The thesis deals with the detection of thermal bridges of the building envelope of SCHOTT s.r.o. and MANNTECO s.r.o. The aim of this diploma thesis is the experimental verification of thermal defects and anomalies of peripheral structures of buildings. The qualitative infrared thermography method is used to ensure the results. The results of the experimental measurement revealed thermal defects and anomalies on the peripheral shells of the measured objects. The acquired thermograms are evaluated. With regard to the measurement results, construction operations are proposed, which are suitable for the elimination of thermal defects and anomalies of the building envelope.

In this thesis is dealed the technical term diagnostic with Fluke Ti55 thermo imager. In the introduction of description is analyzed noncontact temperature measurement including principle, uncertainties measurement and measurement system. In other parts of the work is focused on thermal imaging, termogram, description Fluke Ti55 termo imager and measurement of mechanical stress. The concluding part of the description and processing of measurements, including their evaluation.

The aim of the thesis is to clarify the issue of non-contact surface temperature measurement with a focus on the thermal imaging cameras as a modern representative of pyrometers and thermovision technology used in the output control of power supply. To obtain the corresponding results of temperature control, it is necessary to know the exact values of emissivity of the measured materials. The experimental part of this thesis is focused on detection of emissivity of power supply parts.

This work deals with non-contact measurement of surface temperatures. The aim of the first part is to explain basic terms, principles and ways of measuring temperature. Furthermore, there is an overview of thermal imagining cameras usable in industry. In the practical part there is a theoretically suggested experiment, which monitors the dependence of the surface temperature on the size of the cross-section of the workpiece during the turning under unchanged cutting conditions. Experimental measurements are executed with using thermocamera ThermaCAM SC 200 and they are evaluated in software called Researcher.

This dissertation is focused on the research of the applicability of the thermographic method in the diagnosis of concrete bridges in the Czech Republic. The theoretical part characterizes selected defects of concrete structures and the principle of their detection. The practical part describes the measurements made in the laboratory on the test specimen and the field on the concrete bridge. Most attention is paid to infrared thermography, ground-penetrating radar and ultrasonic pulse-echo method. Based on the results of the dissertation, recommendations for the use of the thermographic test method in practice were developed.

The aim of this master’s thesis is to give information about the thermo camera measurement with error minimization. The basic concepts of thermography are explained with an implementation of postprocesing technique which uses graphically modified thermogram back projected to the scene. This is closely related to the scene design, calibration of thermal camera with projector, image rectification, thermogram processing with highlighting of interesting information and implementation of control elements as the user interface. The results obtained are analyzed and re-evaluated.

This paper deals with non-contact measurement of temperature in human faces. Principle of measurement of infrared radiation and construction of the thermal imager is described in a literature search. The main part of the paper is design of an algorithm for automatic processing and the detection of regions of interest in thermal images. The theoretical description of used methods is also included in this paper. The aim is to design and implement a program for automatic evaluation of temperature changes in a human face in a sequence of thermal images that were taken with short time delay. As a part of thesis is description of implementation of designed algorithm in programming enviroment MATLAB and the description of the user interface. The program was tested on the experimental data samples. Obtained results and possible limitations are also discused in this paper.

This thesis is concerned with thermodiagnostics in industrial practise, which is very important for the assessment of technical condition of object on the basis of temperature, in today's time. It includes summary of contact and contact-free methods and their principle, advantages and disadvantages for aplication in industrial practise. Because of thesis it was carried out measurement in company Daikin Device Czech republic with the use of contact thermometer and two available thermocameras for solving of topical tasks relating to production.
