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.

Machine vision for robotic manufacturing systems
Honkyš, Pavel ; Bražina, Jakub (referee) ; Vetiška, Jan (advisor)
The Master's thesis deals with the use of a camera system in automated industrial applications and the use of TwinCAT Vision tools for image processing and control software PLC, which works on an industrial computer from BECKHOFF. The theoretical part deals with the algorithm of the camera system design for the industrial environment, the description of the individual components that create this camera system and the industrial buses used to transmit data from the cameras. The practical part contains the assignment, its analysis and design of a robotic workplace using a camera system to control products. The designed camera system is then assembled, programmed and verified for the functionality of the created algorithms and the designed HMI.

Development of a universal cell for optical part inspection in a robotic workplace
Cahlík, Radim ; Rajchl, Matej (referee) ; Adámek, Roman (advisor)
Cílem této diplomové práce je vývoj univerzální buňky pro optickou kontrolu včetně softwaru pro detekci vad, který používá metody umělé inteligence. Dalším cílem je integrovat buňku do robotického pracoviště a otestovat ji na rozdílných dílech s různými vadami. První část práce popisuje vývoj konceptu optické buňky a její návrh. Poté pojednává o systému pro optickou kontrolu, počínaje popisem objektivu a kamery a konče analýzou kontrolního softwaru, který pro detekci vad využívá konvoluční neuronovou síť. Další část se zabývá vývojem robotického pracoviště včetně návrhu dvojosého robota a komunikace mezi zařízeními. Nakonec je rozebráno testování na dvou rozdílných dílech s cílem ověřit funkčnost.

Machine Vision: Support for Lab Applications
Starý, Vojtěch ; Holoubek, Tomáš (referee) ; Matoušek, Radomil (advisor)
This diploma thesis deals with machine vision problematics and its use for laboratory applications. Machine vision is basically the substitution of human vision for machines using a video camera and a computer. The essence of this thesis is a brief review of machine vision and the issues associated with machine vision systems and brief description of hardware, software and algorithms used for this work. Implementation of machine vision on Raspberry Pi and Cognex platform. Connection of the Raspberry Pi platform with a parent platform (automaton, robot) and subsequent evaluation of the solution.

Counting of characteristic scales of sand lizards in colour images
Maršala, Štěpán ; Štursa, Dominik (referee) ; Škrabánek, Pavel (advisor)
The diploma thesis describes the design and implementation of a program for counting secondary scales in the image data of the ventral sides of the bodies of sand lizards. The program respects the requirements of scientists from the Institute of Vertebrate Biology of the Czech Academy of Sciences and the Faculty of Education at Masaryk University for the controllability and accuracy of results. The program consists of several parts. In input receives photos of sand lizards, in which he cuts out an area of interest. Unifies the orientation of these sections using detected objects. Object detection is provided by YOLOv4. Another part of the program called the Centroid Detector determines the position of the centers of the secondary scales in the unified sections. This part uses the U-Net convolutional neural network, which is specially modified to detect the centers of objects in close proximity. The other parts of the program divide the detected positions of the scale centers into left and right secondary rows and write their numbers to the output file.

Design and implementation of the robotic platform for an experimental laboratory task
Juříček, Martin ; Matoušek, Radomil (referee) ; Parák, Roman (advisor)
Pokročilá robotika se nemusí vždy pouze pojit s Průmyslem 4.0, nýbrž nachází své uplatnění i kupříkladu v konceptu Smart Hospital. Pokrok v této oblasti umocnilo onemocnění koronaviru (COVID-19), přičemž každé ulehčení práce zdravotnímu personálu je vítáno. V rámci této diplomové práce byla navrhnuta a implementována experimentální robotická platforma s hlavní funkcí stěru vzorků z předsíně dutiny nosní. Robotická platforma představuje kompletní integraci softwaru a hardwaru, kde má operátor přístup k webově založené aplikaci a může ovládat řadu funkcí. Opomenout nelze také zvýšenou bezpečnost a kolaborativní přístup. Výsledkem práce je funkční prototyp robotické platformy, který je možné dále rozšiřovat například v podobě použití alternativních technologií, rozšíření bezpečnosti či klinického testování a studie.

Machine vision for robot guidance
Grepl, Pavel ; Szabari, Mikuláš (referee) ; Vetiška, Jan (advisor)
Master's thesis deals with the design, assembly, and testing of a camera system for localization of randomly placed and oriented objects on a conveyor belt with the purpose of guiding a robot on those objects. The theoretical part is focused on research in individual components making a camera system and on the field of 2D and 3D localization of objects. The practical part consists of two possible arrangements of the camera system, solution of the chosen arrangement, creating testing images, programming the algorithm for image processing, creating HMI, and testing the complete system.

Design of station for PCV filter inspection
Tecl, Michal ; Huzlík, Rostislav (referee) ; Pavlík, Jan (advisor)
Bachelor thesis deals with the design of a station for automatic visual inspection of the PCV valve filter. The PCV valve is part of the Common rail system, which is discussed in detail in the research part. Furthermore, the principle and capabilities of machine vision are described. In the practical part, several design variants are developed, which are further evaluated. Based on this evaluation, the most suitable variant is selected and then elaborated in detail.
