Integration of image data into a multilayer elevation map of the environment in real-time
Dobrovolný, Lukáš ; Dobossy, Barnabás (referee) ; Adámek, Roman (advisor)
This diploma thesis focuses on the optical calibration of RGB cameras, thermal cameras, as well as the mutual calibration of RGB cameras with LiDAR. For a thermal camera calibration, a special pattern that can be detected in the IR spectrum of the camera is required. In this thesis, we describe a tool we developed for calibrating this sensor. To verify the RGB camera calibration methods and its mutual calibration with LiDAR, we employ a robotic simulator as well as Matlab which provides the necessary tools. With the knowledge of the relative position of the camera and LiDAR, we are able to merge the data together. This method is then tested both in a simulator and with actual sensors. In the final part of the thesis, the image data is integrated into an elevation map.

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

IR camera data processing
Malík, Dalibor ; Petyovský, Petr (referee) ; Richter, Miloslav (advisor)
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.

Emisivity and its Impact on the Heat Conductivity
Gančev, Jan ; Hejátková, Edita (referee) ; Szendiuch, Ivan (advisor)
This work deals with the issue of emissivity and its impact on the heat dissipation.The first part describes the basics of thermal management, the issue of emissivity and its measurement. In the second, experimental part, are dedicated the emissivity values of examined specimens. These values are then used as initial conditions for the thermal simulation. In the last part are compared the measured results and the simulated results and is evaluated the impact of emissivity for the heat dissipation.

QFN Packages Soldering and Technology Procedures
Jakub, Miroslav ; Brno, Petr Martinec, HONEYWELL (referee) ; Starý, Jiří (advisor)
This master´s thesis deals with QFN packages soldering and technology procedures optimization. The aim of theoretical part is description of QFN packages, their assembly and reflow soldering on PCB in HONEYWELL. The aim of the practical part is to propose a method of measuring temperature and optimizing the thermal profiles of selected PCB with QFN packages by using convection (HONEYWELL) and infrared (BUT) reflow ovens. Comparison and evaluation of thermal profiles for 3 production PCBś with QFN packages using solder paste AIM NC257-2 were realised. The main part of master´s thesis are appearance evaluation of solder joints, preparing microsection and measuring intermetallic layers thickness by using the optical and the scanning electron microscopes, analysation and study of QFN defects created during soldering proces. These tests were performed with 2 production PCB´s. Optimization of SPI and soldering technology procedures where were analyzed QFN packages were processed on one type of PCB. Interesting part of this diplomma thesis is creating of the 3D heat transfer model of QFN package during the reflow soldering in SolidWorks.

Camera for biological applications
Jurák, Petr ; Slovák, Jiří (referee) ; Kubíček, Michal (advisor)
This diploma thesis is focused on the design of IP blocks for thermal camera. This termal camera is intended for plant research. The main part of the thermal camera is an infrared detector that detects a frequency in the range of 8 – 14 m. The analogue signal obtained is modified and subsequently digitized. The detector also includes a Peltier device which is designed for both detector cooling and heating, and is controlled by an external signal. The MicroZed development board implements IP blocks. The thermal camera is designed to be controlled from the MicroZed board. Device analysis is first described from the theoretical part to the design of IP blocks.
