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.

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 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.

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.

Machine vision for locating objects
Hasík, Dávid ; Huzlík, Rostislav (referee) ; Vetiška, Jan (advisor)
The bachelor’s thesis deals with design of machine vision system for object localization and its application possibilities. Design approach, its components and their individual advantages and disadvantages for this type of machine vision system are described. This thesis also includes simple model of machine vision system for object localization using regular PC. For image processing is used Vision Assistant and its tools. Two scripts are made in this software and their performance is compared.

Design of LED lighting for industrial camera systems
Svoboda, Martin ; Honec, Peter (referee) ; Janáková, Ilona (advisor)
The bachelor thesis deals with the development, design and construction of multispectral lighting for industrial camera systems. The lighting is conceived as a modular device consisting of two parts - a control unit, which can be communicated primarily through the Modbus TCP / IP protocol, which powers, controls and collects information about the connected lighting unit. The illumination unit is equipped with 64 intelligent RGBW light emitting diodes located in an 8x8 matrix and one control diode opposite to which light intensity sensors are placed to give feedback on the color and intensity of the light. There are two temperature sensors located between the LEDs to check the temperature of the lighting unit. Both units are housed in a robust aluminum chassis. The control unit contains a microcomputer programmed in C language

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.

Lightweight Self-Steering Model Vehicle
Kubový, Matej ; Šimek, Václav (referee) ; Bidlo, Michal (advisor)
The main goal of this bachelor's thesis is to design and implement a model vehicle of reduced complexity with self-steering capabilities using commonly available components. The main part of the solution consists of a LEGO kit with the addition of the Raspberry Pi computing platform. The movement of the vehicle along the navigation line is ensured by the image processing from the built-in camera. It has been possible to create a system consisting of easily accessible and inexpensive components that can move autonomously in area. The result of this thesis is also a demonstration of the image processing and evaluation of experiments focused on functionality verification.

Machine vision for the check of moldings
Grepl, Pavel ; Pavlík, Jan (referee) ; Vetiška, Jan (advisor)
Bachelor's thesis deals with the design of arrangement of an automatic inspection unit for specified products using machine vision. The theoretical part is focused on specification of the inspection system and research in the area of machine vision components, such as cameras, lens and illumination. The practical part consists of multiple possible arrangements of the inspection unit. Solutions of the chosen arrangements, including programming and testing the application using Vision Assistant software. Finally, economic evaluation of the automation of the quality inspection using machine vision has been made.
