Determining of Dron Localization Using Navigation Systems
Nosál, Jan ; Goldmann, Tomáš (referee) ; Drahanský, Martin (advisor)
The thesis describes problems of drone navigation using navigation systems with which the navigation modules that have been tested are able to work. Next the issue with flight path and the determination of the incline and direction of the flight of the drones was solved also. Drones are more and more popular devices used for military, agricultural and commercial purposes. The thesis contains information about most used navigation systems which we encounter every day especially in cars and aircrafts. There were tested two navigation modules for drone localization. Modules capable of handling five navigation systems GPS, Glonass, Galileo, Beidou, QZSS and they can communicate with the Arduino board and IMU controller for drone positioning.

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.

Representation of the world in early maps
Jílková, Petra ; Bayer, Tomáš (advisor) ; Semotanová, Eva (referee)
Representation of the World in Early Maps Abstract The thesis deals with an analysis of the representation of the world in early small scale maps in the 16th - 18th centuries. The theoretical framework consists of the outline of the historical context of the given period with emphasis on the representation of the world in connection with the progress of the discoveries and the expansion of the geographical horizon. The development of navigation methods and technical means used to determine the latitude and longitude that had a direct impact on the positioning accuracy of topographic map elements are depicted, too. The practical part of the thesis is focused on the cartometric evaluation of selected map works of European cartographers of the period of 16th - 18th centuries, which consisted of the analysis of cartographic projection and the analysis of the positional accuracy of topographic content. The geometric accuracy of the maps is assessed mainly by the value of the positional deviations in the north-south and west-east directions. Based on the results of the cartometric evaluation, the evolution of the topographic content positioning is determined and the approximate time process of expanding the image of the known world on the contemporary maps is captured. The graphical outputs of the thesis are...

Vliv podmínek práce stroje na přesnost řízení jeho pohybu
Šlampa, Martin
This bachelor thesis on the topic of The impact of conditions of work of machine on ac-curacy of steering of its movement deals with the methods of allowing accurate positio-ning on the Earth. The thesis presents and describes the most common ways of positio-ning and its principles. Major part is focused on the influences, which cause a deteriora-tion of accuracy of determining the position of the working conditions of the machine. The end of the thesis is devoted to possibilities of use of the navigation in agriculture

Terrain passability analysis using machine understanding of maps
Pařík, David ; Jelínek, Aleš (referee) ; Chromý, Adam (advisor)
The diploma thesis deals with creation of computer aplication that can be used for conversion of raster maps for orienteering into model. Aplication will use this model to calculate optimal track between two selected locations. The thesis describes the development of a module for speed analysis in different types of terrain and another module for detection of roads and impassable objects. Thesis builds on work of Ing. Pavol Kršák and describes new features that were implemented to simplify user's control.

Internet of things and navigation applications
Kouba, Václav ; Luc, Ladislav (advisor) ; Veber, Jaromír (referee)
This bachelor thesis is focused on the internet of things and GPS navigation applications. The first part of the thesis consists of theoretical basics to familiarize the reader with the internet of things, its development, areas of use and security. Currently, built in navigation devices and navigation applications in smartphones are used separately, the internet of things is going to change that. In the second part todays GPS navigation applications are analyzed and compared based on the selected criteria and it is verified if the navigation applications for smartphones can replace the built in solution of BMW X5. The applications are compared based on their functions. The aim of this thesis is to analyze each of the selected applications and compare them based on the selected criteria and choose the best replacement for the built in solution until there are combined solutions available with synchronization between the built in navigation system and a navigation application.

3D Navigation for Mobile Robots
Škoda, Jan ; Barták, Roman (advisor) ; Obdržálek, David (referee)
We propose a novel 3D navigation system for autonomous vehicle path-planning. The system processes a point-cloud data from an rgb-d camera and creates a 3D occupancy grid with adaptable cell size. Occupied grid cells contain normal distribution characterizing the data measured in the area of the cell. The normal distributions are then used for cell classification, traversability and collision checking. The space of traversable cells is then used for path-planning. The ability to work in three-dimensional space allows the usage of autonomous robots in highly structured environments with multiple levels, uneven surface or various elevated and underground crossings. That is important for the usage of robots in real- world scenarios, in urban areas or for disaster rescue missions. Powered by TCPDF (www.tcpdf.org)

IVA Movement Quality Improvement for the Virtual Environment of Unreal Tournament 2004
Macháč, Bohuslav ; Gemrot, Jakub (advisor) ; Mráz, František (referee)
Title: IVA Movement Quality Improvement for the Virtual Environment of Unreal Tournament 2004 Author: Bohuslav Macháč Department / Institute: Department of Software and Computer Science Education Supervisor of the master thesis: Mgr. Jakub Gemrot, Department of Software and Computer Science Education Abstract: PogamutUT2004 is an extension of the Pogamut platform designed for developing intelligent virtual agents (IVAs) in Unreal Tournament 2004. Navigation of IVAs in Pogamut is handled by a navigation system, which uses a navigation graph as an environment abstraction. Navigation mesh is a new, more advanced abstraction, but the existing navigation system is not capable of using its advantages. We created a new navigation system, which exploits advantages of the navigation mesh and solves several other issues of the old one. We show that the new navigation system improves the quality of navigation. To demonstrate the quality improvement, an evaluation framework was created for the comparison of navigation systems. Systems were compared in terms of total number of significant paths on the map, which the system is able to follow, length of the path and time of the navigation. We selected 18 different maps for thorough evaluation and we performed the basic evaluation on 58 other maps. The new system is more...
