Measurement of basic parameters of gas filters
Medek, Pavel ; Havránek, Zdeněk (referee) ; Bejček, Ludvík (advisor)
This master’s thesis deals with establishment of parameters of the PPI filter material using methods of image analysis. The first part is aimed at general methods used in practice, an overview of splitting into filter clasification and characterization of the PPI filter material. The second part represents an introduction to problems of machine vision. There are outlined basic methods of image processing. Last parts of the thesis study the method using detection of bright light levels. The measurement and interpretation of results is performed with the PPI material - types 10/6 and 10/12. For image processing is used the MATLAB program, version 7.0.1.

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.

Project of automated product control on production line
Pelcl, Milan ; Starý, Jiří (referee) ; Špinka, Jiří (advisor)
This work deals with analysis one of the production lines at ModusLink Czech Republic s.r.o. It seeks to find possibilities for automation of different processes on the line, currently performed manually. The basic focus is to find the appropriate technical solutions to the automated control of the designated production line. The work seeks to describe all meaningful solutions and compare their advantages and disadvantages. From this comparison of the final proposal is based on comprehensive solutions with the use of machine vision. Another point is the selection of a suitable contractor for the implementation of the proposal, making its advantage in economic terms and the resulting recommendations, if implemented the proposal.

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.

Design of control production unit with product dimension verification
Janoušek, Roman ; Tůma, Zdeněk (referee) ; Houška, Pavel (advisor)
This thesis solves the issue of design of control system for production line with machine vision to obtain the position and size of products. Part of the line is a digital camera, a delta robot and pneumatic manipulators. The introduction outlines the objectives of the thesis, followed by a discussion of sorting lines, including an example of a sorting line in practice. The main part of the thesis lies in the analysis and solution of problems relating to the machine vision and its use on the production line as well as its integration into the control system. The result of this work is a control system for management of the line and functional positioning and dimensions checking of the product passing through the production line. The conclusion of the thesis reviews the outcomes of the thesis.

Automation and Quality
Hebler, Violeta ; Toul, Jiří (referee) ; Fiala, Alois (advisor)
The topic of this bachelor thesis is quality control in the production process and means of improving the quality of products. It contains a description of methods of inspecting the production process, and the benefits of measurement automation and its practical use in the production process. The work also discusses the fundamentals and potential of machine vision use in various production areas and during the quality control process, starting with the receipt of material and ending with the shipment of finalized products.

Object Tracking Using Kalman Filter
Sehnoutka, M.
The goal of this paper is to describe design and implementation of system which is supposed to track objects in video sequence. Kalman filter is used for modeling object movement and prediction of its trajectory in moments when the object is hidden. System can use two different models. One is supposed to track objects that are moving with constant velocity and second one with constant acceleration.
