Use of an automatic camera system for assembly quality control
Rajnštajn, Jakub ; Hejkrlík, Lukáš (referee) ; Zháňal, Lubor (advisor)
The presented thesis is focused on automation of the assembly quality inspection at the assembly hall M1 in Škoda Auto a.s., Mladá Boleslav. In the first part, the main elements of Industry 4.0 are mentioned, especially artificial intelligence and machine learning, then the project Direct Quality Feedback is introduced, which is a good example of Industry 4.0 in Škoda Auto. The next section shows selected camera-based inspections operating across industrial enterprises. Thereafter, individual locations within the assembly area on the M1 hall, that are potentially suitable for the installation of an automated inspections, are presented, with three of them selected for realization. First of them is wheels inspection, where the solution utilises both hardware and software made by the KEYENCE company. The second case is the inspection of door panels, where the evaluation logic and the individual parts to be inspected have been determined, but till the handover of this thesis, the project wasn’t finalised due to ongoing negotiations over investment and regular overhead costs funding. The last use case is the damper cover inspection, which was chosen to demonstrate a solution that will be easily transferable within the plant and adjustable to another inspection area in a short time frame. This has been implemented in two ways – the first uses Basler's Pylon vTolls software, the second uses MATLAB.

UV adhesive coating detection
Pavelka, Radek ; Richter, Miloslav (referee) ; Honec, Peter (advisor)
This diploma thesis focuses on a design of camera control system used for detecting defects, appearing during a UV luminescent glue application on the bottom of a paper bag. As a part of this thesis, an application was developed, using Baumer VCXG-53C industrial camera, implementing two dierent control methods - 2D cross correlation image pattern matching based on previously user defined pattern and glue area size measuring based on binary segmented image. The result of this work is a fully developed control system, prepared to be put into operation at the customer’s production line.
