The advantages and disadvantages of particular solutions and their effect on spread will be analysed as well. A system for spacing monitoring is chosen and constructed from them.
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%.

Ochrana soukromí a osobních údajů zaměstnanců ve vybraném závodu
Heinzová, Alena
HEINZOVÁ, Alena. Protection of the Privacy and Personal Data of Employees in a Chosen Factory. Diploma Thesis. Brno, 2018. Mendel University Brno. This diploma thesis focuses on the protection of the privacy and personal data of employees in a chosen factory. This has been necessitated mainly by a new legislation, namely, 'the General Data Protection Regulation'. The thesis is divided into three main parts. The first part focuses on literary research and provides a basic overview of important concepts of legislation, as well as an explanation of the concept of personal data and their structure. It further explains who the individual subjects of data protection are, who is the control authority. The second part consists of personal work, which examines whether the enterprise complies with legislative requirements in individual areas as well as preparing for the new European legislation in force. The next section discusses the company's shortcomings, which the company should pay attention to and there are also proposed some measures.
Reconstruction of Facial Images Using Neural Networks
Zubalík, Petr ; Drahanský, Martin (referee) ; Goldmann, Tomáš (advisor)
The main purpose of this bachelor's thesis is to propose and implement a model, using neural networks, that will be able to reconstruct low-resolution facial images with blurry parts of the face. The task of super-resolution of facial images is solved by two models based on convolutional neural networks. The first model is built upon the architecture of ResNet whereas the other model makes use of the principles of generative adversarial networks. The proposed models are implemented in the Python programming language with the use of application programming interface of the TensorFlow framework. Moreover, as a part of this work, an application with a simple grafical user interface was created. This application makes it easy to use the implemented models. Several experiments are analyzed in the last chapter of this thesis to evaluate the performance of the models.
Ovality measurement of extruded fiber using three cameras
Loučka, Pavel ; Martišek, Dalibor (referee) ; Štarha, Pavel (advisor)
One of the important parameters observed during extruded fibre fabrication is its diameter. The diameter can be measured with a single scanning camera assuming that the fibre section has a circular shape. As proved in practice, another important parameter is ovality, that is the rate of fibre flattening. This paper assumes that the fibre section shape is elliptical. In such a case, at least three different views on examined fibre are needed. Mathematical part of this paper is concerned with analytical description of fibre ovality measurement using two different approaches based on the knowledge of linear algebra, projective geometry and conic sections theory. Main goal of this paper is thus to use both mathematical theory and image analysis methods for ovality and diameter determination. Precise calcluation of such quantities is, however, conditioned on precise camera system calibration, which is described in the paper as well. Additionally, the work contains a brief mention of technical realization of ovality measurement and its possible difficulties.
Camera system in the workplace and its encroachment on personal rights of employees
Průšová, Aneta ; Morávek, Jakub (advisor) ; Štefko, Martin (referee)
The topic of this thesis is the legal regulation of camera system in the workplace and characterization of its encroachment on personal rights of employees. The main emphasis is put on conditions, which employer must fulfil to install a camera system in the workplace in compliance with the legal order of Czech Republic. Furthermore this thesis is devoted to issues of discreet surveillance and of defence of employee options in case of illegal monitoring. This thesis is divided into three following chapters. In the first chapter, technological development of video camera and its components as well its gradual using as surveillance equipment in public space and afterwards in private life of persons are described. This chapter deals with today's situation and number of video cameras in society, not only in Czech Republic but also in the whole world. Increasing amount of video cameras represents as its consequence a reason for legal disputes, especially neighborhood's legal disputes. Considering that mentioned fact, the relevant decisions of the Supreme Court illustrating attitude of judicature to camera surveillance are incorporated in the first chapter. The thesis' core is set in the second chapter, which is focused on concrete conditions of installation of camera monitoring in the workplace and their...
Physical Security in an Industrial Company
Konečný, Pavel ; Ondrák, Viktor (referee) ; Sedlák, Petr (advisor)
The diploma thesis focuses on physical security solutions in an organization acting in a metallurgy segment. The analytical part identifies the weaknesses in individual areas of physical security according to ČSN/ISO 27 000 regulation. The practical part is divided into individual chapters bringing suggestions for corrections, modernization and modifications of the system. The theoretical part deals mainly with clarification of the terminology and proceses used in the practical part. I see the benefit of my work in the practical suggestions for the changes. If they are implemented correctly, the physical security of the organization will be of high quality.
