The use of optical methods in the diagnosis of electrical machines
Tobolák, Petr ; Kuchyňková, Hana (referee) ; Janda, Marcel (advisor)
This term describes questions of scanning rotors of asynchronous motors using 3D scanner. At the beginning it deals with a theory of asynchronous motors, defects of these machines and last but not least also questions of 3D scanning. Directly it focuses on a practical processing of measured rotors and their necessary modifications using of a program GEOMAGIC. It includes a diagnostic of deviations of scanning components of rotors with a model created on a program AUTODESK INVENTOR and posiible reasons of their creation.

Environment mapping
Mohorko, Martin ; Pavlík, Jan (referee) ; Bilík, Martin (advisor)
This bachelor thesis deals with the description of possible ways of mapping the unknown environment, which could be in this case both environments - aerial and terrestrial. It is focused on mapping by radars and 3D scanners, through their history, distribution, scanning methods, methods of displaying data or description of output data to their practical application. Furthermore based on selected criteria, methods were compared and it was explained why and which method is preferable than the other one. There is also in this work mention of other methods used for environment mapping of today and their use and potential for several future applications. In the conclusion was outlined the possible use concept on the radar locating system in connection with the 3D scanner.

Structural analysis of part of electrical machine
Fodor, Viktor ; Hájek, Vítězslav (referee) ; Janda, Marcel (advisor)
This thesis discusses the optical diagnostics of electrical motor parts using a 3D scanner. It describes the construction of electrical induction motors, their heat losses, cooling and refrigeration systems that may be used by such motors. It approaches the possibilities of heat recording and briefly explains the 3D scanner’s principal. It also introduces the simulation program ANSYS which uses the finite element method. This thesis shows the post processing of the digitalized object and the simulations and compares the simulation and measurement results. The final part is devoted to the analysis of the obtained results.

3D data
Klusáček, Jan ; Janáková, Ilona (referee) ; Richter, Miloslav (advisor)
The goal of this thesis is to design methods for acquisition of three dimensional model of object using illumination by laser streak which is read by camera. The first part describes theoretical principle and points out some problems which are linked to this method. Followed by description of interfaces which can be used for acquisition of image from camera. Next part is focused on more detailed description of DirectShow interface which is used in this thesis. Description of concrete methods designated for processing acquired image, calibration and composition of three dimensional model are also topics of this work. The Last part describes device which was created to verificate and automatize designed methods.

3D scanner for educational purposes
Romanovský, Jiří ; Navrátil, Robert (referee) ; Koutecký, Tomáš (advisor)
This diploma thesis deals with the design of a 3D optical scanner using the structured light projection method. The aim of this thesis is to demonstrate the principles and processes of 3D scanning by using the DLP LightCrafter projector and the ImagingSource camera. The individual stages of the measurement process will be implemented to the Matlab software environment to describe the various principles and methods which can be used for digitizing the objects.

Optical Proximity Sensor with Time-of-Flight Measuring Principle
Mlatecová, Hana ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
3D optical proximity scanner is described in this thesis. The sensor is marked as 03D201 and is made by Ifm electronic, GmbH company. The text also describes the basic characteristics, measuring principle, PC connection method and communication. A program for communication between PC and sensor was created and named O3D_Application. This program provides functions for real-time data transfer and visualization. Measured data can be saved easily by this program. The thesis also contains an analysis of measured data and parasitic parameters of the sensor.

The utilization of reverse engineering in computation of vehicle aerodynamics
Rozsíval, Jan ; Forman, Matěj (referee) ; Porteš, Petr (advisor)
The vehicle body was measured by using ATOS 3D scanner. Measured data from the ATOS 3D scanner were applied to make a 3D model of vehicle body and to make a 3D model of whole vehicle by using computer program Pro/ENGINEER. The model of vehicle was made with a view for future use of CAD model. Surface of the vehicle model was used for computation of vehicle aerodynamics – aerodynamic static pressure distribution by using CFD software Star-CCM+.

A car prototype manufacture using modern methods and CAD/CAM
Horák, Aleš ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
The project developed under the engineering studies, solves the problem of production of a prototype car using modern technology, reverse engineering and CAD / CAM. Based on the literary study of the issue, was designed process of digitization of the physical model of car, including the treatment and processing of data. Follow-up step was to verify the production of the additive rapid prototyping technology - FDM method. Verification of the results was performed on a vertical milling cantilever FV 25 CNC with control system Heidenhain iTNC 530 using a cutting strategies by PowerMILL CAM software. At the end of the resulting models edit as necessary.
