Modern diagnostic methods use in defectoscopy
Vítámvás, Zdeněk ; Stránský, Lubomír (referee) ; Juliš, Martin (advisor)
Nowadays non-destructive testing offers various ways to detection defects in material. By selecting of suitable method or suitable combination of tests we can locate the defect and determine size of defect with sufficient accuracy. For higher probability of detect defects and for easier operation and evaluation are still evolve new ways of inspection. There are summarizes both ordinarily and modern methods using in defectoscopy in this work. There are describe its principles, courses of testing, suitability of use and there are drop next general information.

Innovation of the existing feeding device solution in the context of an automated and robotic workstation
Porubský, Radek ; Marek, Jiří (referee) ; Knoflíček, Radek (advisor)
This thesis deals with the design of a new version of the production and assembly node, which is part of an automated and robotized workstation for product assembly. The main objective of modifying the original solution is to eliminate the problems of the existing solution and apply innovations to make the work process of the equipment more efficient. The main modification of the original solution is the replacement of the bowl vibratory feeders in combination with linear vibratory feeders by a flexible feeding system with camera and robot. The paper describes the process of designing a new solution for the node, which eliminates the problems of the existing solution and at the same time comes up with new innovations. By solving the problems of the original solution and introducing the innovations, the reliability, speed and smoothness of the working process of the machine is improved. The work includes, among other things, drawings, risk analysis and costing.

Applications of Machine Learning in Predictive Maintenance of Industry 4.0
Navrátil, Tadeáš ; Richter, Miloslav (referee) ; Horák, Karel (advisor)
The thesis develops machine learning algorithms for use in the Industry 4.0 concept. The main focus is on predictive maintenance and visual inspection. In the theoretical part, the thesis focuses on a literature search of machine learning methods in the field of anomaly detection in time series and image data. The practical part deals with the reimplementation of the selected methods and their evaluation using the confusion matrix and metrics based on it

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.

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.

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.

Inspection of endangered cultural heritage assets in Iran
Drdácký, Miloš
Findings and comments based on visual inspection of damaged historical buildings – cultural heritage monuments - by Professor Miloš Drdácký. lt seems that there is a lack of an advanced documentation and especially diagnostics of condition of historical buildings and monuments. Namely, long term monitoring of defects in their relation to loadings is missing. Further, laboratories and know how for determination of material characteristics has a potential for improvement.

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.
