Image data processing
Hamada, Adam ; Říha, Kamil (referee) ; Kubásek, Radek (advisor)
The main aim of this bachelor‘s thesis was the design of measure system and position detection method of one-shot plot in two axis system in cooperating with PROTOTYPA company. Also includes principle describe method which scanning fast moving object by high-speed CCD sensors. Further this thesis describing two algorithms for real-time process CCD video signal and in the end are selected components for this algorithms.
Measurements of the object position and velocity by using optical scanners
Uncajtik, Petr ; Říčný, Václav (referee) ; Kratochvíl, Tomáš (advisor)
The objective of Master’s Thesis is to research the utilization of line optical sensors for object location´s and speed measurement in cooperation with PROTOTYPA company. At the beginning of the Thesis there is an explanation of CCD sensor components and photodiods working principals. Further are discussed particular methods of object sensing. There are schematics of different sensor locations and flying object. The other step deals with introduction to the question of ray impact on sensor in the way of using different light sources and optical systems. In the other part of the Thesis are presented two sensors, which have been chosen by PROTOTYPA company workers. Final part of the Thesis deals with description of executed experimental measurement with LCCD 2048S-14 type of sensor. Experiments are aimed for statical and dynamical processes. In statical part was checked displaying of fixed objects on CCD sensor in internal spaces on the assumption that changing of object-lens focalization, object´s high and shape. For the evaluation was used of MATLAB program. Dynamical part of measurement is aimed for moving objects.
Testing of astronomical positioning system MAAS-1
Kremser, Christian ; Vondrák, Jiří (referee) ; Machotka, Radovan (advisor)
This thesis deals with testing of astronomical measurement system MAAS-1, which was developed at the Institute of Geodesy, Faculty of Civil Engineering, Brno University of Technology. Several reference measurements were done on the terrace of B building Faculty of Civil Engineering during this testing. The data obtained were processed into astronomical geographic coordinates and . These coordinates, as well as atmospheric conditions and calibration measurements, are basis for evaluation. In this test I try to detect the influence of the CCD sensor mounting of the accuracy on the final data and to assess if the construction needs to be modified.
Adaptable video A/D converter
Maňas, Stanislav ; Hála, Ondřej (referee) ; Říčný, Václav (advisor)
Master's Thesis deals with the complete proposal of light adaptability A/D converter. In the second chapter there are describes types of sensors. Third one describes the most used methods of light adaptability. In the fourth chapter there is describe the adaptability A/D conversion. Chapter 5 describes the block diagram. In the sixth chapter there is the design of all blocks of A/D converter. Finally in the chapter 7 there are construction documents for realization.
Optical spectrometer designing
Dohnal, Marek ; Křivák, Petr (referee) ; Hudcová, Lucie (advisor)
This project focuses the problems of projection and design of optical instruments being instrumental to determination of elements in various material compounds. There are described here the structures of fundamental optical instruments and their possible variants, one of which has been chosen and further entered into details. The work specifically refers to an optical spectrometer, which by its nature, ranges the bands both of visible and near-infrared radiation. The work presents basic principles of particular parts, which the existent instrument can consist of, the advantages and disadvantages brought by the single parts. For specifically proposed configuration, intentionally set in such a way it uses state-of-the art measurement methods obtaining the best possible measurement results, the work analyzes in details the method of operation and solves numerically the theoretical assumptions for correct operation of the spectrometer. A constituent of the project is an experimental measurement testifying, with certain errors, to the theoretical solutions. The measurement errors that could result from chosen arrangement and chosen measurement method are numerically expressed in a separate sub-chapter. Further various calibration methods are mentioned, based on which the calibration method used during the experimental measurement was selected. The last part of project is focused on circumferential design of the optical spectrometer, where series of suitable circumferential elements was scrutinized. For basic elements there are presented their parameters and possible troubles related to the implementation. Furthermore the realisation of project was carried out and the spectrometer was assembled with the parts available in laboratory. The results were elaborated with a computer programme created specially for this application and then compared to a professional spectrometer.
