Uncertainty of vehicle dimension measurement using 2D lidar
Želinský, David ; Richter, Miloslav (referee) ; Šedivá, Soňa (advisor)
This diploma thesis deals with the explanation of terms such as measurement error and uncertainty of measurement. It also introduces the term LiDAR, describes its construction, how it works and what it can be used for. The information from the theoretical part of this thesis is then used to analyze the uncertainties of measuring the dimensions of vehicles using 2D LiDAR. The individual measurement uncertainties are explained and calculated on an example. Furthermore, a LabVIEW program is created, which calculates the dimensions of the vehicle and the uncertainties of these dimensions from measured data. Finally, the results of the program are compared with real dimensions. The thesis is elaborated for the company Cross Zlín.

Road Detection for Autonomous Car
Komora, Matúš ; Veľas, Martin (referee) ; Španěl, Michal (advisor)
This thesis deals with detection of the road adjacent to an autonomous vehicle. The road is recognition is based on the Velodyne LiDAR laser radar data. An existing solution is used and extended by machine learning - a Support Vector Machine with online learning. The thesis evaluates the existing solution and the new one using a KITTI dataset. The reliability of the road recognition is then computed using F-measure.

Evaluation of defects and disturbances of an existing structures
Uher, Adam ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
The bachelor thesis describes the most used methods of diagnostics of building structures, then it focuses on the use in diagnostics of as yet unused modern technologies, potentially replacing several activities in the work of diagnostics and other professions. The advantages of these technologies, specifically 3D scanning, are presented on a case study of the revitalization of an apartment building in Brno, Koliště 33. In the practical part of thesis is described the process of diagnosis of defects and failures of the object, including applied methods and findings. The output of the work is a proposal of measures and a set of recommendations.

Fusion of drone sensors for motion planning
Semerád, Jakub ; Novotný, Josef (referee) ; Janoušek, Jiří (advisor)
This bachelor thesis deals with drone flight planning in an unknown environment. In order for a drone to be able to perceive its environment, it must be equipped with the necessary sensory equipment. This thesis discusses possible sensor equipment suitable for flight coordination and collision avoidance. Also, software for sensor data processing and drone motion planning are described and used here. LiDAR and depth camera were used for the experiment in this thesis. In the experiment the data from both sensors are fused together through ROS software and displayed in RViz simulation environment. This data are suitable for subsequent use in drone motion planning and collision avoidance.

Autonomous Rover Navigation on Planetary Surface
Vaško, Marek ; Prustoměrský, Milan (referee) ; Chudý, Peter (advisor)
Výskum hlbín vesmíru doviedol k vývoju technológii v rôznych oblastiach. Jednou z týchto oblastí je prieskum povrchu mimozemských planét. Efektívny spôsob skúmania je bezpilotné pozemné vozidlo. Práca sa zaoberá jedným z najdôležitejších systémov bezpilotných vozidiel, čím je autonómna navigácia. Vozidlo sa musí vedieť orientovať v priestore a zmapovať potenciálne prekážky. Práca v úvode preskúma navigačné princípy, ktoré boli využívané existujúcimi vozidlami. Neskôr preskúma využitie algoritmu na princípe súčasnej lokalizácie a mapovania a jeho implementáciu v MATLAB-e. Tento algoritmus bude integrovaný do simulátora, ktorý umožní neskoršiu integráciu do reálneho prostredia pomocou Robot Operating System. V simulátore bude navrhnutá platforma vozidla so simulovanými senzormi a šesť-kolesovým podvozkom, ktorá bude slúžiť na testovanie integrovaného algoritmu. V závere sa vyhodnotí kvalita navrhnutého algoritmu a zaháji sa diskusia o budúcich vylepšeniach.

Microwave radar sensor data processing focused on detecting the trajectory of people
Uher, Adam ; Slováček, Miroslav (referee) ; Valach, Soběslav (advisor)
This bachelor ‘s thesis deals with a topic of people detection and tracking their movement in regions of interest. The individual methods that can achieve people detection are analyzed. To implement people detection and tracking their movement microwave radar sensor IWR6843AoPEVM from Texas Instruments is chosen for this task. This hardware and its software are described in detail. Then simulation is conducted to track people in a queue and its results are evaluated. Different advantages and disadvantages of individual methods are compared with each other. Finally, there’s a summary of possible implementations for this device and target platform is chosen to verify its functionality.

Design of an active protection system LIDAR for the detection of subsonic missiles
Gedeon, Sebastián ; Vilém, Jan (referee) ; Antoš, Martin (advisor)
The diploma thesis focuses on the design of an Active protection system LiDAR, with emphasis on the research for the operation of these systems and the components of which the system consists. It specifies the basic optomechanical parameters that the designed system must achieve. The thesis introduces a conceptual design of an optical system for ground surveillance and aviation surveillance. LiDAR systems are made of off-axis or Cassegrain telescopes. As a part of this thesis are also designs of an optical illuminating system and a zoom lens for infrared imaging.
