Automated classification cell
Lahoda, Vlastimil ; Chromý, Adam (referee) ; Burian, František (advisor)
To optimize production at Tyco Electronics Czech s.r.o. I designed and implemented an automated classification cell with a collaborative manipulator Universal Robots UR5e and a Cognex camera system. The classification cell is supposed to pick up the loose parts and then optically test them, sorting the parts into output binders following the inspection results. First of all, I had to learn programming language for Universal Robots manipulators and Cognex vision system. Next step was to design and draw an electrical diagram. According to the diagram, I connected the cabinet and other peripherals. I also programmed an algorithm controlling the manipulator arm and inspecting of both cameras. Finally, I successfully tested the functionality of the entire classification cell.

Control integrated system for workpiece recognition
Vostřel, Tomáš ; Blaha, Petr (referee) ; Pivoňka, Petr (advisor)
The diploma thesis deals with the usage of integrated machine vision by B&R, Smart Sensor, for metal rectangular-shaped workpiece recognition and position determinition. The description of the usage of machine vision in the industry is made, the solution concept is created and the program and the user visualisation implemented. The main outcome of this work is the VITemplate library which can be used in combination with the model-based Blob analysis implemented in Smart Sensor to control the robotic arm to successfully grab all the workpieces on the belt.

Harris corner detector
Květný, Michal ; Martišek, Dalibor (referee) ; Procházková, Jana (advisor)
This bachelor’s thesis deals with application of Harris corner detector for finding corner points in images and models. This thesis also contains an implementation of the algorithms in Python programming language. Programs are tested on real images captured by camera and models created by 3D scanning.

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 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.

Analýza spadu na podložky na dně včelího úlu
CHLUBNA, Marek
This bachelor's thesis is dealing with methods of computer vision and use of convolutional neural networks for the purpose of detection and counting the Varroa destructor on the pad removed from the bottom of the beehive. A research of such methods and convolutional neural networks is done together with an implementation. Experiments are performed and the results are made with the vision of using the results of this thesis for creating a mobile phone application.

VC5 and Vision Designer platform visual system
Popovský, Pavel ; Janáková, Ilona (referee) ; Honec, Peter (advisor)
For the purpose of an future machine vision system development in Tyco Electronics Czech s.r.o. I have developed Cognex Designer template. Template will serve as a flexible basis for further development of camera applications on the Cognex VC5 industrial computer. The functionality of the program template has been successfully verified by modifying it to a particular application of the laboratory manual station used to measure the parameters of the manufactured connectors. A camera with lens and lightning was chosen and installed on the station. DIO communication was put into operation between VC5 and PLC system. The application has been calibrated and verified as a measurement system using MSA Type I and Capability study standard methods.
