Machine vision implementation for control of parallel mechanism
Zábrša, Tomáš ; Kovář, Jiří (referee) ; Andrš, Ondřej (advisor)
The topic of this bachelor thesis covers issues of parallel robotics. It is focused on challenges of one particular type of parallel robot – delta robot. In this thesis it is described history of parallel robotics, kinematical calculations and machine vision. In the last part of this thesis is description of practical programming of delta robot and palletisation task using machine vision. Parallel robots have, compared to serial robots, certain advantages, but also disadvantages. Parallel robots are more stable, lower mass and they have higher accelerations and can do more work cycles. Using machine vision they can be used for sorting tasks, for example to put product into crates or sorting of machine parts.

Lightweight Self-Steering Model Vehicle
Kubový, Matej ; Šimek, Václav (referee) ; Bidlo, Michal (advisor)
The main goal of this bachelor's thesis is to design and implement a model vehicle of reduced complexity with self-steering capabilities using commonly available components. The main part of the solution consists of a LEGO kit with the addition of the Raspberry Pi computing platform. The movement of the vehicle along the navigation line is ensured by the image processing from the built-in camera. It has been possible to create a system consisting of easily accessible and inexpensive components that can move autonomously in area. The result of this thesis is also a demonstration of the image processing and evaluation of experiments focused on functionality verification.

Machine vision for the check of moldings
Grepl, Pavel ; Pavlík, Jan (referee) ; Vetiška, Jan (advisor)
Bachelor's thesis deals with the design of arrangement of an automatic inspection unit for specified products using machine vision. The theoretical part is focused on specification of the inspection system and research in the area of machine vision components, such as cameras, lens and illumination. The practical part consists of multiple possible arrangements of the inspection unit. Solutions of the chosen arrangements, including programming and testing the application using Vision Assistant software. Finally, economic evaluation of the automation of the quality inspection using machine vision has been made.

Using machine vision for robot guidance
Gábik, Jaroslav ; Štěpánek, Vojtěch (referee) ; Vetiška, Jan (advisor)
With the development of machine vision technologies, new applications that can increase production, versatility or simplicity of production systems are widely spread. This thesis deals with usage of machine vision for robot guidance. The task consists of creating a technique and its practical realization, where the proposed assumptions are verified. The main objective is to determine 3D position and orientation of a sheet metal part or subassembly of the body-in-white, which is lying within the reach of an industrial robot with respect to its base coordinate system. The proposed method is suitable for several types and dimensions of components, which meet certain requirements. Targeting the component is carried out by scanning significant points on the component with the help of the 3D scanner attached to the robot flange. Afterwards, gained data are processed in a designed programme. The theoretical part is focused on research in the field of machine vision, accuracy of industrial robots, compensation of their errors and manipulation and assembly of the sheet metal parts in automotive. Finally, an evaluation and recommendations for practice are provided.

Neural Network Based Face Localization
Hendrych, Pavel ; Šiler, Ondřej (referee) ; Švub, Miroslav (advisor)
This thesis issues with possible methods for face detection and localization according to the state of the art. It describes various approaches and it is aimed at localization by neural networks and at necessary operations that have to be done before localization and after that for correct results representation. This project contains implementation of few approaches to neural netwok based face localization with emphasis on eigenfaces based face localization as well as implementation of simple classifier using distance of reconstructed face to the original one. Detailed description of implemented system, achieved results and dependecy of system performance on it's inner settings is also provided.

Design and implementation of control software libraries for fiber characterization
Podivín, Ladislav ; Hästbacka, David (referee) ; Kallio, Pasi (referee) ; Honzík, Petr (advisor)
Tato práce se zabývá návrhem a implementací dvou konkrétních softwarových modulů, které jsou částí distribuovaného řídícího systému CoSMic. Tento systém je určen pro řízení speciálního zařízení pro charakterizaci papírových vláken. Prvním vyvinutým modulem je HapticFiber, ten má poskytovat rozhraní mezi řídícím systémem a speciálním vstupním zařízením - haptic device. Druhým modulem je ViCo, jehož účelem je poskytnout softwarovou obálku pro uživatelem definovaný algoritmus zpracovaní obrazu. Tento modul musí být připraven splnit určitá časová omezení, proto je nutné, aby běžel v rámci operačním systému reálného času.
