Visual Navigation of the Vehicle
Jaššo, Kamil ; Richter, Miloslav (referee) ; Horák, Karel (advisor)
The thesis consists of retrieval of known solutions of autonomous vehicle navigation. Thesis further describes options for controling autonomous vehicle, and using of sensors in autonomous vehicles. From different types of sensors are selected two types, that are most suitable for visual navigation of the vehicle. Thesis describes the function and way of using these two types of sensors in the visual navigation of the vehicle. The program for obtaining and saving data from selected sensors is also part of the thesis.

Path Planning using Voronoi Graphs
Živčák, Adam ; Uhlíř, Václav (referee) ; Rozman, Jaroslav (advisor)
The main purpose of this bachelor thesis is to design and implement plugin for robot operating system, which will be used for path planning using Voronoi graphs. Path planning is executed in well known world, about which robot knows where obstacles are placed. Thesis contains overview of main concepts of robot operating system, description of Voronoi graphs and algorithms to construct them. In conclusion is placed comparison of implemented plugin for path planning with ROS integrated planners.

Position measurement of moving objects using a robotic total station
Horeličan, Tomáš ; Žalud, Luděk (referee) ; Jílek, Tomáš (advisor)
Práca sa zaoberá objavujúcim sa nekonvenčným využitím moderných teodolitov, tiež známych ako Robotické Totálne Stanice (RTS), ako sledovací a navádzací systém, určením presnej pozície dynamicky sa pohybujúceho objektu. To sa týka najmä situácií, kde nie je možné využiť konvenčné polohovacie systémy akým je napríklad GNSS. Kinematicky určená poloha objektu kontinuálne sledujúcou RTS môže byť následne v reálnom čase využitá pre autonómnu navigáciu malých bezpilotných leteckých prostriedkov (UAV) poskytnutím referenčného súradnicového systému a okamžitej polohy v ňom. Podstatná časť práce je venovaná návrhu a realizácii vhodných experimentov, ktoré overia spoľahlivosť určovania presnej polohy objektu v presnom časovom okamžiku. Boli preverené stanice série S7 a S9 od spoločnosti Trimble a stanica S9 HP, ktorá disponuje frekvenciou kontinuálneho merania až do 10 Hz bola napokon využitá pre experimenty. Lokálny čas ovládacieho panelu TSC7, ktorý zabezpečuje komunikáciu so stanicou bol pomocou protokolu PTP synchronizovaný s lokálnym časom mini-počítača Raspberry Pi, ktorý následne poskytoval referenčné meranie skutočnej polohy objektu v čase. V závere sú zhrnuté výsledky experimentov.

Electronic Flight Bag
Kúšik, Lukáš ; Vlk, Jan (referee) ; Chudý, Peter (advisor)
Cieľom tejto diplomovej práce je vytvoriť Electronic Flight Bag (EFB) aplikáciu pre mobilné telefóny s operačným systémom Android. Pre splnenie tejto úlohy bola preskúmaná aktuálna legislatíva ohľadom EFB aplikácií spolu s najmodernejšími EFB aplikáciami dostupnými na aplikačnom trhu. Na základe týchto informácií je navrhnutá a implementovaná EFB aplikácia určená pre pilotov všeobecného letectva. Výsledný produkt obsahuje funkcie pre plánovanie letu, vlastnú leteckú mapu, pilotný denník, katalóg letísk s dátami z celého sveta a ďalšie. Podpora offline zaručuje funkčnosť v reálnych podmienkach letu. Konečný produkt sa taktiež snaží inovovať nad existujúcimi EFB aplikáciami zahrnutím funkcionalít, akými sú napríklad automatické kontrolné zoznamy a náhľad v rozšírenej realite.

Navigation in Public Transport
Turic, Matúš ; Křivka, Zbyněk (referee) ; Burget, Radek (advisor)
This master's thesis deals with the issue of traveling in public transport. In the first part the author informs about similar applications and theories necessary for understanding the problems. In the second part, the author describes the design and behavior of the mobile and server application, including the used technologies. Created mobile application has the task of navigating the user from one point to another in the shortest possible time, while it should be possible to replace the current route with faster one.

Mobile Devices Navigated by an Intelligent Network
Barna, Andrej ; Žák, Marek (referee) ; Zbořil, František (advisor)
This work studies the problem of indoor navigation, using wireless sensor networks. The knowledge of multiagent systems is being used in the process of solving this problem. Platform WSageNt, running on the operating system TinyOS, is being used for the execution of the agents. Agents themselves on the WSageNt platform are created in the language ALLL, which is described in the process. With use of those technologies, a solution is proposed as an extension to the WSageNt plaform and three agents, which fulfill the desired functionality. Then the implementation of this solution is described, followed by its testing, stating advantages and disadvantages of the created system.

Navigation System for Buildings on Mobile Device
Žiška, Peter ; Čadík, Martin (referee) ; Beran, Vítězslav (advisor)
This work is focused to suggest an approach, which simplifies creation of indoor navigation systems on mobile devices. The final solution is divided into two parts: an auxiliary tool for creating localization and navigation assets and mobile navigation application. The auxiliary tool creates assets needed to localize with the help of scanning surrounding access points in the place of user's standing in a building. The tool also generates navigational graph with cooperation of user and based on the geometric representation of building's rooms. The localization of a mobile device is based on WIFI fingerprinting method, which in the offline phase needs to have a map of fingerprints available. It is necessary to create this map manually. The tool will make easier for the user to create needed map and make deployment of the indoor navigation into the mobile devices more efficient.

Machine Understanding of Maps and Optimal Trajectory Calculation
Kršák, Pavol ; Burian, František (referee) ; Chromý, Adam (advisor)
The teasis deals with the creation of software tools, which use human element to extracts data necessary for navigation in the field of raster maps for orienteering. To achieve this goal, it is important to segment individual sections of the map according to symbols on the map. These symbols are illustrated on the map with one colour or combinations of colours, which create patterns. Because of identification of individual symbols, the work deals with segmentation according to colours and pattern matching. To navigate in the field is important information on height differences on the ground , for this reason the work discusses the position of contour identification and determination of their heights. Combining terrain data with data about height differences will create a 3D color models in XNA. To navigate in such a terrain that is used A* algorithm , in which the test several heuristic model defined distance. The A* algorithm then provides the optimum route according to specified criteria .The resulting application conveys the necessary tools to analyze raster maps orienteering , these tools are the manual and the automatic nature. The work includes detailed operating instructions of developed application.
