Estimation of the Point Radiation Source Activity Based on the Airborne Spectrometry
Jurečka, Tomáš ; Chromý, Adam (referee) ; Lázna, Tomáš (advisor)
The thesis deals with the localization of gamma-ray source and an estimation of its radiation activity with airborne spectrometry. In the theoretical parts are presented the types of ionizing radiation, the principles of measurement of gamma-ray by scintillation detectors and the explanation of airborne spectrometry. A revision of algorithms for data processing from aviation spectrometry was performed. In the practical part, the sensitivity of scintillation counter was determined depending on the height above the calibrated source. The mathematical methods for locating and estimating activity of the searched emitter were verified.

High-Resolution Multispectral 3D Scanning and its Medical Applications
Chromý, Adam ; Duchoň,, František (referee) ; Mazal, Jan (referee) ; Žalud, Luděk (advisor)
Termovizní zobrazování i 3D skenování jsou v současné době rychle se rozvíjející technologie. Obě technologie mají mnoho výhod, které by mohly být užitečné v medicíně. Jejich datová fúze přináší ještě více nových diagnostických informací, než kdyby byly použity samostatně. Cílem této práce je vývoj multispektrálního 3D skenovacího systému založeného na novém způsobu snímání pomocí robotického manipulátoru vybaveného laserovým snímačem, teplotní kamerou a barevnou kamerou. Navržené řešení přináší jak flexibilitu, tak přesnost. Tento systém skenování je dále využit v klinických aplikacích, aby byly ověřeny jeho schopnosti a ukázány přínosy nad rámec současného stavu techniky.

Industry 4.0 planner
Kubásek, Martin ; Chromý, Adam (referee) ; Burian, František (advisor)
This thesis deals with the design of manufacturing planner for Industry 4.0 testbed. Before design the terms Industry 4.0, MES, ERP are explained. Then the problems concerning this testbed are explained and a possible solution is shown. This solution was supplied as part of the assignment. Planner was made around this solution and its structure and algorithms were shown. Planner is written as a C# application, which generates manufacturing plan from MES input data. This input data is downloaded through REST connection, output is saved to a JSON file. Finally, the results of this planner are shown as a report in xlsx table. The planner can successfully generate a manufacturing plan for Industry 4.0 testbed.

Automated classification cell
Lahoda, Vlastimil ; Chromý, Adam (referee) ; Burian, František (advisor)
To optimize production at Tyco Electronics Czech s.r.o. I designed and implemented an automated classification cell with a collaborative manipulator Universal Robots UR5e and a Cognex camera system. The classification cell is supposed to pick up the loose parts and then optically test them, sorting the parts into output binders following the inspection results. First of all, I had to learn programming language for Universal Robots manipulators and Cognex vision system. Next step was to design and draw an electrical diagram. According to the diagram, I connected the cabinet and other peripherals. I also programmed an algorithm controlling the manipulator arm and inspecting of both cameras. Finally, I successfully tested the functionality of the entire classification cell.

Localization and Navigation of Tello Unmanned Aircraft
Panský, Michal ; Chromý, Adam (referee) ; Gábrlík, Petr (advisor)
This bachelor thesis deals with the design of a suitable solution to control the unmanned aircraft Ryze Tello for use in autonomous missions. Its content is to familiarize and test all available SDKs and all the features they offer. Introduction to the location and navigation of robots in indoor spaces. Then there is described ROS and its implementation for the problem using the available SDK with instructions for installation and launch of the practical part. At the end of the work are displayed data obtained during the unmanned aircraft flight and the structure of the communication system, a description of the problems encountered during testing and a discussion of possible extension to this solution.

Automated measurements of body temperature against COVID-19
Roman, Matej ; Lázna, Tomáš (referee) ; Chromý, Adam (advisor)
This thesis focuses on the development of an open source software capable of automatic face detection in an image captured by a thermal camera, followed by a temperature measuring. This software is supposed to aid in the COVID-19 pandemics. The developed software is independent of used thermal camera. In this thesis, I am using TIM400 thermal camera. The implementation of the face detection was achieved by an OpenCV module. The methods tested were Template Matching, Eigen Faces, and Cascade Classifier. The last-mentioned had the best results, hence was used in the final version of the software. Cascade Classifier is looking for the eyes and their surrounding area in the image, allowing the software to subsequently measure the temperature on the surface of one's forehead. One can therefore be wearing a face mask or a respirator safely. The temperature measuring works in real time and the software is able to capture several people at once. It then keeps a record of the temperature of each measured individual as well as the time of the measurement. The software as a whole is a part of an installation file compatible with the Windows operating system. The functionality of this software was tested – the video recordings are included in this thesis.

Color correction of 3D model based on scene knowledge and light illumination
Dočkal, Michal ; Kopečný, Lukáš (referee) ; Chromý, Adam (advisor)
This thesis focus is on the design and verification of improvements for the RoScan robotic system texture module. RoScan is a robotic scanner for scanning and diagnosing the human body. In this thesis current texturing module of this system is described. Furthermore this thesis describes the theory of light, color and shading in computer graphics. Subsequently, improvments for RoScan texture module are proposed based on the said principles. The last part deals with the implementation of the test script in Matlab and the verification of the functionality of the proposed solution.

Optimization of 3D surface model merging from computational time perspective
Regec, Martin ; Burian, František (referee) ; Chromý, Adam (advisor)
The point of the work is connecting of partial 3D models of surface, which are overlapped in a certain area to a final whole model. The intention of the work is creation of algorithm that is fast enough and reliable enough to connecting partial 3D models and that can become a part of application RoScan Analyzer. In the introduction of the practical part of the work, we sum up problems of the work that we are keeping on. In the next part, the solution and implementation are suggested. In the last part, the outcome of the algorithm is veryfied. Implementation is written in Microsoft .NET Standard.
