the ship. Controller and ship can communicate through bidirectional wireless modules with antenna. The RC ship model can be switched between manual and autonomous modes. The main result of this thesis is autonomous movement of the ship on to a predetermined GPS coordinates and parallel communication with the user.

Robot for Robotour 2012
Vass, Robert ; Luža, Radim (referee) ; Rozman, Jaroslav (advisor)
The aim of this article is the theoretical analysis, proposal and implementation of a method for the operation of an autonomous robot for Robotour 2012 with the help of camera and sensor usage. Key issues to be faced are the computer vision, robot sensing uncertainty and the localization problem. Firstly, road extraction is achieved by using colour segmentation. Secondly, for the combination of information of different uncertain sources, Kalman Filter is proposed. Finally, the information received by the camera which serves for the building of an occupancy grid map corrected by sensors is de facto the representation of environment for the robot.

Analytical Dashboard for Indoor Locating System
Petrovič, Lukáš ; Ščuglík, František (referee) ; Veselý, Vladimír (advisor)
The main purpose of this work is to create an application which will provide visualisation of historical data from position sensors. The data are being obtained from closed spaces, for example shops, gymnasiums or halls. These data are valuable but without easily usable visualisation they will lose their potential. Right visualisation allows user to better evaluate situation which the data represents. Result of this work is a tool with which the user is able to easily analyse data gained in certain time interval. For the needs of analysis, the application provides various kinds of data representations, which assign the data specific purpose. Data might be presented in graphs for example for the purpose of representation of the total overcomed distance of monitored object. They can also be used in maps which provide good representation of positions due to monitored area. All created visualization elements are put into interactive blocks. These blocks make up almost whole control panel. It is easy to manipulate with these blocks and to edit created visualisation with their help.

LPR Recognition
Trkal, Ondřej ; Richter, Miloslav (referee) ; Horák, Karel (advisor)
The thesis deals with analysis and design of system for automatic localization and recognition of the license plate. The input images are from different sources, and contain large scenic and weather variations. The aim was to create a system able to find the licence plate on the image and recognize its alphanumeric figure. In this work, there is a focus on analysis and implementation of localization and optical character recognition methods. One own and four other localization methods are compared. There are also compared three classifiers for optical character recognition. Localization and OCR methods are tested on real data and evaluated in accordance with the calculated evaluation parameters. The work also contains sensitivity analysis of the proposed system.

Angle of arrival calculation methods for localization using UWB technology
Žaludek, Ivo ; Klusáček, Stanislav (referee) ; Havránek, Zdeněk (advisor)
The thesis describes UWB technology, compares available hardware platforms and describes UWB localization methods. The practical part compares the methods of calculating the angle of arrival from the phase difference of signal arrival on the two-element antenna array. The calculation is performed using the analytically obtained arc sine function and also using the look-up table and the polynomial function. The content of the look-up table and the coefficients of the polynomial function are based on the measured characteristics of the UWB receiver (anchor). The best result was obtained using the look-up table. More accurate results were obtained when the phase difference of arrival values were averaged.
