Automation of optical measuring via TRITOP optical coordinate system
Koutecký, Tomáš ; Růžička, Bronislav (referee) ; Volek, Aleš (advisor)
The goal of this diploma thesis is to automate photogrammetric measuring system TRITOP. In the literature retrieval part there is a review of digitizing methods and its description. Further it contains a description of the photogrammetric system TRITOP role. The practical part of the thesis deals with methodology of the TRITOP measurement and evaluation process automation. Automation is then verified on a practical example.

Program for light pattern decoding in structured light 3D scanner application
Ďuriš, Miroslav ; Zatočilová, Aneta (referee) ; Koutecký, Tomáš (advisor)
This thesis deals with decoding program design for fringe projection 3D scanner and transformation of decoded information into world coordinates. Contemporary indus-try increasingly uses the optical measuring devices to control dimensional and geo-metrical quality of produced products. Therefore, the main goal of the thesis is to expand existing knowledge about the optical 3D scanner used at the Institute of Ma-chine and Industrial Design at Faculty of Mechanical Engineering Brno University of Technology and to create software that handles images made by a camera, using lim-ited available information about the measuring system and its parameters. Fringes projected by a projector form a sinusoidal pattern, that is phase shifted several times to obtain a wrapped phase map of this pattern. Then the phase unwrapping is carried out using the multi-wavelength method. Relations between the unwrapped phase of a pixel and world coordinates are obtained by empirical system calibration. The thesis describes a complete process of the program development and its func-tionality. The data obtained from the developed program are compared with the data generated by original 3D scanner control software. Consequently, there is determined an accuracy and functionality of the developed program and algorithms.

Development of color filter wheel
Kilián, Ondřej ; Koutecký, Tomáš (referee) ; Hurník, Jakub (advisor)
This bachelor thesis aims to showcase designing process of the device and control software and subsequent realisation of a filter wheel for research applications, which is designed specifically for a ZWO ASI 1600MM camera, ZEISS Interlock® Compact lenses and optic filters produced by company Schneider-Kreuznach. This configuration of camera and lenses doesn’t allow use of existing products on the market.

Elaboration of examples for teaching assembly breakdowns in Inventor
Nečas, Zbyněk ; Koutecký, Tomáš (referee) ; Košťál, David (advisor)
This bachelor’s thesis deals with the presentation environment of the Autodesk Inventor program, especially the description of individual functions and how to work with them. The main part of this work is the creation of educational examples for teaching assembly breakdowns in Inventor. Because this is a new subject, there is only a limited number of these examples. Therefore, three educational presentations will be part of this work, describing the process of how students will work with the created assemblies available to them in E-learning. These examples will help students to gain knowledge and experience about decomposition of assemblies, following creation of images and videos, as well as their use in drawings or technical manuals.

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.

Comparison of certified and lowcost material for stereolithography 3D print
Sobota, Matej ; Zatočilová, Aneta (referee) ; Koutecký, Tomáš (advisor)
The aim of the bachelor’s thesis is to define basic quality parameters and compare material impact on quality of printed products. This is a comparison certified material with low-cost material using SLA-DLP method of 3D printing to reduce production costs. The thesis is focused on the comparison of two different materials based on the results of tensile and hardness tests. The effect of the color of photopolymer on material properties is also observed.
