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.

Risks of the Road Transport And Their Factors
HEJKRLÍK, Lukáš
The bachelor thesis Risks of the Road Transport And Their Factors deals mainly with the risk of avenues that are planted along the Czech roads. I have focused on basic definitions that are closely connected to road transport and I have also focused on ex-planation of practical methods used when assessing traffic accidents in the theoretical part of the thesis. In the practical part of the thesis I have focused on concrete analyses related to existence of avenues along the Czech roads. These analyses confirm the de-gree of risk of road transport itself but especially fatal consequences of accidents caused by a crash with a fixed obstacle that is often presented by a tree from avenues along the roads. The analyses discovered that the accident rate in the Czech Republic is decreasing. However, the fact that the risks connected with consequences of tree crash are decreas-ing more slowly, is still alarming. The detailed graphs and tables in the bachelor thesis show the number of casualties connected to a traffic accident caused by a crash with a fixed obstacle and they prove that the consequences of accidents caused by a crash with a tree are worse than the consequences of accidents caused by a crash with a crash bar-rier, even though they both are considered a fixed obstacle. Last but not least the costs and total economic losses caused by the highest negative factor, i.e. the accident rate, are calculated by using the tables and graphs.
