Goal of the thesis is comparing selected materials, executing series of mechanical test and selecting suitable material for printing high-quality plastic parts for use in automobiles, especially for reproduction of parts that are no longer made for oldtimers and for use in motorsport.

V posledním desetiletí došlo ke zvýšení zájmu o užití 3D dat k biometrické identifikaci osob. Možná vůbec největší výzkum proběhl v oblasti 3D rozpoznávání podle obličeje, přičemž je v současné době dostupných vícero komerčních zařízení. V oblastni rozpoznávání podle 3D geometrie ruky byl v minulých letech proveden určitý výzkum jehož výsledkem však nebylo žádné komerční zařízení. Nezávisle na tomto výzkumu se v posledních letech velmi rozšířil trh s cenově dostupnými 3D sensory, což potenciálně umožňuje jejich nasazení v mnoha typech biometrických systémů. Hlavním cílem této práce je vytvořit funkční vzorek bezdotykového systému pro rozpoznávání osob podle 3D geometrie ruky, který bude používat novou levnou kameru RealSense 3D vyvíjenou v současné době firmou Intel. Jedním z problémů při použití RealSense kamery je její velmi malý form factor, který je příčinou nižší kvality výsledných snímků v porovnání s velmi drahými alternativami, které byly použity v již dříve zmíněném výzkumu 3D biometrických systémů. Práce se snaží analyzovat robustnost různých 2D a 3D příznaků a vyzkoušet několik různých přístupů k jejich fúzi. Rovněž je vyhodnocena výkonnost výsledného systému, kde je ukázáno, že navržené řešení dosahuje výsledků porovnatelných se state-of-the-art.

The diploma thesis is focused on an optical method for 3D scanning. There is selected photogrammetry for creating 3D models. In the practical part, a mechanism for automatic photo capture is designed and manufactured and 3D printed with using a digital camera, Arduino microcontroller and stepper motors. There are proposed two methods of capturing photographs with which digital twins of reference objects are created. The result of the work is a functional 3D scanner. The next are evaluated used methods as well as the production costs and the time required by the operator when creating a digital copy of the object is listed.

This diploma thesis describes the implementation of a 3D model of two objects using laser scanning. This paper deals with the accuracy evaluation of several data interpretation. The first two methods are the outputs of the results from the FARO SCENE program and other interpretations are the outputs from the TRIMBLE REAL WORKS program. To assess accuracy and veracity, the exact test field of points previously built in the AdMas complex was used. The result of the project is a georeferenced 3D model of two objects with the surrounding environment.

Organ-on-chip models are a rapidly evolving and promising tool for studying human physiology and disease and developing therapeutics. However, due to the lack of fabrication processes of pertinent precision to deliver well-defined architectural and mechanical elements, organ-on-chip models have been limited in recapitulating structural and biomechanical features of many tissues, which has impeded the modeling power and clinical relevance of these tools. The elusive in vitro replication of the pumping function and mechanical loading of the human heart, an outstanding instance of a structurally and mechanically complex physiological system, exemplifies the need for stronger fabrication processes. In this work, we investigated the potential of two-photon direct laser writing (TPDLW), an emerging high-precision fabrication technique, in enabling the generation of structurally and biomechanically complex organ-on-chip models. We first identify the functional principles, advantages and limitations of TPDLW, and review existing applications of TPDLW for in vitro studies. Inspired by the fabrication versatility of TPDLW, we then engineer a microfluidic cardiac pump powered by human stem-cell-derived cardiomyocytes (hiPSC-CM), aiming to replicate the ventricular pumping function on a chip by constructing miniaturized analogues of the functional elements of the human heart. We specifically fabricate a microscale metamaterial scaffold with fine-tuned mechanical properties to support the formation and cyclic contraction of an unprecedentedly miniaturized induced pluripotent stem cell derived ventricular chamber. Furthermore, we fabricate microfluidic valves with extreme sensitivity to rectify the flow generated by the ventricular chamber. The integrated microfluidic system recapitulates ventricular fluidic function and exhibits for the first time in vitro all phases of the ventricular hemodynamic loading pattern. Finally, we demonstrate a technique of increasing the fabrication output of TPDLW that could enable its broader adoption. Together, our results highlight the potential of high-precision fabrication in expanding the accessible spectrum of organ-on-a-chip models towards structurally and biomechanically sophisticated tissue architectures. This dissertation is accompanied by a set of supplementary videos depicting the results of our experimental efforts. Movie 1 shows a cardiac tissue beating on an inverted hexagon scaffold. Movie 2 shows a compressive test on helical scaffold that is later embedded in a cardiac tissue. Movie 3 show a beating cardiac chamber on helical scaffold that can generate measurable flow. Movie 4 shows a functional suspension valve that is later embedded in the device with the cardiac chamber. Movie 5 shows the function of a suspension valve that rectifies oscillating flow. Movie 6 shows that the same suspension valve can rectify flow of increasing frequency. Movie 7 shows that the combined chamber and valves exhibit directional flow. Finally, movie 8 shows that the addition of afterload in the combined system leads to the emergence of isovolumetric phases. / 2023-09-24T00:00:00Z

My paper work deals with the 3D active triangular method of building reconstruction. First, there was a measuring triangular system created. Then the way of its automatic calibration was proposed and consequently also performed. Also algorithms for the automatic detection of the sample projected were proposed. Algoriths were presented with several sample buildings. The result of these algorithms are 3D models of individual buildings. In the end achieved results nd restrictions of the system proposed were assessed.

Based on binocular vision the human eye is capable of generating the observed spatial perception of the object. Nowadays 3D imaging of two-dimensional surface is in vogue especially in the cinema industry. However, 3D imaging is gradually getting into other industries especially in other parts of everyday life (advertisements, presentations, entertainment ...). 3D images can be created in various ways, some of which are detailed in this master´s thesis. This thesis deals with the description and the drawing up of a 3D display which provides a three-dimensional image without using auxiliary objects such as glasses. The display unit produces a three-dimensional image at a fundamental level, which consists of providing high-speed rotation of the display and creates the current portion of the object in specified sections.

The project developed under the engineering studies, solves the problem of production of a prototype car using modern technology, reverse engineering and CAD / CAM. Based on the literary study of the issue, was designed process of digitization of the physical model of car, including the treatment and processing of data. Follow-up step was to verify the production of the additive rapid prototyping technology - FDM method.
