Non-contact temperature measurement
Sládek, Vojtěch ; Minář, Petr (referee) ; Hermanský, Dominik (advisor)
The aim of the thesis was the study of non-contact temperature measurement and the use of this measurement in the field of production machines. The first part of thesis includes concepts and definitions that are necessary for familiarization with the issue. In the second, practical part, contact and non-contact measurements were compared in two experiments. In the first one the machine frame was measured, on which the thermal load was simulated, the emission was determined, which was compared with emissivity from the tables. In the second experiment, the temperature gradient of the ball screw was measured during the ball screw operation and was determined emissivity, which was again compared with the table values. The conclusion of the thesis summarizes advantages and disadvantages of non-contact measurements that have been verified in practice.

Application of thermal camera for analysis of heat
Palička, David ; Pokorný, Jan (referee) ; Lízal, František (advisor)
Within this bachelor degree thesis I have focused on the thermal losses from storage tanks serving as asphalt binders. I have used the theory of non-contact temperature measurements using a thermovision camera. In the first part of this document I deal with the history, theory and some basic principles of non-contact temperature measurements. In the second part I am examining the thermovision camera settings. The third part considers the function of the asphalt mixture production plant itself, as well as the function of storage tanks. In the last part of this thesis I analyze the results of the measurements. The goal of this analysis is to compare results of thermal losses from storage tanks heated with thermal oil, and storage tanks heated with an electrical thermocouple.

Thermal Imaging System for Measuring Body Temperature
Mysza, Róbert ; Kolář, Dušan (referee) ; Goldmann, Tomáš (advisor)
The COVID-19 pandemic brought increased need for measuring human temperature. This thesis deals with solution of using low-cost thermal camera module FLIR Lepton 3.5 for measuring human forehead temperature and examines the real usability of this in terms of an accuracy. In the beginning, I describe various methods of measuring temperature and factors, which can influence the measurement. Subsequently, I examine various factors influencing human body and surface temperature. As of result of thesis is full design and implementation of thermal image system for temperature measurement, which I tested in different environmental conditions and compared its the precision against medical contactless infrared thermometer.

Recognition of Face Thermoscans
Váňa, Jan ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
Images of human face are one of the most used biometric features in automatic identification. This article presents an approach which uses face images in thermal (infrared) spectrum for purpose of important face features (eyes position, head rotation) detection and identification.

Environmentally Advanced Library
Burýšková, Jana ; Vyhlídalová, Karolína (referee) ; Horák, Petr (advisor)
The main aim of the Master‘s project is to design a library and a cafe in Příbram. The project is divided into three parts. The first part deals with architectural and structural design. The second with technical building services and the third with thermal imaging. The building has a basement and two above-ground floors. The building is founded on foundation strips. The building is designed with load-bearing brick walls and pre-stressed slabs Spiroll. The roof is a flat intensive green roof. The building envelope is insulated with mineral wool. In the building there is air a conditioning and a cooling system. As a heat source, a pressure-independent heat exchanger unit connected to the local hot water pipe will be used. A part of the electricity consumption is covered by photovoltaics. In the third part there are images from a thermal camera for some libraries. Imagines were evaluated if there are thermal bridges in the measured libraries. The project was carried out in the AutoCAD programme.

Jančuš, Rastislav ; Babinec, Tomáš (referee) ; Petyovský, Petr (advisor)
This half-yearly project includes basic briefing about thermovision technics and color models. Analyses functions and concepts for correct settings thermal camera on create images, which are included people. This work contains acquaintance with thermal camera EasIR-4, which was created database testing images, and with software Guide IrAnalyser shipped with this camera. The third part this project includes process about creating color models of skin and algorithm for identification people in thermal images, which emanate from human temperature and color skin. This algorithm is realized in program Matlab.

Detection and Classification of Military Targets in a Videosignal
Košík, Michal ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
The aim of this thesis is to design and implement algorithms for detection and classification of distant targets. The reader will become familiar with algorithms for detection of a movement, namely image difeerentiation and an algorithm based on a Bayes classifier. In the following two possible ways of classification, one using support vector machines and the second one utilizing a set of linear classifiers, will be introduced. At the end of this thesis results of the algorithms will be described and evaluated.

Možnosti využití bezpilotních prostředků při hodnocení efektivity zateplení budov zemědělského charakteru
Čubík, Josef
The bachelor thesis deals with the measurement of heat leakage in agricultural buildings. Depending on the dimensions of these buildings, it is necessary to consider how to improve the assessment of their heat losses. The most used technology for measuring heat leakage is by using handheld thermal cameras. Considering the large areas and the time required, it is suggested to use an unmanned vehicle with suitable characteristics for this task. However, the measurements were done using a thermal imaging camera, which led to selecting an area under which conditions it is more efficient to use a drone. The difference between internal and external temperatures is essential for a conclusive measurement. Therefore, sheds requiring higher temperatures designed for chicken fattening, were chosen for the experiment. The result showed that heat leakage is a significant problem. All the buildings investigated showed heat loss. The leakage varied depending on the specific type of hall measured and the insulation used. Losses were particularly evident in older buildings with leaks and exposed structural construction. Leakages were mainly in the form of significant thermal bridges.

Synchronous scene recording with multiple cameras
Ladický, Milan ; Vičar, Tomáš (referee) ; Kolář, Radim (advisor)
This thesis provides a detailed description of the basic equipment for synchronous capture from two cameras. The cameras used are thoroughly characterized, and the principles of their usage in scene capturing are explained. Furthermore, the theory of image fusion is examined, with a specific focus on fusing color and grayscale images from a thermal camera. The main emphasis is placed on the software framework, which is extensively described from camera initialization and image acquisition processes to storing captured images, fusion calibration, and the actual creation of the resulting fused image. The architecture of the application and its surface logic are outlined, along with a discussion of the key libraries utilized in the program and their significance for the entire process. This work establishes a stable software foundation for developing a program that enables synchronous capture and fusion of resulting images, thereby opening up new possibilities for image processing and analysis
