Drone position stabilization methods using image data
Koukal, Ondřej ; Raichl, Petr (referee) ; Janoušek, Jiří (advisor)
This bachelor’s thesis focuses on the design of an unmanned aircraft stabilization system. The purpose of this system is to determine the exact position of the unmanned aircraft in space based on image data from two cameras in real time. The theoretical part describes the image processing methods and the algorithm for determining the position of the unmanned aircraft. The practical part describes the implementation and testing of the system.
Testing the Effect of Flight and Scan Strip Alignment Parameters on the Accuracy of the Point Cloud Obtained by the DJI Zenmuse L1 Lidar System
Boušek, Martin
This paper deals with testing the effect of flight and scan strip alignment parameters on the accuracy of the point cloud obtained by the UAV-mounted DJI Zenmuse L1 lidar system. The flight parameters tested are the scanning mode, the cross-strip overlap size, and the flight speed. The strips were aligned in the TerraMatch software by using the vector tying features and the ICP algorithm. The accuracy of the aligned point clouds was determined by comparison with a triangular terrain model obtained by photogrammetry.
Design of quadcopter contol sytem with visual guidance
Pokorný, Ondřej ; Věchet, Stanislav (referee) ; Andrš, Ondřej (advisor)
Tato práce pojednává o návrhu a implementaci systému řízení kvadrokoptéry s vizuálním naváděním k vytištěné značce. Systém se skládá výhradně z komerčně dostupného hardwaru a open source nebo uživatelského softwaru. Jednotkami jsou například mikropočítač Raspberry Pi 3 Model B, mikrokontrolér Arduino Nano, letový kontrolér Omnibus F3 atd. V první části je nastíněna struktura navrhnutého systému a popsány vlastnosti a funkce jednotlivých komponent. Následuje přehled použitých druhů komunikací a jejich verzí specifických pro létající platformy. Nakonec je popsána architektura uživatelského softwaru společně s fungováním jednotlivých částí a důvody pro jejich přítomnost v kódu. Druhá část se zaměřuje na použití knihovny pro augmentovanou realitu ArUco za účelem odhadování polohy, dále se zaměřuje na opatření zavedená pro kompenzaci nedostatků spjatých s použitím tohoto systému. Tato část také obsahuje popis vývoje řídícího algoritmu a následného testování implementovaného řešení. Na závěr jsou navženy možné další kroky ve vývoji.
Usage of UAV in geophysical survey – the overview
Hlůšek, Josef ; Houfek, Martin (referee) ; Krejsa, Jiří (advisor)
This bacheor´s thesis elaborates on possibilites of use of unmanned aerial vehicles (UAVs) in geophysical surveys. The thesis introduces a list of methods and sensors used in geophysical surveys, an owerview of commercially available UAVs suitable for such survey followed by analysis of their capabilites.
The design of control unit for UAV robot.
Arnošt, Petr ; Marada, Tomáš (referee) ; Věchet, Stanislav (advisor)
This diploma thesis is focused on the design of the control software for the unmanned aerial vehicle. Parrot Ar.Drone quadrocopter was a representative of the unmanned aerial vehicle. This thesis describes the way of control and communication with the unmanned aerial vehicle. Based of this information the flight control software for Ar.Drone quadrocopter is created.
Video Synthesizer
Richtr, Pavel ; Cenek, Filip (referee) ; Krekovič, Slavomír (advisor)
Generating a video signal for ATtiny85 , authoring software worldwide for video game console ATARI2600 on the theme of UAV attacks and their media image - a reinterpretation of using "low res" generated video.
Contemporary UAS and the possibilities of their application to European commercial space
Matejko, Filip ; Šplíchal, Miroslav (referee) ; Vosecký, Slavomír (advisor)
The work contains a brief overview of some modern unmanned aerial systems and later their capabilities of integration into controlled airspace in Europe. It discusses the current legislation dealing with different areas of integration of UAS and the update and developing process of legislation. Another section deals with the exploration of the possibilities of using unmanned aircraft in the commercial sector and their impact on the existing air transportation. The last section is devoted to the technical aspects associated with the integration of UAS into controlled areas. It describes the current systems of the CNS and their possible development in conjunction with UAVs and also a significant part of the work is devoted to the technology of the S&A (Sense and Avoid). During the entire work is gradually evaluate the current situation of the operation of UAS and are designed and recommended necessary changes that will need to be perform to their successful integration into the controlled airspace.
Modelling and simulation of communication system receiver for unmanned aircraft
Hoferek, Jakub ; Prokeš, Aleš (referee) ; Maršálek, Roman (advisor)
This paper deals with the modeling of receiver properties for the transfer of command information for unmanned airplanes.
Summary of Unmanned Aerial Vehicle
Haman, Tomáš ; Navrátil, Jan (referee) ; Dofek, Ivan (advisor)
The bachelor’s thesis deals with summary of unmanned aircraft. There is a reference to their historical development and possible uses for the selected aircraft are their technical parameters, including pictures. Thesis contains several types of UAV division according to various criteria. From these categories was selected a few representatives, which is followed by each of them a few characteristic data. The last part is a comparison of several aircrafts between two close categories.
Conceptual design of competition model with vertical take-off and landing
Monková, Paulína ; Grim, Robert (referee) ; Hájek, Tomáš (advisor)
The bachelor thesis deals with the conceptual design of the competitive model of the aircraft for the international design student competition held in 2022. The introduction of the work focuses on the analysis of the rules of competition. The research section focuses on possible aircraft configurations and existing commercially available models of the same category as the competition rules. The practical part of the work processes the selection and closer characteristics of the individual parts of the aircraft, the mass analysis process and the determination of the aerodynamic centre of the model. The output of the work is a conceptual design and system model.
