Design of a mobile projection device supporting the virtual reality environment
Šooš, Marek ; Blecha, Radim (referee) ; Tůma, Zdeněk (advisor)
This work deals with the analysis of the state and development of virtual reality and AR. In this work I described in detail the advantages and disadvantages of individual technologies, history, present state and trends in development these technologies. In addition to modelling components in a virtual environment, the current state of the art allows the assembly or disassembling of individual machinery as well as testing their functionality and mechanical properties, using special goggles and gloves. The basis for creating 3D images are special projectors, in one, two, or quadruple configurations. The aim of this bachelor thesis is to design a modular and flexible box for the projectors. The designed concept allows for different flexible arrangements of one, two or four projectors, while providing us with simple and accurate alignment.

2D Point-cloud segmentation for curve fitting
Šooš, Marek ; Krejsa, Jiří (referee) ; Králík, Jan (advisor)
The presented diploma thesis deals with the division of points into homogeneous groups. The work provides a broad overview of the current state in this topic and a brief explanation of the main segmentation methods principles. From the analysis of the articles are selected and programmed five algorithms. The work defines the principles of selected algorithms and explains their mathematical models. For each algorithm is also given a code design description. The diploma thesis also contains a cross comparison of segmentation capabilities of individual algorithms on created as well as on measured data. The results of the curves extraction are compared with each other graphically and numerically. At the end of the work is a comparison graph of time dependence on the number of points and the table that includes a mutual comparison of algorithms in specific areas.

3D point cloud segmentation for industrial bin-picking
Šooš, Marek ; Škrabánek, Pavel (referee) ; Shehadeh, Mhd Ali (advisor)
Diplomová práca sa zaoberá segmentáciou 3D mračna bodov pre priemyselné výbery zo zásobníkov, čo je kľúčová výzva v oblasti priemyselnej robotiky. Cieľom práce je navrhnúť a implementovať efektívny algoritmus na segmentáciu a registráciu 3D bodov mračien, a tým vylepšiť presnosť, rýchlosť a efektívnosť bin-picking operácií. Prínosom diplomovej práce je prezentácia autorovho vlastného riešenia vytvárania umelo generovaných dát potrebných na trénovanie. Výsledkom práce je symbióza výhod rýchleho segmentáčného algoritmu založeného na strojovom učení, a kvalitného, robustného ale pomalého registračného algoritmu založeného na geometrickom princípe. Funkčnosť, spoľahlivosť a kvalitu vytvoreného algoritmu boli verifikované aj experimentálne na rôznych typoch objektov a rôznych datasetoch. Výsledky práce ukazujú, že navrhnutý algoritmus prináša rýchle, spoľahlivé, a komplexné riešenie problému bin-picking. Generovanie dát na mieru znižuje čas a náklady na aplikáciu takéhoto systému. V spojení s komplexným systémom riešenia problému, je možné jednoducho vytvárať riešenia pre rozmanite a špecializovane úlohy bin-pickingu. Dosiahnutými výsledkami prispieva k rozvoju metód segmentácie bodových mračien a ich aplikácií v rôznych priemyselných a vedeckých oblastiach. Zavedením navrhnutého systému do praxe, výrazne prispeje k zvýšeniu výkonnosti a spoľahlivosti navrhovanej automatickej linky.
