Multispectral Map Building in Mobile Robotics
Burian, František ; Mazal,, Jan (referee) ; Zemčík, Pavel (referee) ; Žalud, Luděk (advisor)
The dissertation deals with utilisation of multispectral optical measurement for data fusion that may be used for visual telepresence and indoor/outdoor mapping by heterogeneous mobile robotic system. Optical proximity sensors, thermal imagers, and tricolour cameras are used for the fusion. The described algorithms are optimised to work in real-time and implemented on CASSANDRA robotic system made by our robotic research group.

The use of thermovision technology in output control of power supplies
Rejžek, Jan ; Slaný, Martin (referee) ; Polzer, Aleš (advisor)
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.

A fuse heating measurement using IR camera
Belák, Michal ; Valenta, Jiří (referee) ; Aubrecht, Vladimír (advisor)
Bachelor's thesis deals with various principles of contactless temperature measuring and comparison of these principles. Different kinds of detectors, which are used in pyrometers and thermovision systems are presented, together with description of various kinds of the contactless thermometers, their division according to many different criteria. Next it is intended on the description of thermovision exploitation in different areas of practice. An example of practical fuse heating measuring and its analysis is also presented.

Contactless measurement of surface temperatures when machining
Šťáva, Radek ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
Contactless measuring of surface temperature integration in the other measurement methods and their assimilation at evaluation of surface temperature of a semi-finished product bored by various tools is the target of the work. An impassable opening is being bored by these tools. The opening is close to a scanned wall. The semi-finished wall temperatures are being scanned by thermocamera and subsequently compared for every single used tool in this experiment.

Contactless measurement of surface temperatures during milling
Kmenta, Michal ; Slaný, Martin (referee) ; Polzer, Aleš (advisor)
This Master's theses deals with the contactless measurement of surface temperatures and incorporates it among other methods of temperature measurement. For practical experiments were used infrared camera ThermaCAM SC 2000 from producer FLIR. The experiment was focused on the area of manufacturing technology – milling. Have been investigated effects of different cutting conditions on the surface temperature of the machined sample and the results are expressed mainly in the charts.

Application of IR imaginery in electrical engineering
Strmeň, Milan ; Valenta, Jiří (referee) ; Aubrecht, Vladimír (advisor)
This work deals with contactless measurement of a temperature, its principles and types. Above all, it is aimed mainly on thermovision. Infrared camera SH-68 / HY-6800 is presented and its functions are described. Brief instruction manual together with important information on a measurement is also presented. An example of a simple measurement, which is itemized to several steps, is worked up in the framework of the project. The last part of the project is devoted to the thermovision applications in a general practice. Temperature rise of a part of high voltage diconnector was measured by IR camera and compared to the contact method of the temperature measurement.

PID Analysis of Photovoltaic Power Plants in Czech Republic
Hamr, Tomáš ; Strachala, Dávid (referee) ; Hylský, Josef (advisor)
This Bachelor´s Work summarizes basic knowledge about construction technology of solution of photovoltaic equipment. solution which suffers from degradation by influence of potential. There are described possible restriction solutions of potential induced degradation which takes effect at the level of FV system, FV modul and FV cell. The work contains diagnostics of photovoltaic power station using thermovision measuring and U/I analysis with following assessment of a problem. Futhermore, the cooperation will continue with companies NWT and Sunfin where possible futher measurement with analysis will take place and data analysis from solar power stations.

Engine Motormanagement Software
Kopecký, Ivo ; Vítek, Ondřej (referee) ; Hájek, Vítězslav (advisor)
Fuel injection is a means of metering fuel into an internal combustion engine. In modern automotive applications, fuel metering is one of several functions performed by an "engine management system". A fuel injection system is designed and calibrated specifically for the type(s) of fuel it will handle: gasoline (petrol), Autogas LPG (also known as propane), ethanol, methanol, methane (natural gas), hydrogen or diesel. The majority of fuel injection systems are for gasoline or diesel applications. With the advent of electronic fuel injection, the diesel and gasoline hardware has become quite similar. During the last twenty years a preparation of a fuel mixture and the way of ignition in engine segment have changed the most. Instead of a carburettor it is being used the unit, which prepare fuel mixture according to a status of a car on the road e.g. change of pressure, temperature or ratio of a fuel and air.

Contactless measurement of surface temperatures during turning
Merenda, Jiří ; Slaný, Martin (referee) ; Polzer, Aleš (advisor)
The goal of this thesis is the incorporation of the contactless measurement of surface temperature among other methods of temperature measurement. Technical preparation for experimental measuring on the machine-tool. Comparison of influence of cutting conditions on the development of surface temperature of workpiece during the machining process with usage of the camera ThermaCAM CS2000. The economical analysis of the contactless measurement of surface temperature is determined in the last part of this thesis.
