Face mask visualization for a robotic head
Pospíchal, Tomáš ; Brablc, Martin (referee) ; Appel, Martin (advisor)
This bachelor thesis deals with face exposure visualisation using backward projection. Image calibration is implemented for correction of distorsion and brightness change caused by curved projection plane. Identification of deformation is done by projected checkerboard patern . For deformation method of Moving Least Squares (MLS) is used. Test tool is designed and projector upgrade for shorther throw distance is implemented.

Design of a mobile projection device supporting the virtual reality environment
Šooš, Marek ; Blecha, Radim (referee) ; Tůma, Zdeněk (advisor)
This work deals with the analysis of the state and development of virtual reality and AR. In this work I described in detail the advantages and disadvantages of individual technologies, history, present state and trends in development these technologies. In addition to modelling components in a virtual environment, the current state of the art allows the assembly or disassembling of individual machinery as well as testing their functionality and mechanical properties, using special goggles and gloves. The basis for creating 3D images are special projectors, in one, two, or quadruple configurations. The aim of this bachelor thesis is to design a modular and flexible box for the projectors. The designed concept allows for different flexible arrangements of one, two or four projectors, while providing us with simple and accurate alignment.

IR camera data processing
Malík, Dalibor ; Petyovský, Petr (referee) ; Richter, Miloslav (advisor)
The aim of this master’s thesis is to give information about the thermo camera measurement with error minimization. The basic concepts of thermography are explained with an implementation of postprocesing technique which uses graphically modified thermogram back projected to the scene. This is closely related to the scene design, calibration of thermal camera with projector, image rectification, thermogram processing with highlighting of interesting information and implementation of control elements as the user interface. The results obtained are analyzed and re-evaluated.

Game Interface with Data Projector and Leap Motion
Tomeček, Adam ; Najman, Pavel (referee) ; Zahrádka, Jiří (advisor)
This thesis deals with creating of game interface for projector and palm motion sensor Leap Motion. It describes principles of projection mapping on objects and different types of projection mapping and its use. Practical part deals with designing game interface for Leap Motion and projector and designing of demonstration games. It also describes the procedure of testing created game interface and games programmatically and with users.

Design Proposal for the Switching Mechanism of a Tourist Car Headlamp
Škývara, Tomáš ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
The purpose of this thesis was to create proposal of mechanism for the tourist shutter, which could replace the original solution for projector currently used by Visteon-Autopal. The thesis was focused on background research of known solutions and proposal of new mechanism. The proposal was processed from mechanical site at first. All proposals were created to get inspiration before final design of tourist shutter for projector.

Game Interface with Data Projector and Leap Motion
Kendra, Matej ; Beran, Vítězslav (referee) ; Najman, Pavel (advisor)
This thesis describes various game interfaces for human and gradually there are shown more modern and common available interfaces. Work closely describes how you can play games on a regular projector and sensors for gestures detection - Kinect and Leap Motion. This work focus on evaluation of aspects of table-game design with these components and also on display view calibration between projector and Leap Motion. Part of the project is devoted to describing the board game Catan, of which rules are taken to write down specification and options of player. According to this knowledge is then described the design of the play-set and the design of several interfaces of the game. Implementation is briefly described and final chapters covers forms of the testing methods of interfaces and testing evaluation from user perspective.

Structured-light 3D scanner
Hadzima, Jaroslav ; Chromý, Adam (referee) ; Jelínek, Aleš (advisor)
3D scanner is a device capable of creating a model using analysis, most commonly from image data. 3D scanners could be divided into two major groups, contact and noncontact scanners. Aim of this study is to interpret problematics of 3D scanning with structured light. Specifically usage of Gray code patterns. There is step by step evaluation of individual hardware and software obstacles and possible errors, from calibration to final point cloud. In next section, there are included tests determining quality, precision and accuracy of scanning with given method. System is applicable to mobile robots and yet fully remotely controlled. The majority of enumerations is taking place in Raspberry Pi 3 model B, just visualization alone is done from computer.

Realization of a structured light 3D scanner
Přikryl, Matouš ; Brablc, Martin (referee) ; Adámek, Roman (advisor)
The beginning of the thesis presents 3D scanner types. Following part describes how the structured light 3D scanners works. It takes into the account whole scanning process and adress problems like calibration, optical triangulation, or surface reconstruction of 3D objects. The second half of the thesis is focused on the implementation of simple 3D scanner, using Machatronics laboratory hardware. It also describes scanners behaviour in different conditions.

High resolution digital light source design for automotive industry
Machač, Petr ; Rubeš, Ondřej (referee) ; Věchet, Stanislav (advisor)
Digital high definition light sources are a new way of communication between car and other road users. By intelligent switching of high beam or projection of various warning or information symbols on the road a lot of even tragic traffic accidents can be prevented. The purpose of this thesis is to explore contemporary automotive lighting technologies, then to choose the appropriate technology for high definition light source and design a prototype of mechatronic lighting systém.

Board Games on Interactive Table
Svoboda, Petr ; Najman, Pavel (referee) ; Beran, Vítězslav (advisor)
This thesis focuses on the application of the tangible user interface and spatial augmented reality principals for playing board games. For this purpose, a system called interactive table was developed. It is both hardware and software solution. The hardware part solves the installation of a depth camera and a projector located above the table. The software solution deals with calibration of the depth camera and projector system using known procedures for camera calibration on the one hand, on the other hand it solves tasks from the field of computer vision. This perceptional part is the core of the whole thesis and for the purposes of playing board games it provides information about the location of the physical game object, physical game board and the calculations of mask for masking distracting objects. An educational application was developed for the purposes of demonstration of the system options. The interactive table offers new possibilities for playing board games in a real-world environment by the combination of the augmented reality elements with real-world objects and the related new user experience.
