Surveying of the selected object - 3D model
Petráněk, Matěj ; Švejda, Jan (referee) ; Bartoněk, Dalibor (advisor)
Diploma thesis is focused on the creation of a georeferenced point cloud and mesh model of the church of St. George in Bořitov and the documentation of the fresco of St. Christopher in the same church. The point clouds and mesh models were created based on a combination of photogrammetric processing and terrestrial laser scanning. The documentation of the fresco of St. Christopher is made in the form of the orthomosaic. The thesis comprehensively describes the creation process, especially in Agisoft Metashape and Cyclone 3DR. It also documents the accuracy achieved and suggests other forms of using the resulting products.

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.

3D model of the selected object
Veselý, Milan ; Nosek, Jakub (referee) ; Kalvoda, Petr (advisor)
The aim of the thesis was to assess the accuracy of photogrammetric results from images taken with a low-cost Xiaomi Mi 10T Pro camera and a professional digital SLR camera Canon EOS 6D Mark II with a 24 mm fixed lens. The chapel of St. John of Nepomuk near Guntramovice was chosen as the subject for the images. Forty-nine insertion and control points were targeted and scanned at the chapel. Block and beam alignment and creation of 3D mesh models was performed in Bentley ContexCapture software. The standard deviations of all three axes (X, Y, Z) and positional standard deviation on the control points and deviations relative to a reference point cloud acquired with a ground-based laser scanner were statistically tested. The results show that, with the right imaging and processing methods, comparable results can be achieved using a low-cost camera.

Návrh rozložení přibližovacích linek na základě fotogrammetrie v Thajsku
Petrovičová, Lucia
Suitable skidding trail layout is important in sustainable forestry system, thus can minimise the damages to trees and economical losses. In a cooperation between Mendel University in Brno and Kasetsart University in Bangkok a potential use of photogrammetry based skidding trail layout was evaluated. Certain plots of teak plantation in Thong Pha Phum were captured with and further processed in Agisoft Metashape software. On obtained orthophoto single trees were distinguished and understory trees for thinning from below were identified on Weighted Voronoi diagram base. On Kernel Density Estimation base a tree density estimation raster output were created. Considering irregular teak spacing a subjective approach for skidding trail layout design was applied, with emphasis to shorten skidding distances and reducing the possible damages to remaining trees and soils.
