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.

Contactless measurement of operational deflection shape
Tomek, Tomáš ; Klusáček, Stanislav (referee) ; Beneš, Petr (advisor)
This bachelor's thesis provides an overview of 2D/3D laser scanners used in measuring operating deflection shapes. Describes the issue of measuring the operating deflection shapes and modal analysis. My work also contains a description of the measurement chain. From the contactless measurement of a vibrating surface using the application created in LabVIEW to its visualization in Pulse Reflex.

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.

Reconstruction of Human Hand Surface for the Purpose of Biometric Recognition of Persons
Svoboda, Jan ; Drahanský, Martin (referee) ; Dluhoš, Ondřej (advisor)
The goal of this work is to create a device and design an algorithm for the recostruction of human hand surface for the purpose of biometric recognition of persons. First of all existing approaches to human hand surface reconstruction are introduced. Subsequently the theoretical base of the methods used in the solution is shown. Also, the device con- struction is presented in more detail to the reader. After that the reconstruction algorithm implementation is described. In the end, experiments and results are presented.

Self-localization and Navigation of Small Mobile Robot
Plucnar, Libor ; Florián, Tomáš (referee) ; Žalud, Luděk (advisor)
The thesis is focused on design of self-location and navigation of small mobile robot inside buildings. It contents a description of collecting and processing data from laser scanner and their application for wall following algorithms. Designed algorithm was tested on real mobile robot. It describes system of visual tags and algorithms for their detection and decoding. Visual tags are used for indication of checkpoints used for navigation of mobile robot. It also describes method for route planning between this checkpoints.

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.

Možnosti využití stolního stacionárního laserového skeneru pro dokumentaci movitých artefaktů
SEDLÁK, Michael
The thesis tries to point out to opportunity of using of stationary three-dimensional laser scanner documentation with regard to standards of conventional documentary methods. It provides a brief recherché and describes the issue of three-dimensional scanning. The limits of digitalization are observed by laser scanning application on the set of movable artefacts depending on the materials and morphology of objects. Part of this thesis describes comparison between this method and other possible documentation methods.
