Lokalizace na bázi Bluetooth
Machyňák, Augustin ; Rozman, Jaroslav (referee) ; Janoušek, Vladimír (advisor)
The thesis deals with the development of a device localization system using ESP. The system uses signal strength information to estimate the distance and then uses multilateration techniques to estimate device positions. To obtain the relative positions of the receivers it also uses signal strength, making it very user friendly to setup and configure. The resulting positions are either processed on the ESP itself with simple visualization or it is possible to use an external server implementation to process them with historical data and a more suitable visualisation of the positions. However, the accuracy is not satisfactory and only suggests the use of map generating techniques for each specific environment using which to determine, what combinations of received signal strength values correspond to each position is a more appropriate method for localization.

Development of System for Landmine Detection
Šmelka, Martin ; Kubíček, Michal (referee) ; Doležal, Tomáš (advisor)
The Bachelor's thesis will cover a proposal for the construction of a demonstration system designed to discover objects that represent hidden „mines“ in a field. In the first phase, a systém will be designed to simulate the behaviour of the final device using the MATLAB interface. The proposed code will generate a GUI that will simulate the system in the field. After discovering a mine, the assigned cell will be marked, and the location will be signalled to the operator. Afterwards, the design of the demonstrator will be conceptualised and a working prototype fabricated to verify the functionality of the proposal.

Automatická kontrola dopravního značení
Čechmánek, Roman ; Klíma, Ondřej (referee) ; Musil, Petr (advisor)
The aim of this work is to create a cost-effective tool capable that would be able to automate the process of traffic sign control. This includes working with records of drives on land communications, created using inexpensive recording devices such as GoPro action cameras or certain dashcams. The control is based on the system localized traffic signs and historical traffic sign mapping data. The result of the work is a system whose input consists of drive records and historical data, and whose output is two files containing information about the inspection results. The first of these is a GEOJSON file, suitable for further processing of the collected data, and an HTML file that provides a simple user interface visualizing the inspection results on an interactive web map.

Multiplayer game using player location
Nguyen, Hoang Nam ; Materna, Zdeněk (referee) ; Beran, Vítězslav (advisor)
This bachelor’s thesis examines the methodology for evaluating the functionality and user experience of a multiplayer mobile game using geolocation technologies. The study focuses on identifying key factors influencing the enjoyment and success of the game across different environments and player counts. The research sample consists of players of the mobile game from various locations. Through a questionnaire survey, the study analyzes how participants express their views on various aspects of the game and whether these aspects influence their overall impression and experience. The findings provide valuable insights into the factors contributing to the success of mobile games and can serve as a basis for further development and optimization of gaming applications.

Fiducial Marker-Based Localization System
Hála, David ; Horeličan, Tomáš (referee) ; Gábrlík, Petr (advisor)
This work deals with localization of the robot in space using optical markers. In the first part of the thesis, the reader is introduced to the problems and pitfalls of this project and all the important connections, both mathematical and physical, are explained. The second part then focuses on the description of the procedure that was chosen to design the program and the ideas that led to its completion.

Validation of the tool for localization of symmetrical and asymmetrical faults
Šmehlík, Daniel ; Jurák, Viktor (referee) ; Topolánek, David (advisor)
Disturbances in power systems that can cause widespread outages and limit power supply require rapid detection, location and elimination. Earth faults and short circuits, each with their own complications for localization, pose significant challenges to power operations. This thesis focuses on the validation of Vdip, a tool designed to efficiently locate these faults. The tool was tested in two simulation environments, RTDS and PSCAD, to simulate different fault scenarios and record data for analysis. These tests provided important information for evaluating the effectiveness of Vdip.

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.
