3D models of rock relief based on various data
Pecáková, Kateřina ; Hartvich, Filip (advisor) ; Jelének, Jan (referee)
The use of digital elevation models is becoming increasingly used as a scientific method, thanks to the advancement of technologies and public accessibility, particularly in the fields of geomorphology and physical geography. The use of UAV significantly facilitates data collection and subsequent creation of a digital model through the structure from motion (SfM) process. Another data collection method employed in the research is the laser scanning using terrestrial laser scanner (TLS). The aim of the study is to create digital models using these methods and to compare them using the software environment of Agisoft Metashape and CloudCompare software. Additionally, it investigates the influence of georeferencing points on the quality and accuracy of the models. Furthermore, a comparison of the individual methods is conducted based on such parameters as time, costs, data flexibility, environmental impact, and others. The study also seeks to determine the influence of the digital model parameters on obtaining secondary information from the DEMs, such as slope azimuth and geometry of structural planes and joints, used for example in the research of the prevention of potential rockfalls. The results indicate that the use of UAVs is suitable, if not the best option, for geomorphological features in...

3D model of the Chapel of Saint Barbara
Komoňová, Pavla ; Nosek, Jakub (referee) ; Kalvoda, Petr (advisor)
The aim of this bachelor thesis is to create two 3D txtured models of the chaple of St. Barbara in Rudice. The models were created from images taken with a CanonEOS 6D MarkII SLR camera and a Xiaomi 10T Pro mobile phone using Agisoft Metashape Professional software. The achieved accuracywas tested using control points and a reference point cloud from laser scanning. The 3D model was published on the website using Sketchfab.

3D model of the Chapel of Our Lady of the Snows near Tvarožná
Komarov, Vladimir ; Vondrák, Jiří (referee) ; Nosek, Jakub (advisor)
The aim of this bachelor's thesis was to create a georeferenced 3D model of the Pilgrimage Chapel of Our Lady of the Snows in Tvarožná using photogrammetry and laser scanning technology. To achieve this goal, the coordinates of the tie points and control points on the chapel and its immediate surroundings were measured and determined. Photogrammetric images of the chapel's exterior were taken using low-cost cameras, specifically a Xiaomi Mi 10T Pro mobile phone and a DJI Mavic Air 2S drone, which allowed for automated processing in Agisoft Metashape software. The accuracy achieved was analyzed using control points and a reference TLS point cloud created in Trimble RealWorks software. The resulting 3D model was published on the faculty's website.

Construction of a small portable 3D printer
Netušil, Jan ; Vyroubal, Petr (referee) ; Bayer, Robert (advisor)
The study is dedicated to the description of 3D FDM printing technology, compares different types of 3D FDM printers and analyzes key components, especially those necessary for a stable portable 3D printer design. It also includes the specific design of the portable 3D FDM printer solution, its assembly, the actual enhancement of the design, and the design and implementation of the braking arresting elements. It also addresses the printing testing of advanced construction materials suitable for 3D FDM printing and provides a cost estimation and evaluation of the cost-effectiveness of building a portable 3D FDM printer.

University climbing centre, Pardubice
Grund, Michal ; Remeš, Josef (referee) ; Müller, Jan (advisor)
The subject of the bachelor's thesis is the design of a new climbing center and the preparation of construction documentation. The building of the University Climbing Center in Pardubice is located on the southern side of the city of Pardubice, on the border of the Dukla housing estate. The construction is situated in a built-up area on flat terrain. It is a 4-story building in the form of an oval with one underground floor. The roof structure is mono-pitched with a coating of hydro insulation weighted down with washed river pebbles. The building is divided into 3 functional units. The main function of the building is served by the climbing wall, which is accessible from the underground floor and runs across all floors. The second above-ground floor houses a boulder wall with facilities, forming the second functional unit. The last third function consists of space for both trainees and the public on the first above-ground floor, where there is a reception with a rental service and a café with seating in a glazed arc space. The sports facility is designed for a total of 60 trainees. The building is designed with nearly zero energy consumption in a low-energy standard. The design also accounts for the use by persons with limited mobility and orientation. The structural system of the building is reinforced concrete monolithic. The vertical perimeter structures are reinforced concrete with a thickness of 200 mm with contact insulation ETICS with mineral wool boards with a thickness of 200 mm. Internal vertical and horizontal load-bearing structures are of reinforced concrete with varying thicknesses. The roof structure consists of steel rolled I profiles anchored to the vertical walls. The roof assembly is on a load-bearing trapezoidal sheet with a coating of hydro insulation made of TPO foil weighted down with washed river pebbles. The building is founded on a flat foundation slab with a thickness of 350 mm. A terrace for seasonal operation of the café and a small forest park with a playground will be created on the site.

Reinforced concrete structure of the climbing wall building
Válek, Jakub ; Kostiha, Vojtěch (referee) ; Požár, Michal (advisor)
Bachelor’s Thesis deals with the design and assessment of selected reinforced concrete slab and other parts of reinforced structure of the university climbing centre in Pardubice. The static analysis of the structures was performed using the SCIA Engineer 22.1 program based on the finite element method. This analysis was verified by hand calculation. The progress of the design responds to valid European regulations and standards ČSN EN 1992-1-1, ČSN EN 1991-1 to 7 and ČSN 73 1201. The finished work is the design and elaboration of drawings of the shape and reinforcement of the given parts. The design of the structures was made using BIM coordination with other specializations that carried out the designs of the other parts of the building.

Route control
Dolobáč, Dávid ; Janáková, Ilona (referee) ; Richter, Miloslav (advisor)
This thesis sets itself the task to detect geometric changes, located on a previously known route, which is considered as a template or pattern. Geometric changes represent rigid transformations of objects in a scene, specifically their rotation, displacement and their combinations. Another type of change is the addition of new or removal of original objects. The original route is captured with a monocular camera and by using methods of photogrammetry, a 3D model of a scene in a point representation is reconstructed from the video sequence. In the same manner, a 3D model of the scene containing changes is created, but this model captures only the local section of the original route. This local point cloud is registered in the 3D model of the original route, so that the 3D models can be directly compared with each other. The investigated space is divided into cubic voxels of the same size which are successively traversed and the degree of similarity of local surfaces is investigated for each of them. The solution results in 3D points from both clouds marked as changed or unchanged. The mentioned methods are tested on real data in scenarios with different geometric modifications of the scene and the evaluation of change detection is implemented as in the case of a binary classifier.

Easter eggs scanning module
Pitrun, Tomáš ; Janáková, Ilona (referee) ; Honec, Peter (advisor)
This master thesis deals with the design and implementation of a preparation for scanning the museum's collection of Easter eggs. A monochrome line scan camera combined with RGB lighting and stepper motor is used to capture the Easter eggs. The control of the whole fixture is solved by using an Arduino Mega microcontroller in combination with the developed PCB. The data from the camera are processed in software on a PC using Matlab. Finally, a 3D model of the easter egg with the scanned texture is created using the Processing library.
