CAD design of the Walther PPS M2 laser sight housing
Macků, Veronika ; Hejtmánek, Petr (referee) ; Vančura, Jan (advisor)
The aim of this thesis is to create a housing for a laser-sight for a Walther PPS M2 pistol with the aid of reverse engineering methods. The first part is a research about laser-sights. The second part contains contemplation about the problem, mainly the restrictions brought on by the design of the Walther pistol and of the energy source of laser-sight Streamlight TLR-6, as well as the chosen production method of the housing, which is 3D printing. The main part describes the acquirement of input data via scanning the body of the Walther pistol and the housing of TLR-6, the making of the CAD design of the housing, the printing of a prototype with a 3D printer and the consequent correction of the CAD model on the basis of analysis of the prototype.

Measurement and evaluation of the inserts using an optical scanner
Vanek, Richard ; Šrámek, Jan (referee) ; Marek, Tomáš (advisor)
This bachelor thesis focuses on problematics of scanning damaged press dies by an optical 3D scanner. The bachelor thesis starts with a description of 3D scanning, its use in various branches of industry as well as defects that can occur during scanning. This work provides an overview of the methods of 3D scanning and 3D scanners. Another part of the bachelor thesis deals with the procedure of scanning a damaged press die using the optical scanner STEINBICHLER COMET LED 5M followed by processing the acquired data and creating a 3D CAD model. In the final part, the bachelor thesis focuses on comparing and evaluating the obtained data.

Adaptive Planning of Industrial Robot Trajectory
Dizorzi, Matúš ; Burian, František (referee) ; Chromý, Adam (advisor)
This thesis deals with the extension of the RoScan scanning system features, making its behaviour more secure and adaptivte during scanning of the object on its whole trajectory. This work contains mathematical model of said manipulator, suggested methods to ensure proper behaviour during singularities. New features were added to the RoScan system such as control panel for manipulator control including new format of trajectory log, moving closer or further away from manipulator’s end effector and non adaptive trajectory testing for singularities. Result of this work is ready-to-use.

Temperature scanning with Web site presentation
Svoboda, Vít ; Vyoral, Josef (referee) ; Kacálek, Jan (advisor)
This master’s thesis solves design and realisation of device for temperature value scanning. First chapter introduces reader into basic principles of transmitting data over inetrnet. Next, the conception of whole designed system is described. Third chapter treats about suitable types of hardware to complete the system. Fourth and fifth chapter describes coherent vision of software realisation for values scanning and their storing into database. Last part attends to implement the dynamic web pages.

Creating a Depth Map of Eye Iris in Visible Spectrum
Kubíček, Martin ; Kanich, Ondřej (referee) ; Drahanský, Martin (advisor)
Diplomová práce si dává za cíl navrhnout a uvést v praxi metodiku snímání oční duhovky ve viditelném spektru. Klade přitom důraz na kvalitu snímků, věrohodné podání barev vůči reálnému podkladu a hlavně na kontinuální hloubku ostrosti, která odhaluje dosud nezk- oumané aspekty a detaily duhovky. V poslední řadě se také soustředí na co nejmenší vys- tavení duhovky fyzickému stresu. Metodika obsahuje přesné postupy jak snímat duhovku a zajištuje tím konzistentnost snímků. Tím umožní vytvářet databáze duhovek s ohledem na jejich vývoj v čase či jiném aspektu jako je například psychologický stav snímané os- oby. Na úvod je v práci představena anatomie lidského oka a zejména pak duhovky. Dále pak známé způsoby snímání duhovky. Následuje část, jež se zabývá správným osvětlením duhovky. To je nutné pro požadovanou úroveň kvality snímků zároveň ale vystavuje oko velkému fyzickému stresu. Je tedy nutné najít kompromis mezi těmito aspekty. Důležitý je popis samotné metodiky obsahující podrobný popis snímání. Dále se práce zabývá nutnými postprodukčními úpravami jako je například složení snímků s různou hloubkou ostrosti do jednoho kontinuálního snímku či aplikací filtrů pro odstranění vad na snímcích. Poslední část práce je rozdělena na zhodnocení výsledků a závěr, v němž se rozebírají možné rozšíření či úpravy metodiky tak, aby ji bylo možné použít i mimo laboratorní podmínky.

Braille Reader
Fabík, Jiří ; Svoboda, Pavel (referee) ; Maršík, Lukáš (advisor)
This thesis deals with image processing, specifically scanned Braille documents. It is about recognition of Braille cells, followed by transferring to plain text. Braille dots are recognized on the basis of bright and dark parts, which are created during scanning. After connection to the characters, they are converted to plain text by means of the character set. It also locates positions of possible errors to make it easier to correct the final text.

3D scanning methods
Čermák, Jan ; Matyáš, Pavel (referee) ; Marada, Tomáš (advisor)
In the first part of this thesis there is a task of taxonomy of the 3D scanners. It explains some principles of the 3D scanners functioning. Then in the second part there are described two particular technologies of the 3D scanning in the more complex way. In the chapters of both of these methods there is described procedure of scanning and compared several commercially available sensors. In the end there is comparison of these two methods.

Design of self-checkout
Baránek, Jan ; Rihák, Samuel (referee) ; Haltof, Vladimír (advisor)
The topic of this master’s thesis is design of a self Checkout. The thesis focuses on a new perspective on composition and shaping of the machine while respecting technical and ergonomic requirements. The main goal of this thesis is creation of an innovative appearence and incorporation of new technologies which will raise efficiency of the machine.
