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.

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.

Accuracy of non-contacting Temperature Measurement
Horák, Ladislav ; Janečka, Jan (referee) ; Vdoleček, František (advisor)
This master’s thesis is specialized on the influence of correct parameters of emissivity, which depends on the temperature, wavelength and ambient environment. The investigation the parameter was taken infrared non-contact thermometer MI3 from company Raytek. To improve the quality of measurement was designed and programmed measuring utility program. The program was developed in the LabView 8.5 programming environment. To obtain the true value of the measured temperature of the target was designed and constructed the touch thermometer with the resistance dependent sensor. The thermometer is connected to the communication box of infrared thermometer and contain the same program. Nowadays are the most advanced IR thermometer with fixed parameters emissivity, which is applicable just to the real body in the vicinity of the parameter emissivity 0,95. For those IR thermometers were designed correction function, which would have temperature measured at a fixed emissivity parameter 0,95 set close to the actual value of the object.

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.

Increasing the Yield of BGA Repair Process
Janíček, Martin ; Vala, Radek (referee) ; Řihák, Pavel (advisor)
This thesis deals with possibilities of increasing the yield of BGA repair process. First there is mentioned basic problematics and its notions, problems and possibilities. Next it deals with technological aspects of repairing of devices in BGA covers. Also there is mentioned basic problematics of evaluating of yield. There is stated current state of solving the problem and also there is suggested new design of application which would be more optimal for evaluation of the yield of process. This thesis contains results of practical testing of methods of application of flux affecting final quality of solder joints as well as kind of flux which was used. At the end

Control Unit for Autonomous Vacuum Cleaner
Matějů, Jan ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
This paper is in introduction focused on review of robotic vacuum cleaning and evaluation of available products qualities. However the main focus of this paper is system design of all subsystems, control systems and PCD design of robot electronics. In this paper is also described a method for evaluating approximate distance of robot from the obstacle. There are also described problems of system design of IR proximity sensors. The last part of this work is development of control software for robot and its testing.

Workstation with termo camera
Zeman, Martin ; Horák, Karel (referee) ; Richter, Miloslav (advisor)
This thesis contains an overview of physical principles concerning thermography and infra-red sensing, and a specification of a measuring instrument in a measurement system. Next, there are some particular examples of IR sensing applications. In the second part there is a thermal camera market research including individual manufacturers and models with their attributes and prices. There is a closer view of the thermal camera used for this thesis (Guide EasIR-4). In the end of the thesis there are some drafts of computer vision subject tasks (or practices), including workplace designs and solutions, and three task suggestions for bachelor or diploma theses including solution verifications.

Použití klasického digitálního fotoaparátu pro fotografii v blízkém IR záření
Hošek, Jan
The goal of the presented work was to use the standard CCD photographic camera for visualization of near IR spectral source. Almost every standard CCD camera chip is usually sensitive not only in visible spectral range but the maximum of spectral sensitometric characteristics of CCD chip is around wavelength 800 nm. In order to be possible take snapshots with standard CCD photographic camera without color distortion caused by near IR illumination the sensitivity of the camera chip is artificially decreased.
