System for processing of GPS data from multiple mobile devices
Jurča, Josef ; Červenka, Vladimír (referee) ; Lattenberg, Ivo (advisor)
The aim of this thesis was to create an information system which consists of a mobile application, server and web application. Mobile application is designed for operating system Android and it is used for sending GPS coordinates of mobile devices to the server. These data are later processed by server and stored in database. Web application displays the current location of mobile devices in user group on a map, it also displays location history and statistics. Accuracy of the station location can be enhanced by using DGPS assuming that one of stations in a group does not change its location. The system was designed and then developed using modern web technologies and frameworks including PhoneGap, Ionic, Node.js, Express, MongoDB, Mongoose and AngularJS. Further measurements, that were performed, are supposed to present the effect of DGPS to location accuracy determination.

Localization by SICK range-finder
Zháňal, Jan ; Věchet, Stanislav (referee) ; Marada, Tomáš (advisor)
Motion and localization are basic attributes of mobile robots in the environment. In this thesis we focus on localization and also mapping environment by one robot (named as well SLAM) which will use laser range-finder SICK. There will be stated a lot about activities related to robot movements’ i.e. odometry, maps and their making. There is Kalman Filter and his use in this document. In the end there will be made model of the SLAM method made by Matlab program.

Mapping Time of Creation of Multimedia File to Position where It Was Taken
Jurča, Josef ; Rozman, Jaroslav (referee) ; Horáček, Jan (advisor)
The aim of the bachelor thesis is to create a web application which enables uploading and localization of photographs and video sequences and displaying them on the map. The position of photos is to be extracted from its EXIF metadata. If necessary information is not contained in the EXIF metadata, coordinates are to be assigned by use of external log from GPS receiver and the time of creation of the photo. Location of photo is to be displayed with use of the points on the map. The GPS coordinates are to be assigned to the video with help of external GPS log and time of last modification of the file. The application is to enable displaying actual position and route during video playback. The thesis also describes formats of multimedia data and its metadata, the GPS system and possible ways of using the system. Afterwards existing solutions of localization of multimedia data on the map are compared and consequently it is focused on design and implementation of the new application. The thesis also deals with the process of testing of the final application and summarizes its software requirements and limits. In conclusion achieved solution is evaluated and proposals of future progress of the application are made. The outcome of the thesis is functional web application which enables user to upload multimedia data and subsequently assign their position and display them on the map.

Bifurcation Localization in Retina Images
Kvapilová, Aneta ; Drahanský, Martin (referee) ; Semerád, Lukáš (advisor)
This thesis deals with processing images of human retina. Its main goal is to create a system which is able to localize places important in a process of creating biometrical template - bifurcations and crossing of blood vessels. The first part focuses on biometrics in detail and explains certain concepts of this area. It also mentions the anatomy of the human eye focusing on retina. The second part provides detailed description of all the stages and algorithms that were necessary in the process of creation of the application.

Localization and its influence on other processes in a wireless network
Zemánek, Karel ; Šimek, Milan (referee) ; Morávek, Patrik (advisor)
The masters thesis concerns localization and its influence on other processes in a wireless network. The first part of the thesis is devoted to the study of localization algorithms in wireless sensor networks. The second and third part is devoted to the description of hierarchiacal aggragation and Greedy perimetr stateless rating (GPSR). The fourth part presents implementation of GPSR protokol into the MATLAB simulation tool. It contains the description of specific m-files, that are use for simulation. The fifth part deals with the simulation itself. And the final part presents simulation results.

Information System Assessment and Proposal of ICT Modification
Skopalík, Daniel ; Kindlová, Dita (referee) ; Koch, Miloš (advisor)
The diploma thesis deals with the discovery of flaws in the processes and information system with suggestions for improvement. The work is based on a localization company which operates worldwide and it is considered among the best in the field of localization. The thesis is divided into three parts. The first one is the theoretical framework which was used during analysis of the company and its information system and, consequently, is described in the second part of the work. The last and the most important part is a description of the current processes and a suggestion of changes in order to improve and increse the efficiency of these processes. Also, in this work, there is a time analysis with possible risks which may occur. At the end of the work, I deal with an economic assessment of the changes and their benefits for the society.

ROS framework utilization for autonomous mobile robot control system
Vávra, Patrik ; Krejsa, Jiří (referee) ; Appel, Martin (advisor)
Tato práce se zabývá vytvořením lokalizačního a navigačního systému mobilního robota pro vnitřní prostředí pomocí frameworku ROS. Stručně je zde představen projekt, v rámci kterého diplomová práce vznikla, a jeho cíle. V rešeršní části je v krátkosti popsán ROS framework, simulační prostředí Gazebo a senzory, kterými robot disponuje. Následuje vytvoření modelu robota a simulačního prostředí, v němž jsou vyzkoušeny lokalizační, navigační a další rutiny. V experimentální části je provedeno testování senzorů a popsáno využití jejich výstupů. Následně jsou upraveny a otestovány algoritmy ze simulace na reálném robotovi. V závěru jsou popsány vytvořené vzdělávací minihry. Hlavním výstupem této práce je funkční stavový automat, který umožňuje manuální ovládání, zadávání cílů pro navigaci a v případě potřeby zajistí autonomní nabití robota.

Video Games Localisation
Novotný, Tomáš ; Walek, Agata (referee) ; Šťastná, Dagmar (advisor)
Tato bakalářská práce se zabývá historií a problematikou lokalizace videoher. Práce se skládá ze dvou částí. První je teorie, která bude obsahovat počátek počítačových her až po přítomné videohry. Zároveň se bude zabývat lokalizací a problémy, které okolo ní jsou. Bude obsahovat termíny, které doprovází lokalizaci videoher jako jsou například transkreace, internacionalizace, uživatelské rozhraní, herní kód a spoustu dalších. Ukáže důležitost, proč by si měly společnosti dávat pozor na odlišnosti v kulturách a jaké mohou být následky. Druhá polovina se bude skládat z praktické části, kde se budou porovnávat různé hry a jejich způsob lokalizace.
