Machine vision for product inspection
Strach, Petr ; Bražina, Jakub (referee) ; Vetiška, Jan (advisor)
The diploma thesis deals with machine vision in connection with robotic production systems. The theoretical part deals with machine vision hardware, principles and characteristics of machine vision, typical tasks in connection with machine vision, robot guidance using a camera, logical tasks for image processing in the TwinCAT program. The practical part focuses on the design of a robotic workplace with a camera to control the rotation of the part. This workplace was first put into operation virtually and then tested at a real workplace.

Diagnostics and Maintenance Design
Černoch, Adam ; Pohanka, Martin (referee) ; Kudrna, Jan (advisor)
In the text is given entry of visual inspection about implementation of the selected section in city of Luhačovice. Into forms were plotted failures of the road, determinated their lenght and surfaces. The following describes the evaluation and the cause of failure. After that is given the design and repair of the road. In the theoretical part is written the classification of failures according to TP 82 „Catalogue of flexible pavement failures“. From the cataloque I chose and mentioned important failures that are manifested in diagnosis section. Finally, describes the principles of planning and design of maintenance or repair.

Buildings monitoring
Kopuletá, Jitka ; Žítt, Petr (referee) ; Schmid, Pavel (advisor)
The bachelor thesis is aimed at the passportization of the breakdowns and imperfections on the front facades of houses on Arne Nováka and Gorkého streets in Brno where the reconstruction of the area of Philosophical Faculty of the Masaryk University will be in progress. The first visual inspection was accomplished before the beginning of the construction works. On its base the monitoring sheets of the separate buildings have been compiled.

Design of an Internal Methodology for MSA of Attributive Data in the Company
Jaroš, David ; Maradová, Karla (referee) ; Sámelová, Vendula (advisor)
This diploma thesis deals with the design of an internal methodology for MSA of attributive data in the company following a finding in the IATF 16949:2016 audit. The thesis text aims to map the current trends in approaches to attributional MSA analysis with a focus on visual inspection. Based on the theoretical findings, a new company methodology is to be subsequently proposed. The defined aims of this thesis were fulfilled, resulting in a methodology that meets the company's requirements as well as the methods described in the relevant manuals. The proposed methodology uses the cross-tab method, which describes the analysis of attributional data without knowledge of the reference. The result of the analysis are kappa coefficients, which determine the measure of agreement in the evaluation, and efficiency values of the measurement system. By following the principles described in this thesis, it is possible to generalize the proposed methodology for use in other companies.

Visual inspection of transparent products
Matus, Gabriel ; Horák, Karel (referee) ; Honec, Peter (advisor)
This project deals with the optical control of welding glass blank. The blank consists two small parts of made of special glass. This blank is an essential part of the measuring device density of oxygen. Measuring device algorithm is based on paramagnetic properties of oxygen. It is a small and precise piece of the whole mechanism therefore the precision and perfection made strict criteria. For checking compliance with those criteria, developed a computer program written in C# programming language. Its task is to rule on perfection produced parts. It also serves to back up data on individual production units.

Easily Configurable Visual Inspection System for Industrial Applications
Andrla, Ondřej ; Špaňhel, Jakub (referee) ; Španěl, Michal (advisor)
The aim of this thesis is to create a prototype of an easily configurable camera system, used to control products on an automated assembly line. The thesis is especially focused on the issue of LED detection. Their very presence in the image is detected and the system also evaluates whether the LED is lit and, if so, in what color. The final solution allows the user to easily define control metric for searching for circular objects in the image in a configuration application with a graphical user interface. The configuration is saved in a JSON file. Furthermore, a runtime which independently processes the recording from the camera, checks the products and reports on them to other components of the system based on the configuration was implemented. The system uses the Hough circular transformation to detect objects in the image. To test the efficiency of the system, a dataset was created using the FitKit tool with a LED matrix. When testing the runtime on the dataset, the overall accuracy of LED detection was 97,79%.

Design of Cordless Inspection Camera
Kuchárik, Martin ; Rubínová, Dana (referee) ; Sládek, Josef (advisor)
The aim of the bachelor’s thesis is the design of a cordless inspection camera, intended to inspect hard-to-reach places. The basis was to design a clean shape with elements of the minimalist design. Both the control and the usage shall lead to simplicity and intuitiveness. The result is a borescope with a camera with four LED lights, a wireless detachable monitor and a rechargeable battery. The purpose is primarily for plumbers, repairmen and also for handymen.

Diagnostics and Maintenance Design
Schindler, Marek ; Pohanka, Martin (referee) ; Kudrna, Jan (advisor)
Failures of the roads are an integral part of the use and aging infrastructure. Before proposing their maintenance and repair is necessary to make the diagnosis of the road. Technical specifications of TP 82 and TP 87 describe the correct execution of diagnostic methods, their methods of evaluation and suggested repair of pavements. In the Bachelor's work I am making the diagnosis of asphalt, with the subsequent proposal for repairs on the road III/4301 in the village of Nechvalín. All measurements, evaluation, design, repair and photo documentation is included in this work.
