Application of SLAM algorithms for 4WS vehicle
Najman, Jan ; Krejsa, Jiří (referee) ; Grepl, Robert (advisor)
This paper deals with the application of SLAM algorithms on experimental four wheel vehicle Car4. The first part shows the basic functioning of SLAM including a description of the extended Kalman filter, which is one of its main components. Then there is a brief list of software tools available to solve this problem in the environment of MATLAB and an overview of sensors used in this work. The second part presents methodology and results of the testing of individual sensors and their combinations to calculate odometry and scan the surrounding space. It also shows the process of applying SLAM algorithms on Car4 vehicle using the selected sensors and the results of testing of the entire system in practice.

Modernization of 3D measuring instrument
Janoušek, Pavel ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
The theme of this thesis is solving modernization of 3D measuring instrument. The modernization was necessary for implementation of new activities. Based on customer’s requirements, a new Incoming Inspection for the new projects was established. Another reason for modernization is development of new products. These new products require the most modernized measuring technology. There are presented 4 variants of solution.

Laser Projector
Svoboda, Pavel ; Burian, František (referee) ; Žalud, Luděk (advisor)
The aim of this thesis is to create a system, which draws the graphics with the help of a set laser project and eventually is able to synthetize several coloured rays and thus realise a multicolour drawing. The whole system is controlled by a Raspberry PI microcomputer and the data is sent to it from a PC via an Ethernet cable. The transmission of the projector device was identified and possible ways of improving the device were suggested. The results of this thesis allow creation of a multi-coloured vector picture, transferring it into the device and depiction on the project desktop. The whole device can therefore be used for example for the purpose of a presentation.

3D Scanning with Proximity Planar Scanner
Chromý, Adam ; Burian, František (referee) ; Žalud, Luděk (advisor)
Tato práce popisuje konstrukci skenovacího systému pro tvorbu trojrozměrných modelů. Kombinace laserového scanneru a robotického manipulátoru tvoří velice flexibilní zařízení schopné snímat jak velké, tak malé a detailní objekty. Zařízení nachází uplatnění v mnoha aplikacích, zejména v lékařství, kde přináší řadu nesporných výhod proti stávajícím systémům. Práce popisuje mechanickou konstrukci zařízení, funkční principy a jeho kalibrační proceduru. Součástí práce je i software pro vizualizaci naměřených dat a jejich zpracování do podoby modelů se stínovaným povrchem. Výsledkem práce je funkční zařízení a rozsáhlý obslužný software.

Laser proximity scanner - Electronics
Padyšák, Zdeněk ; Burian, František (referee) ; Žalud, Luděk (advisor)
In first chapter I introduce with aim of diploma work and in second chapter with principles distance measuring in robotic. After it in next chapter I describe used distance sensor, his principle and characteristics. In fourth chapter I describe control and parts mechanics shoulders. The fifth chapter describes program, which control mechanics shoulders by the 32bits microcontroller Freescale. At last sixth chapter gained data are modified and resulting imagery in 2D and in 3D.

Review of methods to determining wear in hip replacements
Zapletal, Jakub ; Vrbka, Martin (referee) ; Ranuša, Matúš (advisor)
This bachelor thesis analysis issues of observation and measurement of wear on hip replacements. First of all there is a description of historical milestones in development of hip prosthesis. Afterwards there is a recherché study of measuring methods and devices, whereas each one of them is reviewed for pros and cons. In the last section these methods are compared and there is an author’s recommendation for the most viable method for observation and measurement of wear on hip prosthesis.

Comparison of methods of 3D model
Balák, Martin ; Bartoněk, Dalibor (referee) ; Hanzl, Vlastimil (advisor)
This bachelor thesis is about 3D modelling by using different methods and different types of processing. It describes the process of creating a model in Photomodeler software and Autodesk 123D – Catch software. A major part of the thesis focuses on comparing accuracy of the photogrammetric evaluation. Another factor used to compare the different techniques is how time – consuming it is. The final chapter is devoted to the overall evaluation of the techniques.
